ABSTRACT:
The stapling device includes an anvil tube with a plurality of radially oriented and outwardly movable segmented arms and associated anvils mounted on the distal end of the segmented arms which are movable within an insertion space. The anvils are conically shaped which enable insertion into a vascular lumen over a guide wire. A staple pusher tube mounting staples at its distal end is mounted externally of the insertion tube. Prior to a stapling procedure, the distal end of the graft is attached to the anvils with a peel-off glue. When the segmented arms are pushed out into a stapling position inside a blood vessel, the anvils open outwardly due to elastic recoil of the segmented arms. The anvils are then stabilized in the stapling position by a centrally inserted expansion rod which is wedged into the core space of the segmented arms. The anvils are pulled back against the vascular wall and the staple pusher is pushed towards the anvils while advancing the staple wires which penetrate the graft and vascular wall and are bent over the anvil to anastomose the graft onto the vascular wall. Following the stapling procedure, the prosthesis is peeled off from the anvils, which are retracted into their folded position, and the device is removed from the patient.
