摘要:
A treatment system comprises an outer sheath and an end effector. The end effector has a plurality of cutting features, at least a portion of which are configured to debride a tissue surface when the end effector is actuated. The cutting features may also be configured to harvest tissue. A medical fluid reservoir is in fluid communication with the end effector, such that the end effector may deliver a medical fluid to a target site such as a fistula. The medical fluid may include harvested tissue cells and a scaffold material. A vacuum cannula may be positioned coaxially within the interior cavity of the end effector, and an RF probe may be positioned co-axially within the interior cavity of the vacuum cannula. The vacuum cannula and RF probe may be used together to seal a fistula in which medical fluid has been dispensed.
