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.

Patent number: 6951564Abstract: A site marker device and marker are provided. The site marker device includes a housing and a distally extending delivery tube. A pusher rod is movably positioned within the delivery tube to eject a marker from the distal end thereof. An elongated tubular body is positioned about the delivery tube. An actuator is provided to provide two stage advancement. During the first stage, the delivery tube and the pusher rod are advanced through the distal end of the elongated tubular body. During the second stage of advancement, the pusher rod is advanced independently of the delivery tube to eject a marker from the distal end thereof. The marker is formed from a shape memory material and has a circular or hoop configuration in the relaxed state.Type: GrantFiled: September 3, 2003Date of Patent: October 4, 2005Assignee: United States Surgical CorporationInventors: Felix Espositio, Frank J.

Patent number: 6681978Abstract: A surgical stapler is disclosed which includes a first body portion supporting an anvil plate defining a fastener forming surface, and a second body portion configured to releasably mate with the first body portion. A disposable loading unit is removably supported in the second body portion and includes a cartridge defining a plurality of slots, a plurality of surgical fasteners disposed in the slots, a plurality of ejectors positioned adjacent the surgical fasteners, and a wedged actuator configured to enter into and translate through the cartridge to sequentially interact with the ejectors. An elongated actuation member is mounted for longitudinal movement within the second body portion and is releasably engagable with the wedged actuator, whereby longitudinal movement of the actuation member causes the wedged actuator to interact with the ejectors, driving the surgical fasteners from the cartridge to be formed against the anvil plate.Type: GrantFiled: January 19, 2001Date of Patent: January 27, 2004Assignee: United States Surgical CorporationInventors: Robert J.
