Claim 16:
17. A method for treating a targeted region within a tissue with ultrasound treatment comprising:
forming, by an apparatus for ultrasound treatment, a multi-angular ablation pattern comprising a plurality of treatment zones delivering acoustic power to selectively ablate the targeted region, the apparatus 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 in the plurality of sectors is independently operably and emits 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 configured to anchor the apparatus with respect to the targeted region, at least a portion of the multi-chambered balloon positionable in a cavity distal to the targeted region such that the multi-directional transducer array is positioned adjacent to the targeted region, each chamber of the multi-chambered balloon coaxially positioned along a longitudinal axis of the catheter, comprising the same shape, and independently inflatable within the cavity to longitudinally position the multi-directional transducer array with respect to the targeted region;

controlling a directionality and a shape of the multi-angular ablation pattern by activating at least a portion of the plurality of sectors, the activated sectors emitting energy in multiple angular directions and defining the plurality of treatment zones corresponding to the targeted region; and
controlling at least one of an ablation intensity, of the multi-angular ablation pattern, or a penetration depth, of the multi-angular ablation pattern, by controlling a level of acoustic power delivered to the treatment region by delivering, by a first set of the activated sectors, a first acoustic power level to the treatment region and by delivering, by a second set of the activated sensors, a second acoustic power level to the treatment region.
