Claim 9:
10. A method for thermal remodeling of a collagenous structure of an endopelvic fascia using high intensity directional ultrasound ablation comprising:
inserting an imaging probe to estimate a length of a urethra based on images from the imaging probe;
inserting a transurethral directional ultrasonic catheter to a desired depth into the urethra based upon the estimate, the transurethral directional ultrasonic catheter comprising:
a catheter;
a multi-directional-transducer array in communication with the catheter the multi-directional transducer array being directionally sectored into a plurality of sectors and comprising a plurality of angular zones, each angular zone defined by a sector of the plurality of sectors, wherein each sector of the plurality of sectors is independently operable and configured to emit energy in a direction around the catheter; and
a multi-chambered balloon positioned at a distal end of the catheter at a distal position with respect to the multi-directional-transducer array, the multi-chambered balloon being configured to anchor the transurethral directional ultrasonic catheter within the urethra, at least a portion of the multi-chambered balloon configured to be positioned in a cavity distal to a tissue such that the multi-directional-transducer array is positioned adjacent to the tissue, each chamber of the multi-chambered balloon being coaxially positioned along a longitudinal axis of the catheter and comprising the same shape;

selectively and independently inflating one or more chambers of the multi-chambered balloon within the urethra, positioning the multi-directional transducer at a treatment location along the length of the urethra relative to a bladder neck and fixing the transurethral directional ultrasonic catheter along the urethra;
rotating the transurethral directional ultrasonic catheter to orient the plurality of angular zones;
activating one or more of the plurality of zones, wherein activated zones are selected based the treatment location;
directing acoustic energy, from the multi-directional transducer, to selectively heat the treatment location from within the urethra; and
monitoring a temperature and an ultrasound dose of the treatment location.
