Patent number: 8512359Abstract: A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon. As the wedge is moved proximally from the distal end of the second jaw to the proximal end, the wedge pushes a plurality of staples against a plurality of opposing staple guides disposed in the first jaw in order to staple a section of tissue while cutting the section of tissue.Type: GrantFiled: August 11, 2011Date of Patent: August 20, 2013Assignee: Covidien LPInventors: Michael P.

Patent number: 8008598Abstract: A system and method for forming a staple pocket, e.g., on the anvil portion of a surgical stapler device. A laser-machining system may include a laser-emitting device that is configured to emit a laser beam or beams for forming staple pockets on the anvil of a surgical stapler. The staple pockets of an anvil may be formed successively or simultaneously. The anvil of the surgical stapler is mounted in a mounting mechanism so as to control its movement, and the laser-emitting device is controlled by a control module, which may control any aspect of the laser-machining operation, e.g., the intensity of the laser beam, the movement of the laser-emitting device relative to the anvil, etc. The control module may be a processor that includes software that provides instructions for the operation of the control module, and may be programmable by a user for inputting parameters, e.g., shape, arrangement, etc., corresponding to the staple pockets.Type: GrantFiled: July 27, 2006Date of Patent: August 30, 2011Assignee: Tyco Healthcare Group LPInventors: Michael P.
