Patent ID: 7682368

Claim:
A surgical tool used to connect a graft vessel to a target vessel, comprising: a tissue effector operationally connectable to a source of pressurized gas; a handle connected to said tissue effector, wherein said handle includes a trigger; at least one anastomotic connector deployable from said tissue effector; and a fluid-driven actuator connected to said a source of pressurized gas; wherein said fluid-driven actuator includes a control member operationally connected to said trigger and a first chamber within which said control member is slidable, wherein said chamber includes a wall; further comprising at least one sealing element that substantially seals against said control member and said wall of said first chamber, wherein said at least one sealing element is slidable with said control member; wherein said fluid-driven actuator includes a clamping member and a second chamber within which said clamping member is movable, wherein said first chamber and said second chamber are interconnected, and a first cable fixed to said clamping member, said first cable extending to said tissue effector, wherein motion of said control member causes said gas to move said clamping member proximally, which in turn causes proximal motion of said first cable that moves said tissue effector from an open position to a closed position in which the graft vessel is clamped to the target vessel; and wherein said fluid-driven actuator includes a firing member and a third chamber within which said firing member is movable, wherein said third chamber is interconnected with at least one of said first chamber and said second chamber, and a second cable fixed to said firing member, said second cable extending to said tissue effector; wherein further motion of said control member causes said gas to move said firing member proximally, which in turn causes proximal motion of said second cable that deploys at least one said anastomotic connector.
