    摘要： A control handle for a full thickness resection device is disclosed. In an embodiment for the control handle of the present invention, the control handle includes a body and a staple firing assembly coupled to the body. The staple firing assembly includes a rotatable staple firing ring, a worm gear assembly rotatably engaged with the staple firing ring, and a flexible drive shaft coupled to the worm gear assembly. In an embodiment for a method of the present invention, a method for actuating a full thickness resection device is provided. The method includes the steps of rotating a staple firing ring in a first direction and actuating a worm gear assembly in a first operative mode in response to the rotation of the staple firing ring in the first direction, the worm gear assembly is coupled to the staple firing ring. A flexible drive shaft is rotated in the first direction, the flexible drive shaft being coupled to the worm gear assembly, and torsional energy is stored in the flexible drive shaft during rotation of the flexible drive shaft in the first direction. The worm gear assembly is actuated in a second operative mode and a release rate of the stored torsional energy in the flexible drive shaft is controlled by the worm gear assembly. The flexible drive shaft is rotated in a second direction.

    摘要： A control mechanism for a resectioning device, comprises a first actuator coupled to a flexible drive shaft for actuating a first mechanism when operated in a first direction and for actuating, when operated in a second direction, a second mechanism and a first lockout mechanism coupled to the first actuator for preventing actuation of the first actuator in the second direction before a predetermined amount of actuation in the first direction has been completed. Furthermore, mechanisms are provided to control the release during operation in a second direction of torsional energy stored in a flexible drive shaft during operation in a first direction.

    摘要： 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
