A debridement extension including a proximal end and a distal end, with the proximal end being adapted for connection to both an irrigation source and a suction source. The debridement extension includes a fitting adjacent the proximal end which includes both an irrigation port and a suction port. An inner cannula and an outer cannula are both attached to the fitting of the debridement extension and are, respectively, in fluid communication with the irrigation port and the suction port. A debridement tip is affixed to the distal end of the debridement extension and is independently in fluid communication with both the irrigation path and the suction path formed by the inner and outer cannulas, respectively. The debridement tip includes a plurality of irrigation apertures in fluid communication with the irrigation path and spaced about the periphery of the irrigation tip as well as a plurality of suction apertures in fluid communication with the suction path and spaced about the periphery of the debridement tip. The inner and outer cannulas of the debridement extension are flexible so that the debridement extension can be readily inserted into a tract wound for debridement thereof. The debridement tip further includes a plurality of external longitudinal flutes.

An irrigation system contains a safety relief valve and a safety relief valve control valve. The safety relief valve control valve acts to modulate the operation of the safety relief valve when there is flow from an outflow port. By this mechanism high flow rates are accommodated without causing premature activation of the safety relief valve.

Processes for treating polymeric surfaces to produce smooth, durable, slippery coatings which are able to withstand the rigors of sterilization and, long term exposure to human blood and other bodily fluids without substantial loss of their slipperiness. An article or device suitable as a wound drainage device coated in accordance with the process described is also disclosed.
