Abstract:
1. A method for controlled mechanical sub-division of soft tissue comprising: de-initiating a non-treatment portion of the soft tissue to increase a cavitation threshold from a first threshold to a second threshold in said non-treatment portion of the soft tissue, wherein said de-initiating said non-treatment portion of the soft tissue comprises de-initiating said non-treatment portion of the soft tissue using a deleting pulse sequence at a pulse intensity less than said first threshold; using a transducer outputting an initiation pulse sequence at a treatment portion of the soft tissue, wherein said de-initiating a non-treatment portion of the soft tissue and said outputting an initiation pulse sequence are performed simultaneously; detecting initiation of a bubble cloud in said treatment portion of the soft tissue in response to said initiation pulse sequence; outputting a bubble cloud maintenance and sustaining pulse sequence at said treatment portion; and outputting a therapy pulse sequence which generates and interacts with said bubble cloud to at least partially fractionate the soft tissue in said treatment portion.
