Abstract
The invention provides improved devices, methods, and systems for shrinking of collagenous tissues, particularly for treating urinary incontinence in a noninvasive manner by directing energy to a patient's own support tissues. This energy heats fascia and other collagenous support tissues, causing them to contract. Pre-cooling and/or pre-heating may induce a temperature difference between the target tissue and the intermediate tissue prior to initiating RF heating. This allows the dimensions of tissue reaching the treatment temperature to be controlled and/or minimized, the dimensions of protected intermediate tissue to be maximized, and the like.
