Abstract: Devices for delivering and deploying a prosthesis are disclosed and comprise a sheath, a prosthesis disposed within a distal end portion of the sheath, and a wire having a first end coupled to the prosthesis and a second end coupled to the sheath. A body portion of the wire comprises a slack in the wire, and the sheath, prosthesis, and wire are configured so that a proximal movement of the sheath relative to the prosthesis reduces the slack in the wire, and a subsequent proximal movement of the sheath relative to the prosthesis decouples the wire from the prosthesis. Additional devices, systems, and methods are disclosed.

Abstract: The present invention relates to a prosthesis delivery device and to a handle assembly located at the distal end of the delivery device. The handle assembly has a main handle and a nut disposed on the main handle. The nut has a first configuration in which the nut is engaged with the outer surface of the main handle and a second configuration in which the nut is disengaged from the outer surface of the main handle. Disengaging the nut from the main handle facilitates quick sheath retraction and deployment of at least the distal end of the prosthesis as well as recapturing the proximal end of the device within the sheath.

Abstract: The present invention relates to a deployment handle for a prosthesis delivery device and to a delivery device including such a handle. The handle assembly facilitates the controlled release of a prosthesis from the delivery device, while ensuring that various deployment steps are performed in a particular sequential order. The handle assembly comprises a main handle and a second handle which is rotatably and/or longitudinally moveable relative to the main handle. The second handle has an initial position on the main handle such that it prevents access to, and premature manipulation of, a proximal stent release mechanism, until the stent graft has been at least partially unsheathed.

Abstract: A device is provided for closing a wound, such as a percutaneous access site. The device is inserted into the wound, and a helically shaped pusher is actuated to penetrate a wall of the wound. The pusher extends a suture through the tissue wall. After the suture is extending through the tissue wall, the pusher is retracted out of the tissue, while the suture remains extending through the tissue. The suture may then be used to close the wound.
