Patent number: 10524854Abstract: A surgical instrument can comprise a first jaw and second jaw, wherein the first jaw is movable relative to the second jaw to capture tissue having a tissue thickness. A tissue cutting force monitor is configured to determine the tissue thickness of the captured tissue and communicate the tissue thickness to a controller, wherein the controller is configured to adjust the speed of a tissue-cutting element during a cutting portion of a firing stroke based on the tissue thickness communicated from the tissue cutting force monitor. The controller is configured to reduce the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thicker tissue thickness to the controller. The controller is configured to increase the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thinner tissue thickness to the controller.Type: GrantFiled: November 20, 2015Date of Patent: January 7, 2020Assignee: Ethicon LLCInventors: Scott A. Woodruff, Patrick A. Weizman, Gwendolyn P. Payne, Donna L. Korvick, David K. Norvell, Aron O. Zingman

Patent number: 8453906Abstract: An end-effector assembly configured to be attached to a surgical instrument. The end-effector assembly comprises a first jaw and a second jaw comprising a staple cavity. At least one of the first jaw and the second jaw is movable relative to the other jaw. The end-effector assembly comprises a staple removably positioned within the staple cavity and an electrically-conductive driver configured to move the staple between a first stored position in which the staple is at least partially positioned within the staple cavity and a second position in which the staple is at least partially deployed from the staple cavity into tissue positioned intermediate the first jaw and the second jaw. The staple comprises an electrode.Type: GrantFiled: July 14, 2010Date of Patent: June 4, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Zhifan F. Huang, Jason L.

Patent number: 8068895Abstract: An instrument for deploying a marker at a site within a patient may include an elongate cannula, an elongate pusher, and a marker disposed within the cannula. The cannula may have a tip at its distal end and a transverse opening. The pusher may be disposed within the cannula, and may be moved longitudinally within the cannula. The pusher may have a ramped distal end. The marker may be configured to exit the transverse opening upon urging by the ramped distal end of the pusher. In some versions, the tip of the cannula has a flat proximal face, and the marker has a recessed region that is configured to buckle in response to longitudinal compression, such that the marker will pop out of the cannula upon buckling. In other versions, the cannula has an external sheath, an open and curved distal end, or a leaf spring.Type: GrantFiled: February 25, 2008Date of Patent: November 29, 2011Assignee: Devicor Medical Products, Inc.Inventors: Trevor W.
