Abstract
Provided are a variety of systems, techniques and machine readable programs for using plasmas to treat different skin conditions as well as other conditions, such as tumors, bacterial infections and the like. Flexible treatment electrodes are provided to conform to anatomical surfaces that can be inflatable in some implementations to conform the surface of the flexible treatment electrodes to the anatomy being treated.
Claims25
A system for applying a plasma discharge, comprising:
- a) an electrode adapted to be placed proximate an anatomical region of interest, the electrode being defined at least in part by a flexible electrode surface that is configured to conform to the curvature of the anatomical region to be treated with a plasma to create a substantially uniform gap between the flexible electrode surface and the anatomical region of interest to be treated to facilitate formation of a substantially uniform plasma across the anatomical region to be treated;
- wherein the electrode includes a motor for varying the electrode position to prevent formation of microdischarges in the plasma induced by the system during system operation;
- and
- b) a power supply in electrical communication with the electrode, the power supply being configured to apply a pulsed voltage waveform having pulses with durations between about one picosecond and about 100 nanoseconds to help prevent formation of microdischarges between the electrode and the anatomical region of interest.

A system for applying a plasma discharge, comprising:
- a) an electrode adapted to be placed proximate an anatomical region of interest, wherein the electrode includes a motor for varying the electrode position to facilitate uniformity in exposure to the anatomical region of interest exposed to the plasma discharge induced by the system during system operation;
- wherein the electrode is defined at least in part by a flexible electrode surface that is configured to conform to the curvature of the anatomical region of interest to be treated with the plasma discharge to create a substantially uniform gap between the flexible electrode surface and the anatomical region of interest to be treated to facilitate formation of a substantially uniform plasma across the anatomical region to be treated;
- and
- b) a power supply in electrical communication with the electrode, the power supply being configured to apply a pulsed voltage waveform having pulses with durations between about 0.010 seconds and about 0.0000010 seconds to help prevent formation of microdischarges between the electrode and the anatomical region of interest in cooperation with movement of the motor.
