International Classification:

A61B 18/18
A61B 17/08

US Classification:

606 51, 606151

Abstract:

An electrosurgical stapling instrument includes an end effector capable of applying bipolar RF energy into tissue. The end effector has a first pole electrode and a second pole electrode for forming an RF contact circuit with tissue. At least one of the electrodes may have a dielectric coating thereon to create a RF circuit with tissue. The dielectric coating can cover one of the electrodes to create a capacitive coupling circuit with tissue, or can have at least one open passageway extending through the dielectric coating to enable tissue contact with the electrode and the passage of RF energy therethrough. The dielectric coating on the electrode can be masked to create passageways through the dielectric, or the dielectric coating can be locally removed with a variety of techniques to form passageways. The dielectric coating may provide a barrier to prevent shorting between the dielectrically coated electrode and a conductive fastener embedded within tissue. Alternately, a cartridge coating can be used to reduce an electric surface sheet charge on the cartridge thermoplastic that can occur during the application of RF energy to tissue.

A61M 5/00

US Classification:

604 82, 604191, 604128, 604187

Abstract:

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. The pumping device is operable to urge a tissue repair composition comprising at least a portion of the contents of the media reservoirs through the fluid conduit of the first end effector such that the tissue repair composition is expelled from the at least one orifice.

US Classification:

606 52, 606 51, 606206, 606207, 606208

Abstract:

A surgical instrument comprising an end effector, the end effector comprising first and second opposing jaw members, wherein at least one of the first and second jaw members are moveable such that the first and second jaw members are transitionable between open and closed positions. The first jaw member may comprise a permanent magnet. The second jaw member may also comprise a magnet (e. g. , permanent or soft). The magnetic motive force between the magnets of the first and second jaw members may attract each other to thereby reduce the external force required to transition the first and second jaw members to the closed position. In addition, the magnets may be configured to repeal each other to thereby aid in opening the jaw members.

US Classification:

2271791, 623 2372

Abstract:

A surgical stapler includes first and second tissue clamping members and a knife member. 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. A tissue treatment member is positionable between the first and second tissue clamping members. The tissue treatment member comprises a rupturable pouch or baffle that is configured to receive a medical fluid including at least one tissue cell. The tissue treatment member may have a spiral shape, an annular disc shape, or an elongate sleeve shape. The tissue treatment member may also include outwardly extending tabs. The tissue treatment member may also include an injection port. In use, the staples and/or the knife pierce the tissue treatment member to release at least a portion of the medical fluid held by the tissue treatment member.
