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. |

DETAILED DESCRIPTION In view of the foregoing, it is an advantage of the invention to provide surgical needles, retainers and surgical fasteners that permit surgeons to perform peripheral vascular and cardiovascular surgery with minimally invasive techniques, without the need to either tie knots or manage a trailing suture.
It is an advantage of the invention to provide surgical needles, retainers and fasteners useful in minimally invasive procedures to replace or bypass a diseased, occluded or injured artery quickly, safely, and reliably.
It is an advantage of the invention to provide surgical needles and retainers that form surgical fasteners useful in constructing an artery-to-graft anastomosis in the abdominal cavity, retroperitoneal space or chest.
It is an advantage of the invention to provide instruments and methods for precisely manipulating these needles and retainers, and for applying the fasteners by minimally invasive surgery.
It is an advantage of the invention to provide fasteners, instruments and methods that permit surgeons to perform minimally invasive surgery by employing many of the same suturing skills and techniques used in open surgery.
It is an advantage of the invention to provide surgical needles, retainers, fasteners and instruments capable of use in constructing other soft tissue anastomoses or joining other soft tissues together by minimally invasive techniques.
It is an advantage of the invention to provide surgical needles, retainers, fasteners and instruments that are also capable of use in traditional open surgery.
These and other advantages are achieved by providing a needle designed to permit surgeons to construct vascular and other anastomoses by minimally invasive surgery, while employing many of the same skills and techniques that are applicable to manipulating conventional suture needles and to constructing such anastomoses with conventional sutures.
In accordance with these and other advantages, embodiments of the present invention include a needle and a retainer that when joined together comprise a surgical fastener
