Abstract

A tapered stent made of resilient material for interconnecting portions of a Fallopian tube after a resection procedure. The stent is tapered to conform to the tapered inner surface of the Fallopian tube and is provided with at least one suture on at least one end for use in inserting the stent within the Fallopian tube and to secure the stent in place.

Claims

1. A method of joining together resected end portions of a Fallopian tube which has been resected resulting in a first distal portion having a cut end portion and a fimbriated end portion and a second proximal portion having a cut end portion, said method comprising:

a) providing a stent having a diameter substantially equal to the inner diameter of a Fallopian tube, and having first and second end portions and at least one suture means secured to each of said end portions;

b) inserting the suture means which is secured to said first end portion of said stent into said first distal portion of said Fallopian tube through said fimbriated end portion, past said cut end portion of said first distal portion and said second proximal portion, and through a wall of said cut end portion of said second proximal portion;

c) pulling on said suture means which is secured to said first end portion of said stent to pull said stent into contact with said resected end portions, and bringing said resected end portions into contact with each other; and

,

d) securing said stent in place at said resected end portions by means of said suture.

2. An intraluminal stent for use in carrying out a surgical procedure for joining together first and second ends of a tapered portion of a resected Fallopian tube, said stent comprising an elongated solid member formed of a biologically compatible, resilient material, said stent being uniformly tapered throughout its length for substantially conforming throughout its length to the taper of said Fallopian tube.

3. A stent according to claim 2 having a taper of from about 2°

to about 6°

.

4. A stent according to claim 2 having a length from about 2 centimeters to about 4 centimeters.

5. A stent according to claim 2 formed of sponge rubber.

6. A stent according to claim 2 formed of a soft plastic.

7. A stent according to claim 2 provided with at least one suture secured to at least one end portion of said stent.

8. A stent according to claim 7 wherein said suture has a length of at least about 10 centimeters.
