Patent number: 8641641Abstract: A tissue harvesting and processing apparatus comprises a body and a distally extending needle. The needle includes an aperture configured to receive tissue. A tissue cutting member is movable relative to the needle to sever a specimen from tissue protruding through the aperture. A tissue processor is operable to mince tissue severed by the tissue cutting member. The minced tissue may be mixed with a medical fluid component contained in a reservoir. The medical fluid mixture may be expelled through an applier tip coupled with the body. The tissue processor may comprise a mincing die such that tissue specimens are minced upon being extruded through the mincing die. The tissue processor may comprise a blade that cooperates with a sliding press. The tissue processor may comprise auger blade sections that cooperate with inwardly extending pins. A mixing piston may mix the minced tissue with the medical fluid component.Type: GrantFiled: May 11, 2010Date of Patent: February 4, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: Michael D. Cronin, Patrick D. Dugan, Shelby L. Cook Kornbluth, Donna L. Korvick, Rebecca J. Mollere, Jerome R. Morgan, Shailendra K. Parihar, John B. Schulte, Richard W. Timm

Patent number: 8491526Abstract: A surgical device comprises a housing, a bioprocessing module, an end effector, and a pumping device. The bioprocessing module comprises media reservoirs, fluid conduits in communication with the reservoirs, and a port through which media is expelled. The end effector is configured for insertion into a lumen and delivering a tissue repair composition into that lumen. The end effector has at least one fluid conduit extending therethrough and at least one orifice in communication with the fluid conduit. The fluid conduit in the first end effector is in fluid communication with the port on the bioprocessing module.

Patent number: 8465515Abstract: Methods and devices are provided for performing surgical procedures using tissue retractors. In general, the methods and devices allow a surgeon to use a retractor to capture a large or small amount of tissue in a fabric and to move the fabric to relocate the tissue to one or more convenient locations during the procedure. The flexible nature of the fabric can allow the fabric to be moveable between an open position, in which the fabric can support tissue, and a closed position, in which the fabric can be folded, rolled, or otherwise compressed in size and fit through a port, such as a trocar or an incision in a tissue wall. Furthermore, the position of the fabric and thus the tissue held in the fabric can be adjusted and readjusted by pushing or pulling one or more grasping elements coupled to the fabric.Type: GrantFiled: August 29, 2007Date of Patent: June 18, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Daniel W. Drew, Michael D. Cronin

Patent number: 8464925Abstract: A surgical stapler includes first and second tissue clamping members and a reservoir configured to hold a tissue treatment composition. The first tissue clamping member is configured to receive a plurality of staples. The second tissue clamping member comprises an anvil configured to form the staples. The reservoir may be provided in a handle portion of the surgical stapler, and a fluid conduit may be used to communicate the tissue treatment composition from the reservoir. An end effector lumen may selectively communicate with the fluid conduit. The lumen may also be in communication with openings to further communicate the tissue treatment composition to tissue or to a scaffold material positioned adjacent to tissue. A reservoir may alternatively be provided in one of the clamping members. A knife member may pierce a housing defining the reservoir, and a resilient member may then urge a tissue treatment composition from the housing.Type: GrantFiled: May 11, 2010Date of Patent: June 18, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Joanne Hull, Wells D.
