Abstract
Abstract A compression anastomosis assembly (10) of, interlocking coupling members (12, 22, 32), particularly suitable for use in achieving anastomosis of tubular organs, having an improved locking feature to prevent inadvertent disassembly of installed coupled members. The design and configuration of the members also provide for ease in placement of the assembly in a living body wherein preferably one assembly member includes a cutting guide (46, 56) and a cutting ring (62) which facilitate use of a cutting implement (86) commonly associated with a device suitable for use during assembly implantation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
229 words
An assembly (10) for compression anastomosis of a tubular structure characterized by a first coupling member (12) being generally a thin wall hollow cylinder having first and second ends with the second end being open and the first end having a surface (16); a second coupling member (22) being generally a thin wall hollow cylinder having open first and second ends and including a first portion (24); a third coupling member (32) being generally a thin wall hollow cylinder having open first and second ends; said first coupling member (12) being dimensioned and configured to receive therein said first portion (24) of said second coupling member (22) with said second coupling member (22) being dimensioned and configured to receive therein at least a portion of said third coupling member (32); and means disposed on said first portion (24) of said second coupling member (22) adapted for locking coaction with complementary means disposed proximate a first end of said third coupling member (32), with each said coupling member being aligned and urged into engagement, said third coupling member (32) forces said first portion (24) of said second coupling member (22) into locking engagement with said first coupling member (12), with said first end of said third coupling member (32) mechanically locking within said first portion (24) of said second coupling member (22) thereby effecting an assembly of interlocking coupling members.
Claim 2
Dependent Claim
229 words
An assembly (10) for compression anastomosis of a tubular structure characterized by a first coupling member (12) being generally a thin wall hollow cylinder having first and second ends with the second end being open and the first end having a surface (16); a second coupling member (22) being generally a thin wall hollow cylinder having open first and second ends and including a first portion (24); a third coupling member (32) being generally a thin wall hollow cylinder having open first and second ends; said first coupling member (12) being dimensioned and configured to receive therein said first portion (24) of said second coupling member (22) with said second coupling member (22) being dimensioned and configured to receive therein at least a portion of said third coupling member (32); and means disposed on said first portion (24) of said second coupling member (22) adapted for locking coaction with complementary means disposed proximate a first end of said third coupling member (32), with each said coupling member being aligned and urged into engagement, said third coupling member (32) forces said first portion (24) of said second coupling member (22) into locking engagement with said first coupling member (12), with said first end of said third coupling member (32) mechanically locking within said first portion (24) of said second coupling member (22) thereby effecting an assembly of interlocking coupling members.
Claim 3
Dependent Claim
26 words
The assembly (10) according to claim 1 characterized in that said first portion means is a land (30) and said complementary means is a projection (36).
Claim 4
Dependent Claim
26 words
The assembly (10) according to claim 1 characterized in that said first portion means is a projection (36) and said complementary means is a land (36).
Claim 5
Dependent Claim
19 words
The assembly (10) according to claim 1 further characterized by including a recess (18) disposed in said surface (16).
Claim 6
Dependent Claim
