Patent number: 9724120Abstract: A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.Type: GrantFiled: December 17, 2013Date of Patent: August 8, 2017Assignee: Ethicon Endo-Surgery, LLCInventors: Craig N. Faller, Patrick A. Weizman, Jacqueline A. Anim, John W. Willis, Thomas C. Gallmeyer, Samardh Onukuri, John B. Schulte, Amy L. Marcotte, Sean P. Conlon, Jacob S Gee, Kevin L. Houser, Jeffrey L. Aldridge, Ryan M. Asher, Foster B. Stulen

Patent number: 9345477Abstract: A staple cartridge assembly for use with a surgical stapler. The assembly has a cartridge body having a support portion with a plurality of staple cavities with openings. There is also a plurality of staples, wherein at least a portion of each the staple is removably stored within the staple cavity. Each the staple is movable between an unfired position and a fired position, and is deformable between an unfired configuration and a fired configuration. The assembly also includes a compressible tissue thickness compensator configured to be captured within the staples. The compressible tissue thickness compensator at least partially covers the staple cavity openings. The compressed tissue thickness compensator is configured to assume different compressed heights within different the staples. The compressible tissue thickness compensator comprising a lyophilized foam having a hemostatic agent embedded therein.Type: GrantFiled: June 25, 2012Date of Patent: May 24, 2016Assignee: Ethicon Endo-Surgery, LLCInventors: Jacqueline A. Anim, Samardh Onukuri, Anthony Silvestri, Jr., Frederick E. Shelton, IV, Michael F. Clem, Tamara S. Vetro-Widenhouse

Patent number: 7762308Abstract: Techniques for forming cast parts for medical devices suitable for contact with internal regions of patients are described herein. Such parts can be small in scale (e.g., having a major axis less than 0.3 inches, and/or a minor axis less than about 0.08 inches), and can be formed from metals that have a high melting point and high reactivity with environmental components or mold surfaces, such as stainless steel and titanium alloys. Such techniques can include injecting molten metal into the sprue of a mold tree such that the side runners are backfilled after the molten metal impacts a closed end of the sprue. Side runners can be oriented in particular directions and positions to promote backfilling. As well, flask temperatures and the use of surfactants can also promote cast part formation, hindering the formation of surface defects.Type: GrantFiled: December 3, 2007Date of Patent: July 27, 2010Assignee: Ethicon Endo-Surgery, Inc.Inventors: William A. Crawford, Tracy J. Potter, Donald F. Heaney, Brain S. DeForce, Samardh Onukuri

Publication number: 20060052824Abstract: The present invention provides a surgical implant which can be made of a metal that corrodes while implanted in tissue. The implant can include an electrical insulator, such as in the form of a film, coating, or surface layer, for reducing the conductivity of the implant. The surgical implant can include a electrical insulator for reducing the conductivity of the implant. By way of example, the surgical implant can be in the form of a staple, and insulator can be in the form of an anodized surface layer.Type: ApplicationFiled: October 31, 2005Publication date: March 9, 2006Inventors: Mark Ransick, Samardh Onukuri, Thomas Huitema, Michael Murray, Darrel Powell
