Apparatus and method for performing compressional anastomoses
First Claim
1. A compression device for the anastomosis of a hollow organ, comprising:
- (a) a first collapsible member movable between an expanded configuration and a collapsed configuration;
(b) a first tissue retaining member insertable in said first collapsible member to maintain said first collapsible member in said expanded configuration and hold tissue between said first tissue retaining member and said first collapsible member;
(c) a second collapsible member movable between an expanded configuration and a collapsed configuration; and
(d) a second tissue retaining member insertable in said second collapsible member to hold tissue between said second tissue retaining member and said second collapsible member;
wherein said first and second collapsible members are configured and dimensioned to interlock with each other.

Abstract
Apparatus and method for forming a compression anastomosis of a hollow organ. The apparatus comprising a first collapsible member movable between an expanded configuration and a collapsed configuration, the first collapsible member having a longitudinal bore defined by an inner surface, a first mating member, locking structure disposed on the first collapsible member for locking the first collapsible member with the first mating member, a second collapsible member movable between an expanded configuration and a collapsed configuration, the second collapsible member having a longitudinal bore defined by an inner surface, a second mating member, locking structure disposed on the second collapsible member for locking the second collapsible member with the second mating member, and the first member adapted to interlock with the second member. A tissue retaining device is also provided which comprises a mating member having a receiving portion formed thereon, said receiving portion having an inner surface and securing structure comprising a ring having an outer surface dimensioned and configured for insertion into said receiving surface to compress tissue between said outer surface of said ring and an inner surface of said mating member receiving portion.
