Estimating the term…
A method is disclosed for limiting temperature increase of a treatment area during photodynamic therapy (PDT), whereby temperature sensitive materials in the form of a skin patch or compound are applied over the treatment area. The temperature sensitive materials are optically changing from substantially transmissive to at least one of substantially scattering, absorbing or reflecting at wavelengths used for the PDT, the change occurring upon surpassing a predetermined temperature. In preferred embodiments, the optical changes are reversible as the temperature of the temperature sensitive compounds decrease below a predetermined temperature.
A method to limit temperature increases in a treatment area during an optically based therapeutic process that results in the heating of the treatment area, the method comprising:
A patch for use during an optically based therapeutic procedure, the patch comprising:
A composition of matter for use during photodynamic therapy, the composition of matter comprising:
A patch for application to a tissue during an optically based therapeutic process that results in the heating of the tissue, the patch comprising:
