Abstract: 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.

Abstract: A brush debridement tip for use with hand-held wound debridement devices. The brush debridement tip of the present invention provides concurrent irrigation and suction to the area to be debrided and includes a plurality of bristles extending therefrom. The plurality of bristles have varying lengths to advantageously allow for mechanical debridement of, e.g., resected or otherwise formed having irregular shapes. The brush debridement tip further includes an elongate aperture allowing passage of a fan spray of irrigation fluid therethrough.

Abstract: A soft contact debridement tip for use with hand-held wound debridement devices. The soft contact debridement tip of the present invention provides concurrent irrigation and suction to the area to be debrided. The soft contact debridement tip includes a foam end having an opening for providing irrigation and suction to the area to be debrided. Advantageously, the foam end of the present invention facilitates the removal of excess fluid at the debridement site, and at the same time alleviates pain and discomfort associated with wound debridement. The soft contact tip of the present invention is adapted for single use, and is easily attached and detached from a hand-held debridement device.

Abstract: 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.

Abstract: 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.
