A fistula cleaning and repairing device comprises a device for cleaning a fistula and a device for repairing a fistula. Some versions of the device for cleaning a fistula comprise a rotary device with ah head configured to debride a fistula. Some versions of the device for cleaning comprise an abrasive catheter. Some versions of the device for cleaning comprise a plurality of abrasive beads. Some versions of the device for repairing a fistula comprise an implantable stent. Some versions of the device for repairing a fistula comprise an implantable mesh. Some versions of the device for repairing a fistula comprise a swab configured to deliver a medical fluid.

Fistula cleaning and repair device and method

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.

Methods and apparatus for delivering tissue treatment compositions to stapled tissue

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.

Instrument for applying therapeutic cells, with proximal portion for processing therapeutic cells

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.

Therapeutic cell applicator instrument with modular tips

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.
