Definitions
- the present invention relates to a single-use gynecological medical device intended to produce thermal lesions in the intra-myometrial part of the fallopian tubes by application of radiofrequency. This thermal injury is accompanied by tubal obstruction by thermofusion so as to create definitive tubal sterilization.
- two trocars are usually required, namely an umbilical trocar to introduce the laparoscope (camera) to provide visual feedback to the practitioner on the operation, and a medial suprapubic trocar to introduce a clamp applicator to position and tighten the clips.
- another trocar can be introduced through the abdominal wall to allow the operator to better expose the tubes.
- the abdominal cavity is put under pressure (CO 2 inflation) to distend the abdominal wall and allow the organs to be visualized and mobilized safely.
- Laparoscopic surgery has several advantages over conventional surgery by transverse incision of the abdominal wall (laparotomy). Laparoscopic perforations, which are smaller than the incisions made during conventional operations, are less painful for the patient and allow for accelerated recovery and convalescence. Hospital stays are thus reduced to a minimum. At the same time, laparoscopic surgery takes less time and is less expensive than conventional surgery to perform the same procedure.
- thermofusion method of the tubes makes it possible to sterilize women by blocking the lumen of the tubes leading to the uterus.
- the thermal effect is accompanied by an alteration of the tubal ciliary epithelium and a contraction of the peri-tubal muscles (myometrium) and is responsible in a few days to a few weeks for a thermofusion of the tubal mucosa, responsible for permanent tubal obstruction.
- the sensor is connected by a feedback line to a control circuit which automatically modulates the power of the radio frequency applied to the electrode based on the feedback signal received by the temperature sensor.
- the principle of radiofrequency treatment can be used for the percutaneous treatment of liver metastases or for the transrectal treatment of prostate tumors, for the percutaneous treatment of varicose veins of the lower limbs according to the same principle of thermofusion or in gynecology for the percutaneous treatment of uterine fibroids.
- the device is inserted transvaginally into the uterus and then into the fallopian tube at the end.
- Document US5303719 describes a surgical instrument intended to be used in a female sterilization operation comprising an elongated endoscope, also called a hysteroscope, provided with an operating channel through which an elongated flexible endoscopic surgical instrument is inserted.
- an elongated endoscope also called a hysteroscope
- the endoscope is inserted through the patient's vagina, cervix and uterus to the fallopian tube. It thus allows you to visualize the ostiums of the fallopian tubes (openings where the fallopian tubes enter the uterine cavity).
- Patent US4700701 relates to a device for sterilizing the fallopian tubes comprising a catheter having a free working end and an opposite control end.
- the catheter includes an outer sleeve and a concentric inner core.
- a thermoelectric cautery is mounted on the free end of the catheter and is electrically powered by a Peltier cell consisting of a bimetallic structure formed of a hollow cylindrical copper substrate. Insulated electrical wires are electrically coupled to the Peltier cell and extend inside the catheter to a suitable electrical power source (preferably a direct current source) through a current regulator and a switch.
- the device works by cryo-cauterization, for example at -40° C, so as to destroy part of the epithelium of the fallopian tube placed in contact with the surface of the Peltier cell.
- the next step is to activate the generator using a “switch” positioned on the handle of the instrument.
- Thermal injury to said tissue responds by causing intense inflammation and scarring of the tissue.
- the end result is the replacement of the tubal epithelium and muscle tissue fibers exposed to cauterization with scar tissue, resulting in occlusion of the tube (where there was a hollow tube, there is now a solid column of fibrous tissue) causing the definitive and irreversible sterilization of the patient.
- Patent US5095917 relates to an irreversible sterilization method which combines the destruction of the epithelium of the fallopian tubes by hyperthermia with the insertion of a biodegradable plug.
- the destruction of the mucosa causes an inflammatory reaction and the plug serves as a substrate to initiate the occlusion process.
- the method comprises the steps of destroying a superficial layer of the utero-tubal junction and inserting means for promoting the growth of scar tissue at said point of destruction of said utero-tubal junction.
- the sterilization instrument used includes a hollow tube containing one or more caps of biodegradable material which may or may not contain a drug such as tetracycline hydrochloride to delay breakdown of the initial clot and enhance scarification.
- the hollow tube is also equipped externally with copper wiring intended to be connected to a high frequency bipolar current generator via electrical cables.
- a bipolar coagulation current of approximately 5 watts for a duration of between 5 and 15 seconds is sufficient to produce irreversible but shallow thermal damage to the tubal epithelium.
- a piston is activated and the instrument is simultaneously withdrawn slightly, which has the effect of releasing a plug which will then be at the exact level of the destroyed mucosa of the utero-tubal junction .
