Abstract
Abstract A surgical instrument for anastomosis of first and second blood vessels is provided having a handle and a body portion extending distally from the handle. A collet is mounted adjacent a distal end portion of the body portion and defines a passage therethrough for the reception of an end of a first blood vessel. A plurality of surgical fasteners are releasably supported by the collet and radially oriented about the distal end thereof. An anvil is mounted adjacent of the collet. The anvil and collet are relatively slidable in response to actuation of the handle to simultaneously deform then release the surgical fasteners.

A surgical instrument for anastomosis of first
and second blood vessels, which comprises: a) a handle; b) a body portion extending distally from
the handle; c) a fastener support positioned adjacent
a distal end portion of the body portion, the support
defining a passage therethrough for the reception of an end
of a first blood vessel and configured and dimensioned to
releasably support a plurality of surgical fasteners; and d) a camming member mounted proximal of
the support, the camming member and support being
relatively slidable in response to actuation of the handle
to simultaneously deform the surgical fasteners.
