Abstract
A surgical fastener in the form of a pinned retainer, 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 pinned retainer fastener is comprised of a needle and a retainer. The needle has a base, shaft and tip that allow this member to be sewn through, for example, a graft and artery to be joined. The retainer has an aperture to receive and securely engage the needle shaft to seal the graft and artery together between cooperating surfaces of the needle base and retainer. The instrument holds the needle and retainer at its distal or working end, and controls in the handle allow application of the retainer. The method employs the pinned retainer fasteners and instrument to join soft tissues and to construct graft to artery anastomoses.
