Patent number: 9492170Abstract: A modular end effector delivers a therapeutic agent onto tissue that has been severed and/or stapled. The end effector is removably attached to a device. The device applies force to a piston of the end effector. The force causes a distal movement of a piston along a wall disposed within the end effector. The piston engages with agents stored on opposite sides of the wall, moving the agents distally to a mixture space. The agents are mixed in the mixture space and expelled through a tip. Staples may be embedded in or disposed below a foam block, which is disposed within a staple cartridge. Via an endoscopic stapling device, coated staples are driven through tissue while interacting with another agent on the device or the cartridge. The interaction forms a tissue restoring material that is applied onto the tissue.Type: GrantFiled: August 10, 2011Date of Patent: November 15, 2016Assignee: Ethicon Endo-Surgery, Inc.Inventors: Brian W. Bear, Thu Anh Le, Thomas W. Lytle, IV, Mark D. Overmyer, Michael Setser, Bret W. Smith, Joseph Zavatsky, Kreena Modi

Publication number: 20130075447Abstract: A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a buttress material stored in one or both of the anvil or cartridge. The material is releasable onto severed tissue via a firing bar severing the buttress material in response to the longitudinal closing motion.Type: ApplicationFiled: September 22, 2011Publication date: March 28, 2013Inventors: William B. Weisenburgh, II, Craig S. Smith, Gregory B. Blair, Zhifan F. Huang, Douglas B. Hoffman, Kristi S. Geier, Bret W. Smith, Thomas W. Lytle, IV, Mark D. Overmyer, Brian W. Bear, Michael E.

Patent number: 7232455Abstract: A suture anchor is described which in one form may be easily fabricated from extruded material by angular cuts and bore holes which provide an offset pulling force to the suture. In an alternate and preferred embodiment the suture anchor is injection molded having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole. Novel application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument.Type: GrantFiled: May 26, 2004Date of Patent: June 19, 2007Assignee: DePuy Mitek, Inc.Inventors: Jack S. Pedlick, Thu Anh Le, John DiGiovanni, Dennis D. Jamiolkowski, Mark J. Suseck

Patent number: RE36289Abstract: A suture anchor device having an anchor member with outwardly extending wing members and an actuating wedge member. The suture anchor device is inserted into a bore hole in a bone as part of an orthopedic surgical procedure wherein soft tissue such as a tendon or ligament is attached to the surface of the bone. The wing members are spread outwardly by the wedge member to lock the suture anchor device in the bone. The suture anchor has similar utility in soft tissue applications.Type: GrantFiled: June 20, 1997Date of Patent: August 31, 1999Assignee: Ethicon, Inc.Inventors: Thu Anh Le, Sung Sok Yi, William Zwaskis, Jack S.
