METHODS AND DEVICES FOR TISSUE ABLATION

摘要

A device for vaporizing a hole in tissue, including a vaporizing element, a heating element, configured to heat the vaporizing element, and a mechanism configured to advance the vaporizing element into a specific depth in the tissue and retract the vaporizing element from the tissue within a period of time long enough for the vaporizing element to vaporize the tissue and short enough to limit diffusion of heat beyond a predetermined collateral damage distance from the hole. Related apparatus and methods are also described.

1. A device for evaporating tissue, comprising:
a vaporizing element; a heating element, configured to heat the vaporizing element to a high temperature; and a mechanism configured to advance the vaporizing element into a specific depth in the tissue which is smaller or equal to a papillary dermis depth within live skin and retract the vaporizing element from the tissue producing a hole in the tissue, wherein the high temperature is above 400 degrees Celsius; the vaporizing element comprises a hollow element with a closed tip; and an external surface of the vaporizing element is formed of a material biocompatible at the high temperature.
