    摘要: 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.

    摘要: A seal assembly is provided which includes a housing and resilient first seal member associated with the housing. The first seal member is preferably a gasket having an aperture formed therein for receiving surgical instrumentation adapted to cooperate with a dilating means having an exterior face associated with the housing for dilating the aperture of the gasket. The first seal member and the dilating member are adapted for relative movement therebetween, the first seal member and the dilating member assuming a first position wherein the aperture of the first seal member is spaced from the dilating member and assuming a second position wherein the aperture of the first seal member is stretched around the exterior face of the dilating member. A flexible member may also be provided to help maintain a seal between the first seal member and an instrument inserted therethrough, in particular when the instrument is moved in a transverse direction.

    摘要: An implantable device for regulating blood flow through a blood vessel includes an elongated support. The support includes axially spaced apart first and second substantially annular support portions, and an x-shaped linking member linking the axially spaced apart portions to one another. The device also includes a valve membrane extending between the axially spaced apart support portions and having an upper portion, a lower portion and an intermediate portion. The valve membrane includes a first region and a second lower region. The first region is folded over the linking member for attachment and the second region is adjacent the first region and unattached to the linking member. The second region is movable between a first position to enable blood flow and a second position to inhibit blood flow.
