Method of Marking Biological Tissues for Enhanced Destruction by Applied Radiant Energy
First Claim
1. A method for targeted destruction of biological tissues by application of radiant energy, comprising:
- a. a step of identifying targeted tissue;
b. a step of selecting a stain with an absorption spectrum corresponding to a wavelength of a given radiant energy source;
c. a step of applying the stain to a biological tissue substrate to be destroyed; and
d. a step of communicating radiant energy to the tumor with sufficient energy to destroy the targeted tissue through at least one process of destruction selected from the group of processes of destruction consisting of carbonization and vaporization, while simultaneously minimizing harm to tissue surrounding the targeted tissue.

Abstract
Methods for staining a selected tissue with a dye, stain or pigment that is attuned to absorb the energy from a radiant energy source are disclosed. The stain enhances absorption of incoming radiant energy, which results in increased destruction of stained tissues and decreased destruction of underlying tissues. This method provides clinicians with the ability to selectively mark a tissue for destruction, while leaving wanted tissues generally intact. Optionally, a radiant energy opaque substance that can be applied adjacent the stained treatment area to protect against incidental exposure to untargeted tissue. Also optionally, an oxidizing substance may be applied with the stain to further enhance the effect of this method. Wavelengths of radiant energy to which tissue is normally transparent may be utilized by applying appropriate stains to targeted tissue, thereby allowing targeted tissue to even be destroyed when it lies beneath untargeted tissue.
