Abstract
Herein is provided an anastomosis device which includes a cylindrical support housing having a tapered section being formed of a plurality of compliant fingers integrally formed around the circumference of an end of the cylindrical section which can flex at their connection point to the cylindrical section. Each compliant finger holds a suture needle. The device includes a push rod having a cam head at one end of the rod section. The cam head is located adjacent to the tapered portion. In operation the anastomosis device is aligned with the anatomical tubular structure undergoing an anastomosis process. When a back end of the push rod is pushed towards the tapered section of the support housing, the cam head section bears against an inner surface causing each compliant finger to flex radially outwards forcing the suture needles to simultaneously pierce the wall of the anatomical tubular structure.
