DEVICES AND METHODS FOR PERFORMING VASCULAR ANASTOMOSIS

摘要

The present invention is devices, and methods for performing vascular anastomosis. A needle passer (100) is used to pass one or more needles through tissue to thread one or more lengths of suture (112) through the tissue. The needle passer (100) is operable using one hand, and includes a handle (102) supporting a shaft assembly (104) carrying first, and second sets of needles (110, 114) connected by lengths of suture (112). An actuator assembly (106) uncovers the first set of needles (110), moves them into a radially extended portion, and passes them through tissue. The needle passer (100) may be pistol shaped with a trigger (108). A delivery device (300) is used to deliver a vascular conduit (c) adapted tp be secured to body tissue. A delivery device includes a shaft (302) and a collar (304). A sealing element (306) may be positioned on the collar beneath the end of the conduit.
