Patent number: 5829662Abstract: A surgical stapler is provided which is insertable through an endoscopic tube to enable a surgeon to staple a hernia patch to tissue inside a body cavity. The endoscopic surgical stapler includes a staple cartridge pivotally mounted on the distal end of a support tube extending from a handle provided with an actuator mechanism for actuating a staple forming mechanism inside the staple cartridge to fasten staples to the tissue. The staple cartridge is adjustable to different angular orientations relative to the support tube. The staple actuator mechanism is operable to actuate the staple cartridge in any of the angular orientations. The support shaft is rotatable about its longitudinal axis relative to the handle to adjust the rotational orientation of the support shaft and the staple cartridge. The staple cartridge is rotatable about its longitudinal axis relative to the support shaft to adjust the rotational position of the staple cartridge relative to the support shaft.Type: GrantFiled: September 9, 1996Date of Patent: November 3, 1998Assignee: Ethicon, Inc.Inventors: Eugene David Allen, James J. Bedi, Gregory D. Bishop, Mark A. Burdorff, Sean P. Conlon, John A. Hibner, J. David Hughett, Mark S. Ortiz, Joseph Paraschac, Narinderjit Sambi, Thomas J. Sierocuk, Jack E. Smith

Patent number: 5346504Abstract: The present invention is directed towards an intraluminal manipulator which extends into a lumen and is operable to position and manipulate the tissue surrounding the lumen as necessary during a medical procedure. The manipulator includes a head, a handle and an interconnecting shaft. A pair of cables extend through the shaft and interconnect the head and handle. Movement of a trigger provided by the handle moves the head, which is formed by a series of articulated links, between generally straight and arched configurations. Movement of the trigger in one direction moves the head from a straightened to an arched configuration, while movement in an opposite direction moves the head from the arched to the straightened configuration. When placed in the straight configuration, the head is insertable into and removable from the lumen. When the head is in the arched configuration, it engages the walls surrounding and defining the lumen and can thereafter be used to manipulate the tissue.Type: GrantFiled: November 19, 1992Date of Patent: September 13, 1994Assignee: Ethicon, Inc.Inventors: Mark Ortiz, Joseph Paraschac
