METHODS AND DEVICES FOR THERMAL TISSUE VAPORIZATION AND COMPRESSION

摘要

A method of making an array of sharp tips comprising a biocompatible coating, wherein the biocompatible coating is thicker at the sharp end of the sharp tips than at the wide section of the sharp tips, the method comprising providing an array of sharp tips, and Coating the sharp ends of the sharp tips differently from the coating of the wide section of the tips. The method of treating the skin includes the step of creating a hollow in the skin by heating and mechanically compressing the epidermis while retaining the covering of the stratum corneum. The method of treating the tissue includes heating the tip to a temperature suitable to create puncture marks in the tissue, advancing the tip towards the tissue, and when the tip comes into contact with the tissue by detecting a change in mechanical resistance to advancing. And measuring a mechanical resistance to advance. Related apparatus and methods are also described.
