Abstract: 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.

Abstract: A dicing device dices tissue harvested from a patient. The dicing device comprises a grid cutting element and a tray to receive diced tissue. The dicing device may be integrated into an otherwise conventional biopsy device. The diced tissue specimens may be further processed, such as by being introduced into a self-expanding fistula plug creation and delivery system. The self-expanding fistula plug creation and delivery system comprises a sheet and a reinforcement tube. A scaffold material may be placed in the sheet, which may then be folded and reinforced, with the scaffold material being compressed in the sheet. The scaffold material may then be pushed into a catheter end. The catheter end may be inserted in a fistula. The scaffold material may then be flushed with a cell matrix that is based on the diced tissue to create a fistula plug, which may be left in the fistula.

Abstract: 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.
