Abstract

The anastomosis device according to the present invention is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes a frame for receiving and holding the end of a graft vessel in an everted position and first and second spreading members configured to be inserted into an opening in the target vessel. The first and second spreading members are arranged substantially in a plane for insertion into an opening in a target vessel, and are moved away from one another to capture the edges of the opening in the target vessel securing the graft vessel to the target vessel. One version of the anastomosis device includes a plurality of linkages arranged in two rows for grasping opposite sides of an opening in the target vessel. A portion of the linkages fold outward to trap vessel walls on opposite sides of the opening in the target vessel. The anastomosis devices greatly increases the speed with which anastomosis can be performed over known suturing methods.
