Patent number: 7891533Abstract: An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.Type: GrantFiled: November 12, 2008Date of Patent: February 22, 2011Assignee: Tyco Healthcare Group LPInventors: David T Green, Keith Ratcliff, Keith Milliam, Henry R. Sienkiewicz, Mitchell J. Palmer, Graham W. Bryan

Patent number: 6053390Abstract: A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod. The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod. An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site. The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.Type: GrantFiled: May 10, 1999Date of Patent: April 25, 2000Assignee: United States SurgicalInventors: David T. Green, Henry Bolanos, Henry R. Sienkiewicz, Patrick Leahy

Patent number: 5860987Abstract: A surgical retractor device for manipulating organs during an endoscopic or laparoscopic surgical procedure. The retractor device includes a loop of material at a distal end of the instrument which is extendable and retractable from the elongated body portion of the instrument. The loop of material may be detached to be wrapped about an organ and reattached to secure the organ. Once the organ is secured, the loop of material may be retracted into the body portion of the instrument to manipulate the organ.Type: GrantFiled: December 10, 1996Date of Patent: January 19, 1999Assignee: United States Surgical CorporationInventors: Keith Ratcliff, Keith L.

Patent number: 5803902Abstract: A surgical retractor is disclosed having a handle portion, an elongated body portion extending distally from the handle portion and including an outer tube, a stabilizing member extending from a distal end of the outer tube and a pair of resilient bands pivotably connected to a distal end portion of the stabilizing member. An actuation mechanism is provided which is associated with the handle portion and the resilient bands for moving the bands between open and closed position. The surgical retractor further includes a sheath dimensioned to receive at least a portion of the stabilizing member and the bands. A surgical kit is also provided having a package configured to receive a surgical instrument, a base member for sealing the package, a surgical instrument having proximal and distal ends and having a mechanism for performing a surgical procedure located at the distal end, and a static barrier for enclosing the mechanism of the surgical retractor.Type: GrantFiled: September 20, 1996Date of Patent: September 8, 1998Assignee: United States Surgical CorporationInventors: Henry R.

Patent number: 5700275Abstract: A surgical instrument is provided having a housing defining a longitudinal axis. A handle is operably conected to the housing and defines a longitudinal axis angularly disposed relative to the longitudinal axis of the housing. A fixed support is attached to the housing and defines a longitudinal axis angularly disposed relative to the longitudinal axis of the housing. The fixed support is radially offset with respect to the handle. A body portion extends distally from the housing, and a tool assembly operably associated with a distal end portion of the body portion is remotely actuable by the handle.Type: GrantFiled: April 25, 1996Date of Patent: December 23, 1997Assignee: United States Surgical CorporationInventors: Mace H. Bell, Henry R. Sienkiewicz
