Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
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.
Claim 2
Independent Claim
197 words
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.
Claim 3
Dependent Claim
62 words