- the application of bipolar electrical energy causes an immediate inflammatory reaction. Part of this reaction is "edema", which is swelling of the tissues. This natural mechanism keeps the cork in its position.
- the inflammatory cells leave the vessels and then colonize the damaged tissue. They first work to seal the area and then, with other cells, they repair the injury.
- the proliferation of fibroblasts i.e. cells that form connective tissue
- This proliferation process can be enhanced by certain medications, such as tetracycline hydrochloride, contained in the cap. Thanks to the presence of the plug, the fibroblasts will not only colonize the damaged tissue, but also the plug. Other cells, such as macrophages, will "clean" the area and help digest the material the plug is made of. After a period of 3 to 6 weeks, the cells gradually disappear and leave behind a dense structure of fibers called scar tissue, which will also include the area where the plug has been inserted. This process therefore results in irreversible occlusion of the tubal lumen, thus rendering the patient sterile.
- certain medications such as tetracycline hydrochloride
- patent FR2748648 describes an apparatus and a method for transcervical sterilization and embolization using a catheter, and more particularly a temperature-controlled bipolar radiofrequency catheter, as well as its use to cause thermal lesions in the fallopian tubes.
- the transcervical sterilization apparatus includes an elongated catheter having a distal end and a connector on the opposite end having wires for connection to an electrosurgical generator that provides radiofrequency energy in the amount can be controlled. At least two bipolar electrodes, located around the distal end of the catheter, are spaced apart from each other.
- the device is intended to be used using an operating hysteroscope having an operating channel, the curvature takes place only at the exit of the hysteroscope into the uterine cavity.
- the solution of the present invention allows ideal introduction and positioning of the device in the entrance to the Fallopian tube (intra-myometrial portion), and in particular of its active emission zone of radiofrequency, and the possibility, thanks to the means of blocking the curvature of the applicator, of positioning the device in the second fallopian tube in an extremely rapid, precise and efficient manner to carry out its occlusion, all without having to do new potentially tedious adjustments of said curvature of the applicator
- the tubular applicator comprises a bendable zone having a length of between approximately 2 and 10 centimeters from its distal end, preferably between approximately 4 and 8 centimeters.
- the maximum angle of curvature formed between the longitudinal axis of the elongated tubular applicator and a tangent to its distal end is between approximately 30° and 90°.
- the curvature actuator is a rotary wheel.
- This rotary wheel can be notched or not.
- the advantage of this notching is the maintenance of the angulation to facilitate contralateral treatment.
- the curvature actuator is a traction wheel that can be turned in two opposite directions of rotation around a pivot.
- the elongated tubular applicator contains at least one cable fixed on the one hand in the immediate vicinity of its distal end and on the other hand to the traction wheel, said cable being able to slide over a distance of a few millimeters inside the elongated tubular applicator, rotation in one direction of said traction wheel causing traction of said cable resulting in a curvature in a first direction of the distal end of the elongated tubular applicator as the wheel is turned, and rotation in the opposite direction of said traction wheel causing a traction of said cable resulting in a curvature in a second opposite direction of the distal end of the elongated tubular applicator as said wheel is rotated
- the curvature blocking means is a press button linked to the curvature actuator.
- the elongated tubular applicator comprises, from its distal end, an active radiofrequency emission segment measuring between approximately 4 and 10 millimeters and preferably between approximately 6 and 8 millimeters.
- the elongated tubular applicator is crossed longitudinally by at least two separate conductive filaments respectively forming at their distal ends two radiofrequency electrodes spaced axially from each other and arranged in the active emission segment radio frequency.
- the electrode is called bipolar, thus providing maximum safety for the procedure.
- each radiofrequency electrode has an axial length of between approximately 2 and 4 millimeters and preferably approximately equal to 3 millimeters.
- an electrical insulating segment is placed between the two radio frequency electrodes.
- the insulating segment has an axial length approximately equal to 1 millimeter.
- the distal end of the elongated tubular applicator comprises an atraumatic round tip measuring between approximately 1 and 2 millimeters in length. This tip is also insulating and thus prevents the distal diffusion of the thermal effect, thereby reducing the risk of collateral tissue damage. [0053] This solution allows the practitioner to position the device more easily in the desired area, without risking damage to the tissues (vagina, uterus, tubes).
- the tubular applicator includes a mark opaque to X-rays and/or ultrasound placed upstream of the active radiofrequency emission segment.
- the manual gripping means is equipped with an indicator light indicating the operation of the radio frequency source.
