Mechanical anastomosis system for hollow structures
First Claim
1. A device for use in a system for making intraluminal anastomoses between hollow structures by mechanical means, comprising an annular or tubular element separate from the hollow structures and including joining means formed circumferentially thereon for joining the abutting walls of the hollow structures together, wherein said annular element is permanently deformable from a first diameter in the starting position to a second, larger diameter in the joining position, and wherein said joining means comprises a number of pin-shaped elements which are circumferentially provided on said annular element, and which are movable or deformable between a starting position and a joining position in order to hold the abutting walls together.

Abstract
A system for making anastomoses between hollow structures by mechanical means is provided with a device in the shape of an annular or tubular element comprising circumferentially provided means, such as pin-shaped elements, for joining the abutting walls of the hollow structures together. An applicator is intended for moving said annular or tubular element in position and activating the joining means thereof, so as to make the anastomosis. Possibly, intraluminal joining means can be inserted without using an annular or tubular element.
