Definitions

  • the present invention relates to medical devices, and more particularly to a double- or triple-lumen catheter incorporating an inflation means for dilating a woman's cervix while providing access through the woman's cervix to the uterus.
  • medical procedures in human patients include, but are not limited to, endometrial (uterine) biopsy, cervical dilatation and curettage, and cervical dilatation and evacuation procedures.
  • endometrial (uterine) biopsy biopsy
  • cervical dilatation and curettage curettage
  • cervical dilatation and evacuation procedures examples include, but are not limited to, artificial insemination, procedures requiring access to the endometrium and similar procedures.
  • the conventional method for dilating a patient's cervix employs a series of sequentially larger solid metal rods which are progressively, in order of smallest to largest, inserted into the patient's cervix, thereby producing a mechanical dilation of the cervix.
  • solid metal rods for cervical dilation. Notwithstanding the obvious discomfort to the patient, once the cervix has been dilated to a desired diameter, the current rod must be removed before access through the cervix to the patient ' s uterus is possible.
  • a cervical dilation device that dilates a patient' s cervix while providing access through the cervix to the patient's uterus.
  • a cervical dilation device that provides a large access aperture through the patient's cervix such that a medical device may be easily and painlessly inserted through the cervix and into the patient's uterus.
  • a dilation device that is minimally intrusive and comfortable to the patient.
  • a local anesthetic to minimize the pain.
  • Jeyendran a time-release insemination device is disclosed wherein an elongated cylindrical nipple is fit into a patient's cervical canal.
  • the nipple may be extended so that it projects past the cervical canal and into the uterine cavity.
  • the Jeyendran device provides access through a patient's cervix into the uterine cavity, the device provides no means for enlarging, or dilating, the cervical canal.
  • a custom molded cervical cap wherein the finished cervical cap may include a valve having an opening of about 2- 10mm.
  • the valve allows the egress of fluid from the uterus during the use of the cervical cap.
  • the Koch cervical cap does not provide a means for enlarging, or dilating, a patient's cervical canal.
  • a contraceptive cervical cap wherein a marker is inserted into the cervical canal to "mark" the location of the opening of the cervical canal. Again, the marker does not enlarge a patient's cervical canal, but rather is held in place by the canal and the cervical cap until the cervical cap solidifies. Then, once the cap is removed, the marker is removed, thereby creating an effluent tube through the cap.
  • a conventional uterine injector is commercially available, e.g., a Zirmanti Uterine Injector from BEI Medical Systems Company, Inc., that provides a means for enlarging or dilating a patient's uterus.
  • the injector comprises a balloon positioned on the end of a catheter wherein medical personnel insert the balloon into a patient's uterus and, once properly positioned, inflate the balloon. When the balloon is inflated it acts as a stopper which prevents the catheter from accidentally egressing from the uterus.
  • the disadvantage with this device is that the cervical canal maintains the same size opening; that is, the cervical canal is not enlarged.
  • the cervical dilation device of the present invention solves the problems associated with the conventional method for dilating a patient's cervix by providing a double-lumen catheter having a first end and a second end.
  • the double-lumen forms a tubular balloon connected to the second end of the catheter wherein the outer surface of the tubular balloon and the inner surface of the tubular balloon are connected by one or more supports.
  • the catheter is integrally connected to the outer surface of the tubular balloon such that when air is pumped through the catheter, the tubular balloon is inflated. As the tubular balloon is inflated, the supports ensure that the inner surface moves with the outer surface thereby creating an enlarged access aperture through the cervix and into the patient's uterus.
  • the cervical dilation device of the present invention there are several advantages in using the cervical dilation device of the present invention.
  • a physician can access the patient's uterus, such as by inserting medical instruments, without having to remove the dilation device.
  • the cervical opening of a patient only needs to be penetrated once as compared to the multiple penetrations required by the conventional metal rods.
  • the physician does not have to worry about reflex closure of the cervix that typically occurs when a conventional cervical dilation device is removed from the patient.
  • the physician can control the rate and level of inflation thereby creating an access aperture only as large as required.
  • the present invention comprises a triple-lumen catheter wherein the triple-lumen connected to the second end of the catheter forms an inner, or first, tubular balloon and an outer, or second, tubular balloon.
  • the inner tubular balloon functions as the inflation means, as discussed above, for dilating the patient's cervix
  • the outer tubular balloon provides a means for delivering a drug, e.g., a local anesthetic, to the surface of the cervix prior to the inflation of the inner tubular balloon.

  • two catheters are used: one for inflating the inner tubular balloon and one for delivering a drug into the outer tubular balloon.
  • Each of these two catheters accesses one of the tubular balloons, such as on opposite sides of the device, in order to provide a physician with complete and unhindered access to the uterus.
  • the principal advantage to using a triple-lumen is the ability of the physician to reduce the potential pain and discomfort for the patient prior to the subsequent medical procedure.

Abstract

L'invention concerne un dispositif (100) servant à dilater le col de l'utérus afin de pouvoir accéder à l'utérus sans difficulté. Ce dispositif (100) comprend un tube creux allongé (102) pourvu d'un bulbe de gonflage (104)et des moyens (106) servant à dilater le col de l'utérus. Dans le mode de réalisation préféré, le ballonnet tubulaire (106) possédant une surface extérieure (108) et une surface intérieure (110) définissant une ouverture d'accès (112) et reliées par des supports (114). Simultanément au gonflage du ballonnet, la surface extérieure et la surface intérieure se rapprochent, ce qui agrandit l'ouverture d'accès. Dans un autre mode de réalisation, on place un deuxième ballonnet tubulaire (502), accouplé à un deuxième cathéter (508), autour du premier ballonnet tubulaire, de façon à relier totalement la surface intérieure du deuxième ballonnet tubulaire à la surface extérieure du premier ballonnet tubulaire. La surface extérieure du deuxième ballonnet tubulaire (502) est perforée, ce qui permet d'effectuer une administration médicamenteuse.