- the manual gripping means is equipped with an activation/deactivation button (“switch”) of the radio frequency source.
- switch activation/deactivation button
- the manual gripping means contains the radio frequency source and a removable battery for powering the radio frequency source. This solution therefore eliminates the need for an external RF generator.
- the stop means is a “stent” mounted in a substantially cylindrical sheath surrounding the tubular applicator, said stent being deployable like an umbrella to form a cone narrowing as one approaches the active radio frequency emission segment.
- Figure 8 is a longitudinal sectional view of the handle of Figures 6 and 7,
- Figure 9 is a detailed sectional view of the distal end of the elongated tubular applicator of the medical device of the present invention.
- Figure 16 is a view of an alternative embodiment of Figure 14 in which the balloon is replaced by a radially expandable stent, and
- a manual gripping means 20 of the ergonomic handling handle type formed of two plastic half-shells, arranged at a proximal end la of the elongated tubular applicator 10, and
- the elongated tubular applicator 10 comprises, at a distal end 1b of the device 1, an active radio frequency emission segment 40 connected to the radio frequency source 30 and which will be described in more detail in relation to the Figures 9 and 10.
- the active radio frequency emission segment 40 measures axially approximately 6 to 8 millimeters, for example approximately 7 millimeters.
- the distal end 1b can take, in use and thanks to the mechanical curvature actuator 50, different curvatures (defined by their respective radii of curvature) and form an angle a, defined between the axis XX' and the tangent T at the distal end 1b, between approximately 30° and 90° depending on the configuration and conditions of use of the gynecological medical device 1.
- the handling handle 20 also includes a trigger switch type switch button 56 (usable for example with the practitioner's thumb) to start or stop the radio frequency source 30, as well as an indicator light 57 (of the type LED for example) serving as an indication light that the radiofrequency source 30 is active when the medical device 1 is used.
- a trigger switch type switch button 56 usable for example with the practitioner's thumb
- an indicator light 57 serving as an indication light that the radiofrequency source 30 is active when the medical device 1 is used.
- two cables 58 on the left
- 59 on the right
- metallic composite materials, for example based on carbon fiber or Kevlar, are possible for their lightness and their solidity
- the tension wheel 51 on either side of its pivot 55, and pass through almost the entirety of the tubular applicator 10 to be fixed at respective points 58b and 59b at the level of the distal end 1b of the medical device 1.
- the two cables 58 and 59 for curving by tension are preferably mounted sliding axially inside the material forming the elongated tubular applicator 10, while being fixed close the atraumatic tip 11 at points 58b and 59b so that the traction effect causing the curvature can occur.
- an implantation zone 12 of the fixing points 58b and 59b of the cables 58 and 59 for curving by tension is provided and positioned as close as possible to the atraumatic tip 11, this so as to optimize the curvature of the elongated tubular applicator 10.
- the cables 58 and 59 will exert their traction force as far as possible from the handling handle 20, which will optimize the formation of the radius of curvature of the elongated tubular applicator 10.
- a radio-opaque marker 18 measuring axially approximately 4 millimeters in length is provided upstream of the second electrode zone 16, at the entrance to the active segment 40.
- Markers 19 of black color are also represented ( see figure 10) every centimeter on the outside of the slender tubular applicator 10, over an axial distance of approximately 5 centimeters.
- Figure 10 illustrates the operation of the medical device 1 when the radiofrequency source is turned on to send its bipolar signal into the active segment 40.
- the curvature of the distal end 1b of the elongated tubular applicator 10 is oriented towards the left using the notched button 51, which indicates that the practitioner will perform his gynecological medical procedure on the left fallopian tube TFG (hysteroscope 80 inclined from right to left from its proximal end, as in Figure 12).
- the practitioner blocks this curvature by pressing the pressure button 60, which prevents any untimely rotation of the tension wheel 51, and therefore any change in curvature of the end distal 1b.
- the practitioner can then trigger the bipolar radio frequency source 30 by pressing the switch button 56 to send an electric current into the copper filaments 14 and 17.
- the indicator light 57 remains lit throughout this phase to indicate to the practitioner that the bipolar radio frequency source 30 is active.
- the practitioner can unlock the pressure button 60, remove the distal end 1b of the elongated tubular applicator 10 from the entrance to the first fallopian tube on the left TFG, pivot the hysteroscope 80 from left to right (see Figure 13) and turn the wheel 51 in the opposite direction, namely clockwise, so as to curve the distal end 1b in the opposite direction (towards the right therefore) before inserting said distal end 1b into the entrance (intramyometrial portion) of the right fallopian tube TFD.
