Device for performing end-to-end anastomosis

摘要

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.

主权项

1. An anastomosis device, comprising:
a) a support housing having an interior chamber and having a longitudinal axis, said support housing having a compliant flexible section, and a plurality of suture needles mounted on an outer surface of said compliant flexible section, said plurality of suture needles being aligned with, and around, said longitudinal axis; b) an introducer including a circular disc section rigidly affixed to said support housing adjacent to an end of said compliant flexible section, said circular disc section having a diameter selected to match an interior diameter of an anatomical tubular structure undergoing an anastomosis process; and c) a deformation mechanism mounted in said interior chamber and configured such that when said introducer is seated in said anatomical tubular structure and said deformation mechanism is activated said deformation mechanism including a cam head section bears outwardly away from said longitudinal axis against an interior surface of said compliant flexible section to drive said plurality of suture needles radially outwards away from said longitudinal axis forcing said plurality of suture needles to pierce through a wall of said anatomical tubular structure simultaneously around a circumference of said anatomical tubular structure.
