METHODS AND DEVICES FOR APPLYING ENERGY TO TISSUE
First Claim
Patent Images
1. A medical device for treating a portion of skin, comprising:
- a housing including a outer housing surface, an inner housing surface at least partially defining a main chamber for treating a volume of skin, and a sealing surface, wherein placing the sealing surface against a portion of skin forms a portion of the main chamber, the housing surface including at least one channel in fluid communication with a pressure source; and
a needle electrode coupled to the inner housing surface, wherein the electrode is recessed within the main chamber and configured to apply energy when negative pressure is applied through the at least one channel and when the needle pierces the portion of skin.
