Abstract

According to an illustrative embodiment a method to promote healing of a wound is provided comprising contacting the wound with a biologically active composition comprising a lipoic acid derivative and gelatin. In another embodiment a topical composition is provided, which can be formulated as a homogenous mixture, such as a spray, mist, aerosol, lotion, cream, solution, oil, gel, ointment, paste, emulsion or suspension or applied on a carrier material, such as a bandage, gauze, foam, sponge, hydrogel, hydrocolloid, hydrofiber, occlusive dressing, adhesive composition or scaffold. Methods for producing such a topical composition and carrier material with the topical composition applied thereto are also disclosed.

Claims (15)

1. A system for treating a wound at a tissue site, comprising:

a pressure source to supply reduced pressure;

wound dressing in fluid communication with said pressure source to distribute reduced pressure to the wound, said wound dressing having a first portion contacting the wound and a second portion;

a lipoic acid derivative and a sacrificial proteolytic enzyme applied to the second portion of said wound dressing; and

a drape adapted to cover said wound dressing and the wound to provide a sealed space for applying the reduced pressure to the wound.

2. The system of claim 1 , wherein the first portion of said wound dressing is a scaffold.

3. The system of claim 2 , wherein the lipoic acid derivative and the sacrificial proteolytic enzyme are applied to the scaffold.

4. The system of claim 1 , wherein the wound dressing further comprises a scaffold.

5. The system of claim 4 , wherein the scaffold is comprised of polyurethane or collagen.

6. The system of claim 4 , wherein the lipoic acid derivative and the sacrificial proteolytic enzyme are applied to the scaffold.

7. The system of claim 1 , wherein the lipoic acid derivative and the sacrificial proteolytic enzyme are combine in a homogenous mixture.

8. The system of claim 7 , wherein the homogenous mixture is applied to both the first portion and the second portion of said wound dressing.

9. The system of claim 7 , wherein the homogenous mixture is applied to the surface of said wound dressing.

10. The system of claim 7 , wherein the homogenous mixture is applied to internal portions of said wound dressing.
