Definitions

  • the invention relates to a device for introducing catheters into a patient's blood vessel, said device comprising an introducer sheath that has a distal end and a proximal end and is traversible by a dilator.
  • the use of the aforementioned devices comprises the following steps: a percutaneous puncture is performed with a needle and through it a wire guide is passed, then removing the needle; the guide is inserted into a dilator in which the introduction device is mounted, until it penetrates the vessel; when removing the dilator and the guide, the device is ready to be used for the passage of a catheter.
  • the invention aims to overcome the aforementioned drawbacks.
  • This purpose is achieved by a device of the type indicated at the beginning and characterized in that said proximal end! of said introducer sheath is continued by a head provided with at least two proximal tubular branches, each of said proximal tubular branches: [a] presenting a proximal access mouth; [b] being communicated with said introducer sheath; and [c] being provided with a hemostasis valve; and because one of said proximal tubular branches is aligned with said introducer sheath, allowing said dilator access to said sheath.
  • the device can be applied in electrophysiology and other vascular techniques (pressure measurement in two or more places) as well as it can be applied in percutaneous procedures in different anatomical places (laparoscopic surgery) by modifying the current introducer trocars.
  • Another important field of application is intensive care, in which the device can remain in the patient for a long number of days.
  • Fig. 1 an elevation view of the device provided with three proximal tubular branches.
  • Fig. 2 a view similar to the previous one with the dilator going through the device.
  • Fig. 3 a view analogous to the previous ones being the device crossed by three catheters.
  • Fig. 4 an exploded partial section, on a larger scale, of the head, the tubular branches and the fixing system.
  • Fig. 5 a view analogous to those of Figs. 1 to 3 corresponding to an embodiment in which the introducer sheath and the head are different pieces.
  • Fig. 6 on a larger scale, a side elevation view, partially sectioned, of a preferred embodiment of the hemostasis valve.
  • the present device comprises an introducer sheath 2 with a distal end 4 (ie the end to be inserted in the patient and away from the person acting with the device) and a proximal end 6 (opposite to said distal end). From this proximal end there is a head 8 that can constitute a single piece with the introducer sheath 2 or be fixedly attached to the sheath 2.
  • the head 8 is provided with two or more proximal tubular branches 10 (three branches 10a, 10b and 10c in the embodiment shown) and one of them, in the figures the proximal branch 10a, is aligned with the introducer sheath 2 and is substantially of the same caliber, so that the device can be traversed end to end by a dilator 12 (Fig. 2); all the tubular branches 10 are communicated with the introducer sheath 2 and are also accessible by the respective proximal access mouths 14a, 14b and 14c, so that this mouth 14 can be pierced by a catheter 16 (Fig. 3); previously one of said proximal mouths 14 has been crossed by a wire guide (not shown) and which is useful for the correct placement of the device in a blood vessel.
  • Each of the tubular branches 10 has a hemostasis valve 18 (Figs. 4 and 6) that opens when it is traversed by a catheter 16 although it hinders an unwanted reflux of blood from the blood vessel that has been penetrated.
  • the device has a side tube 20 that is connected to a tubular branch 10 (tubular branch 10a, in the embodiment described and represented);
  • This side tube 20 is provided with connection means 22, which is preferably a Luer connection, which allows communication with a syringe or with an extension connected to a serum container or other devices.
  • the invention also comprises the possibility that there is a side tube and corresponding connection means 22 for each tubular branch 10; the connection 24 (Fig. 4) of the side tube 20 with the tubular branch 10 takes place downstream of the corresponding hemostasis valve 18.
  • the connection means 22 allows manual washing with a syringe, aspirating blood and re-injecting blood and serum to the patient, in order to remove air from the system prior to catheter insertion.
  • the device comprises fixing fins 26 provided with two holes 28 that allow a fastening with lines or the like, so that a catheter immobilization with respect to the patient is achieved.
  • each system 30 comprises a proximal section 32 located upstream with respect to the hemostasis valve 18; this section 32 is externally threaded and a small tubular element 34 of elastic material is freely housed therein; preferably the outer lateral surface of the tubular element 34 is concave.
  • the proximal section 32 is closed by means of a cap 36 as a cap, internally threaded and which is threadable to the proximal section 32.
  • This cap 36 has an internal axial rod 38 which has an axial hole 40.
  • the mouth of the plug 36 constitutes the proximal mouth 14 for access to the tubular element and it is preferred that the edge of this mouth be rounded or of a truncated conical configuration.
  • a preferred embodiment of the hemostasis valve 18 is shown on a larger scale, which is of special application in the proximal branch 10a aligned with the introducer sheath 2;
  • This hemostasis valve 18 is formed by a body of flexible plastic material. It comprises an upper circular base 42 at the center of which is a hole 44; From this base emerges a brief descending peripheral skirt 46 that surrounds a resistant ring 48.
  • the lower part of this hemostasis valve 18 has an ascending skirt which fits into said descending peripheral skirt 46 and a centrifugal radial part 50; of these two flat portions 52 continue, as sections of a cone by inclined planes; these portions have free edges 54 that tend to keep in contact, and which are separated when the hemostasis valve is crossed by the dilator 12.

Abstract

L'invention concerne un dispositif pour l'introduction de cathéters dans un vaisseau sanguin d'un patient comprenant une gaine d'introduction présentant une extrémité distale et une extrémité proximale et pouvant être traversée par un dilatateur. Dans le prolongement de l'extrémité proximale de cette gaine d'introduction s'étend une tête dotée d'au moins deux branches tubulaires proximales, dont chacune a) présente une bouche proximale d'accès, b) est en communication avec la gaine d'introduction et c) est équipée d'une valve d'hémostase. Une des branches tubulaires proximale est alignée sur la gaine d'introduction et permet l'accès du dilatateur dans la gaine d'introduction.
