    摘要: The present invention provides medical devices and methods for: suturing tissue by proximally drawing sutures through a tissue layer in the proximity of an aperture; suturing vascular tissue while maintaining adequate perfusion or hemostasis, or both; anastomosing a graft to an aperture in a vessel wall while maintaining hemostasis at the anastomosis with physiological flow and/or pressure in the vessel lumen; punching and removing tissue to form an aperture in a vessel wall while maintaining hemostasis at the aperture with physiological flow and/or pressure in the vessel lumen; automatically and repeatably placing suture thread through vessel wall tissue surrounding an aperture in the vessel wall in a suture pattern that is useful for anastomosing a tubular graft to the aperture; and, deploying a suture with one end extending through the tissue that surrounds a punched aperture in a vessel wall and the opposite suture end extending radially through a tubular graft wall adjacent an open end of the graft, such that a vessel anastomosis may be rapidly and repeatably performed in a CABG procedure even while the vessel is under physiological flow.

    摘要: The present invention provides devices and methods for suturing a tissue layer having two sides with a suture by releasably retaining at least a portion of the suture in a stationary position on one side of the tissue layer. The portion of the suture is retrieved through the tissue layer from the opposite side whereby the suture is drawn from one side to the opposite side. Devices and methods for suturing the wall of a tubular graft having two sides is also provided using a suture by releasably retaining at least a portion of the suture on one side of the wall. The portion of the length of suture is retrieved through the wall of the graft to the opposite side of the wall. A graft anastomosis assembly provided herein sutures a tubular graft about an aperture in a tissue wall using a suture, a tissue suturing and graft suturing devices. Fastener types other than sutures are useful with the present invention whereby a first fastener portion is releasably retained in a stationary position on one side of a tissue layer while a second fastener portion is driven through the tissue layer from the opposite side and securely engages the two portions together.

    摘要: A surgical device for reinforcing the pericardial sac surrounding the heart to assist in the treatment of congestive heart failure includes an enclosure having an interior and an exterior. The interior surface limits adhesions or accepts ingrowth with the myocardial tissue of the epicardium. The exterior surface is adapted to adhere to or otherwise attach to the pericardium to provide reinforcement.
