Abstract

Abstract A method is disclosed for forming and contracting scar collagen below a tissue surface in a selected tissue site. An electromagnetic energy apparatus is provided and includes an electromagnetic energy source and a delivery device. The delivery device is positioned on the tissue surface. Electromagnetic energy is produced from the electromagnetic energy source and delivered through the tissue surface to the selected tissue site for a sufficient time to induce scar collagen formation in the selected tissue site. No more than a second degree burn is formed on the tissue surface. The scar collagen is then contracted. This method is particularly useful in tissue sites that are devoid or deficient in collagen.

Claims Analysis

Total Claims: 26
Claim 1
Independent Claim 107 words
A method for inducing the formation of scar collagen in a selected collagen containing tissue site beneath an epidermis skin surface, comprising: providing an energy source; producing energy from the energy source; creating a reverse thermal gradient through the skin epidermis surface where a temperature of the skin epidermis surface is lower than the selected collagen containing tissue site; and delivering energy from the energy source through the skin epidermis surface to the selected collagen containing tissue site for a sufficient time to induce collagen formation in the selected collagen containing tissue site, minimizing cellular necrosis of the skin epidermis surface and tightening the skin epidermis surface.
Claim 2
Independent Claim 107 words
A method for inducing the formation of scar collagen in a selected collagen containing tissue site beneath an epidermis skin surface, comprising: providing an energy source; producing energy from the energy source; creating a reverse thermal gradient through the skin epidermis surface where a temperature of the skin epidermis surface is lower than the selected collagen containing tissue site; and delivering energy from the energy source through the skin epidermis surface to the selected collagen containing tissue site for a sufficient time to induce collagen formation in the selected collagen containing tissue site, minimizing cellular necrosis of the skin epidermis surface and tightening the skin epidermis surface.
Claim 3
Dependent Claim 19 words

Claim 4
Dependent Claim 19 words
The method of claim 1 , wherein the energy is percutaneously delivered to the selected collagen containing tissue site.
Claim 5
Dependent Claim 18 words
The method of claim 1 , wherein the energy is transmucosally delivered to the selected collagen containing site.
Claim 6
Dependent Claim 19 words
