Patent number: 6149658Abstract: A sutured staple, instrument and method are provided for constructing a graft-to-artery anastomosis and other soft tissue anastomoses, particularly by minimally invasive (or endoscopic) surgery. The sutured staple is comprised of a needle, pin, base and flange. The needle allows this surgical staple to be sewn through, for example, a graft and artery to be joined, and the pin, base and flange are formed to seal the graft and artery together between cooperating surfaces of the base and flange. The instrument holds the staple at its distal or working end, and controls in the handle allow application of the staple. The method employs the sutured staples and instrument to join soft tissues and to construct graft-to-artery anastomoses.Type: GrantFiled: January 9, 1997Date of Patent: November 21, 2000Assignee: Coalescent Surgical, Inc.Inventors: Barry N.

Patent number: 5879371Abstract: A surgical fastener in the form of a ferruled loop, instrument and method are provided for constructing a graft to artery anastomosis and other soft tissue anastomoses, particularly by minimally invasive (or endoscopic) surgery. The ferruled loop fastener is comprised of a needle, a suture and a ferrule. The needle and suture member allow this fastener to be sewn through, for example, a graft and artery to be joined. The ferrule member allows a ferruled loop to be formed without knotting the suture member, and that serves as a suture stitch to fasten the graft and artery together. The instrument holds the needle and ferrule at its distal end, and controls in the handle allow manipulation of the needle and controllable application of the fastener. The method employs the ferruled loop and instruments to join soft tissues and to construct graft to artery anastomoses.Type: GrantFiled: January 9, 1997Date of Patent: March 9, 1999Assignee: Elective Vascular Interventions, Inc.Inventors: Barry N.
