## Abstract

Systems and methods for transvaginal high intensity concentrated ultrasound. Urinary incontinence is treated through application of high intensity ultrasound to tissue structures to affect a change in the tissue.

## Claims

### Claim 1

A system for transvaginally treating stress urinary incontinence comprising:
transvaginal applicator having:
a first curved transducer array comprising a first plurality of transducers aligned along a first array longitudinal axis, the first curved transducer array further having a first therapeutic zone;
a second curved transducer array comprising a second plurality of transducers aligned along a second array longitudinal axis, the second curved transducer array further having a second therapeutic zone, the first therapeutic zone and the second therapeutic zone are not overlapping, with a dead zone in between the first therapeutic zone and the second therapeutic zone;
an imaging transducer array positioned between the first curved transducer array and the second curved transducer array, the imaging transducer array having an imaging array longitudinal axis and movable relative to the first curved transducer array and the second curved transducer array, the imaging transducer array pivotably positioned about the imaging array longitudinal axis relative to the first curved transducer and the second curved transducer, wherein the imaging transducer array is positioned to pivotally scan the first therapeutic zone, then the dead zone, and then the second therapeutic zone;
an acoustic coupling balloon; and
a positioning balloon.

### Claim 2 (depends on 1)

The system of claim 1, further comprising orientation markers.

### Claim 3 (depends on 1)

The system of claim 1, wherein the first curved transducer array comprises a first angular sectioned transducer array and the second curved transducer array comprises a second angularly sectioned transducer array.

### Claim 4 (depends on 1)

The system of claim 1, wherein the at least one transducer array comprises a first transducer array and a second transducer array that are positioned at about 50 degrees to about 70 degrees with respect to each other.

### Claim 5 (depends on 1)

The system of claim 1, further comprising an acoustic coupling fluid circulation subsystem coupled to the acoustic coupling balloon.

### Claim 6 (depends on 1)

The system of claim 1, further comprising a multi-channel generator coupled to the at least one transducer array.

### Claim 7 (depends on 1)

The system of claim 1, further comprising an ultrasound imaging system coupled to the imaging transducer.

### Claim 8 (depends on 1)

The system of claim 1, wherein the applicator is selected from the group consisting of ablator, catheter, and interstitial needle.

### Claim 9 (depends on 4)

The system of claim 4, wherein the first therapeutic zone and the second therapeutic zone are each 0.5 cm to 2.0 cm beyond the transvaginal applicator.

### Claim 10 (depends on 1)

The system of claim 1, wherein the imaging transducer array longitudinal axis is parallel with the first array longitudinal axis and the second array longitudinal axis.
