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
