Abstract

System for enhancing the optical transparency of biological tissue covered by a surface permeability barrier of tissue, involving the delivery of a clarifying agent to the target biological tissue to alter the attenuation characteristics of the target biological tissue.

Claims

1. A system for changing optical properties of biological tissues, the system comprising:

a) means of topical dispensing of a chemical enhancer or carrier agent for transdermal drug delivery; and

b) a clarifying agent delivered topically that alters the optical properties of tissue prior to an optical treatment of the skin.

2. The system of claim 1, wherein the changing of the biological tissue is performed in-vivo, in-vitro, or ex-vivo.

3. The system of claim 1, wherein the biological tissue is skin.

4. The system of claim 3, wherein optical treatment of the skin involves laser tattoo removal.

5. The system of claim 3, wherein the skin is human skin.

7. The system of claim 5, wherein changing of the optical properties of biological tissues occurs in-vitro or ex-vivo.

8. The system of claim 5, wherein isolating the biological tissue is through surgical excision of tissue.

9. The system of claim 5, wherein the clarifying agent is delivered topically.

10. The system of claim 5, wherein the delivery of clarifying agent is through submersion of the said tissue in a clarifying agent.

6. A system for changing the optical properties of biological tissues comprising:

a) means of isolating the said biological tissue and removing the tissue permeability barrier; and

b) means of delivering of a clarifying agent to the biological tissue.
