First Claim
Patent Images
1. A medical device, comprising:
- an applicator body, comprising a terminal for receiving radio-frequency (RF) electrical power; and
an array of protrusions disposed on a front side of the applicator body and configured to maintain a space between at least a majority of the protrusions and a skin surface of a patient when the applicator body is brought into proximity with the skin surface so as to cause electrical discharges to be generated, in response to the RF electrical power, between the majority of the protrusions and respective points on the skin surface via a fluid medium in the space.

Abstract
A method for medical treatment includes bringing an applicator, having an array of protrusions disposed thereon, into proximity with a skin surface of a patient so as to maintain a space between a plurality of the protrusions and the skin surface. Radio-frequency (RF) electrical power is applied to the applicator so as to cause electrical discharges to be generated, in response to the RF electrical power, between the plurality of the protrusions and respective points on the skin surface via a fluid medium in the space.
