Title:	Reduced-pressure treatment systems and methods employing debridement mechanisms
Abstract:	Reduced-pressure treatment systems and methods are disclosed that employ debridement mechanisms to remove unwanted tissue. In one instance, a reduced-pressure treatment system for treating a tissue site on a patient includes a manifold member for distributing reduced pressure to the tissue site, a support member for disposing proximate the tissue site and the manifold, and a debridement mechanism coupled to the support member. The debridement mechanism is for debriding the tissue site. The system further includes a sealing drape for placing over the tissue site and manifold member. The sealing drape is operable to form a fluid seal over the tissue site and manifold member. The system also includes a reduced-pressure subsystem for delivering a reduced pressure to the sealing drape. The system may further include a chemical-debridement subsystem. Other systems, manifolds, and methods are disclosed.

Application Number:	12/639,351
Patent Claims:	1. A reduced-pressure treatment system for debriding a tissue site on a patient, the system comprising: a manifold member formed from a porous material that contracts in response to reduced pressure; a support member coupled to the manifold member; a pincer including a first blade and a second blade, each having a proximal end coupled to the support member and a distal end for positioning at the tissue site, the distal end being moveable for debriding the tissue site in response to the manifold member when contracting; a sealing drape for placing over the tissue site and manifold member and operable to form a fluid seal over the tissue site for application of reduced pressure to the manifold member; and a reduced-pressure subsystem for delivering a reduced pressure through the sealing drape to the manifold; wherein the distal ends of the first blade and a second blade move between an open and closed position under the influence of the reduced pressure. 2. The system of claim 1, wherein the distal ends of the first and second blade extend towards each other. 3. The system of claim 1, further comprising a chemical-debridement subsystem for delivering a debriding chemical to the tissue site. 4. The system of claim 1, further comprising a chemical-debridement subsystem for delivering a debriding chemical to the tissue site, wherein the chemical-debridement subsystem comprises a debriding chemical reservoir in fluid communication with the sealing drape whereby the debriding chemical is delivered to the tissue site. 5. The system of claim 1, further comprising a chemical-debridement subsystem for delivering a debriding chemical to the tissue site, wherein the debriding chemical is one or more enzymes isolated from insect larvae. 6. The system of claim 1, further comprising a chemical-debridement subsystem for delivering a debriding chemical to the tissue site, wherein the debriding chemical is a chemical selected from the group consisting of: collagenase, ficin, pepsin, trypsin, chymotrypsin, papain and elastase.