- the practitioner can then perform the same gesture as for the first fallopian tube, namely block the curvature of the distal end 1b of the tubular applicator 10 by pressing the pressure button 60, trigger the bipolar radio frequency source 30 by pressing on the switch button 56 to send an electric current into the copper filaments 14 and 17, which will have the effect of creating locally at the level of the active segment 40 an increase in temperature (>60° G) which will cause destruction by effect thermal (burn) of the tissues of the mucosa of said second right fallopian tube TFD over a small thickness.
- the indicator light 57 also remains lit throughout this phase to indicate to the practitioner that the radiofrequency source 30 is active.
- the practitioner can move the tubular applicator 10 back inside the hysteroscope 80 to bring the entire distal end 1b into sound of the working channel, reposition the hysteroscope in front of the second Fallopian tube TFD (figure 13) by tilting it from left to right (figure 13) before bringing out the distal end 1b of said tubular applicator 10 in order to give it the reverse curvature by acting on the notched wheel 51.
- the practitioner can, after removing the curved distal end 1b from the entrance to the fallopian tube left TFG, turn the hysteroscope 80 and device 1 assembly 180° around its main axis in a simple gesture, and penetrate the distal end 1b, kept curved outside the hysteroscope 80, inside the entrance of the right fallopian tube TFD, always keeping the hysteroscope 80 inserted in the patient's body.
- This is made possible because the pressure button 60 remains active and maintains the curvature of the distal end 1b of the elongated tubular applicator 10.
- the practitioner does not need to remove the assembly consisting of the hysteroscope 80 and the medical device 1 from the patient's uterus U to pass from a fallopian tube to the other.
- the practitioner can, in a single gynecological procedure, treat the second TFD fallopian tube in the same way as the first during a single, rapid and effective intervention.
- the present solution does not require general anesthesia and an operating room, which considerably reduces the inconveniences, the costs incurred and the duration of the intervention. It does not cause tissue trauma because it does not require the use of trocars. Access is via natural routes (hysteroscope referenced 80 in Figures 12 and 13) and there is no risk of migration of a micro insert implanted in the tube since the device leaves no foreign bodies in the tube. patient's body. Finally, there is no phenomenon of re-waterproofing of the tubes.
- the invention is thus the first device offering definitive tubal obstruction by thermofusion with a bipolar energy source limiting the risks for the patient.
- This device has the advantage of not leaving any foreign body in the tissues of the uterus after completion of the thermofusion because the medical device is removed in its entirety.
- the device thus designed can be used easily, by a single operator, quickly, efficiently and with a reproducible gesture.
- the device also has the advantage of offering an inert treatment, not requiring the long-term use of hormones to ensure contraception. It meets a significant demand from patients since at present there is no alternative to general anesthesia and laparoscopy. This device concerns a large market estimated at 650,000 definitive sterilizations in Europe, 900,000 cases in North America and more than 12 million for the rest of the world (Asia and Latin America).
- the medical device 1 can comprise, at its incurvable distal end 1b, a stop means 90 fixing the longitudinal position of the active radiofrequency emission segment 40 once the The distal end 1b of the elongated tubular applicator 10 implanted in the entrance (intramyometrial portion) of the fallopian tube at the desired position.
- the balloon 91 is inflated (air passage inside the tubular applicator for example), which makes it possible to maintain the distal end 1b in position in the tube, and in particular the active radiofrequency emission segment 40 which must be placed as precisely as possible to irradiate the chosen areas.
- the balloon is already in a naturally inflated state, which avoids an inflation step.
- the bipolar radio frequency source is actuated using the switch button 56 of the handling handle 20 so as to emit a radio frequency signal which will burn the surrounding tissue to a small thickness, as described previously. in relation to figures 12 and 13.
- the elongated tubular applicator 10 equipped with its inflated balloon 91 is removed from the entrance to the tube.
- Fallopian and second fallopian tube can be treated as previously described.
- the stop means 90 takes the form of a stent 92 expandable radially in the manner of an umbrella mounted around the tubular applicator 10 (a a priori before the opaque radio indicator 18) and whose operation is similar to the balloon described previously.
- the stent 92 is opened radially (FIG. 17), which allows to maintain the distal end 1b in position in the tube, and in particular the active radiofrequency emission segment 40 which must be placed as precisely as possible to irradiate the chosen areas.
- the stent 92 is folded radially ( Figure 16) to return to its initial position once the first tube has been treated in order to treat the second, or it is folded once both tubes have been treated, so as to be able to easily remove it from the uterus. of the patient the assembly consisting of the hysteroscope 80 and the tubular applicator 10.
