A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis.

Device for engaging tissue having a preexisting opening

A device for engaging tissue having a preexisting opening includes a generally annular-shaped ring having a width disposed about a longitudinal axis, and at least two staple members extending from the ring. Each of the at least two staple members have a thickness and at least a distal portion formed of an elastic material. The distal portions of the staple members have a first configuration, where the distal portions are separated by a first distance and wherein the distal portions are substantially parallel to the longitudinal axis, and a second configuration, where the distal portions are separated by a second distance, the second distance being less than the first distance, and the at least two staple members engage tissue surrounding the preexisting opening. The annular-shaped ring has a width that is greater than the thickness of the at least two staple members.

A surgical fastener system includes a plurality of fasteners having a throughbore with an internally threaded portion. The fasteners may engage with a threaded mandrel that passes through the throughbore of the fasteners. A rotator may rotate the fasteners relative to the mandrel to move at least one of the fasteners along the mandrel, e.g., along the mandrel's longitudinal axis. A distal end of the mandrel may be inserted into a material, such as a tissue, prosthetic or other, and a fastener may be deployed from the distal end of the mandrel while the distal end is positioned in the material. The throughbore of the fasteners may include a threaded portion and an unthreaded portion, may include an angled face or other feature to aid in fastener deployment and/or have curved depressions in the head portion.
