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.

1. A reduced-pressure treatment system for treating a tissue site on a patient, the system comprising: a manifold member adapted to contract in response to application of reduced pressure to the tissue site;a support member mechanically coupled to the manifold member;a debridement arm having a proximal end and a distal end, the proximal end operatively coupled to the support member and the distal end having a face including an edge to debride the tissue site, wherein the debridement arm is deformable to drive the edge of the face against the undesired tissue in response to contraction of the manifold member when induced by the application of reduced pressure;a sealing drape for placing over the tissue site and manifold member and operable to form a fluid seal over the tissue site and the manifold member; anda source of reduced-pressure for delivering a reduced pressure through the sealing drape to the manifold member. 2. The system of claim 1, further comprising a chemical-debridement subsystem for delivering a debriding chemical to the tissue site. 3. 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. 4. 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. 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 a chemical selected from the group consisting of: collagenase, ficin, pepsin, trypsin, chymotrypsin, papain and elastase. 6. A dressing for treating a tissue site on a patient, the manifold member comprising: a manifold material adapted to contract in response to application of reduced pressure from a source of reduced pressure to the tissue site;a support member mechanically coupled to the manifold material;a debridement arm having a proximal end and a distal end, the proximal end operatively coupled to the support member and the distal end having a face including an edge to debride the tissue site in response to contraction of the manifold material when induced by the application of reduced pressure, wherein the debridement arm is deformable to drive the edge of the face against the undesired tissue in response to contraction of the manifold material; anda sealing drape for placing over the tissue site and manifold material and operable to form a fluid seal over the tissue site and the manifold material for providing reduced pressure to the manifold material and the support member. 7. A method for treating a tissue site on a patient using the dressing of claim 6, the method comprising: positioning the manifold material within the tissue site so that the distal end of the debridement arm is positioned adjacent the undesired tissue of the tissue site;disposing the sealing drape over the manifold material to form a fluid seal over the tissue site and the manifold material; andproviding a reduced pressure to the manifold material whereby the debridement arm deforms to drive the edge of the face against the undesired tissue to debride the tissue site in response to contraction of the manifold member. 8. The method of claim 7, further comprising introducing a debriding chemical to the tissue site. 9. The method of claim 7, further comprising introducing a debriding chemical to the tissue site and wherein the debriding chemical is one or more enzymes isolated from insect larvae. 10. The method of claim 7, further comprising introducing a debriding chemical to the tissue site, wherein the debriding chemical is one or more enzymes isolated from insect larvae, and wherein the debriding chemical is a chemical selected from the group consisting of: collagenase, ficin, pepsin, trypsin, chymotrypsin, papain and elastase. 11. The method of claim 7, further comprising introducing a debriding chemical to the tissue site, and flushing the tissue site. 12. The system of claim 11, wherein the debridement arm deforms in response to a compressive force of the manifold member contracting causing the distal end of the debridement arm to move from a neutral position to a compressed position and drive the edge of the face against the undesired tissue. 13. The system of claim 12, wherein the debridement arm forms a first angle with respect to the manifold member when in the neutral position and a second angle with respect to the manifold member when in the compressed position, and wherein the first angle is greater than the second angle. 14. The manifold member of claim 6, wherein the debridement arm deforms in response to a compressive force of the manifold material contracting causing the distal end of the debridement arm to move from a neutral position to a compressed position and drive the edge of the face against the undesired tissue. 15. The manifold member of claim 14, wherein the debridement implement forms a first angle with respect to the manifold material when in the neutral position and a second angle with respect to the manifold material when in the compressed position, and wherein the first angle is greater than the second angle.
