System and method using chemicals and ultrasound or ultrasound alone to replace more conventional surgery
First Claim
1. A method for rendering a gallbladder dysfunctional without surgical removal comprising the steps of infusing the gallbladder with methyl-tert-butyl ether (MTBE), then, while the gallbladder is so infused, irradiating the gallbladder with an ultrasound beam in such an ultrasound delivery format as not to elevate the average temperature of the gallbladder more than five degrees Centigrade over the period of treatment, and then removing the MTBE from the gallbladder, and then repeating these steps a sufficient number of times to render the gallbladder dysfunctional.

4. The method of 1 wherein the ultrasound delivery format includes a frequency in the range of 200-250 KHz, a spatial peak-temporal peak (SPTP) intensity of 12-24 W/cm2 over the cross sectional area of the gallbladder, a duty cycle in the range of 10%-20%, and an ultrasound exposure time of 30-90 minutes.
