20110054315MICROMANIPULATOR CONTROL ARM FOR THERAPEUTIC AND IMAGING ULTRASOUND TRANSDUCERS - A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can image a target tissue volume and apply ultrasound energy to the target tissue volume. In some embodiments, the medical imaging and therapy device is configured controllably apply ultrasound energy into the prostate by maintaining a cavitational bubble cloud generated by an ultrasound therapy system within an image of the prostate generated by an imaging system. The medical imaging and therapy device can be used in therapeutic applications such as Histotripsy, Lithotripsy, and HIFU, for example. Methods associated with use of the medical imaging and therapy device are also covered.03-03-2011
20110054363DEVICES AND METHODS FOR USING CONTROLLED BUBBLE CLOUD CAVITATION IN FRACTIONATING URINARY STONES - A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can deliver Lithotripsy therapy to a patient, so as to fractionate urinary stones. Another feature of the device is that it can deliver Histotripsy therapy to a patient, so as to erode urinary stones. In some embodiments, the medical imaging and therapy device is configured to target and track urinary stones in the patient during therapy. Methods associated with use of the medical imaging and therapy device are also covered.03-03-2011
20110067624GEL PHANTOMS FOR TESTING CAVITATIONAL ULTRASOUND (HISTOTRIPSY) TRANSDUCERS - A cavitational ultrasound (e.g., Histotripsy) gel phantom and cavitational ultrasound testing system are provided that may include any of a number of features. One feature of the phantom and system is that it can allow for instant visual feedback on the efficacy and dosage of a Histotripsy transducer. The changes in the gel phantom can be visualized with the naked eye without having to wait for histology. The changes in the gel phantom can also be visualized with a camera, with ultrasound imaging, or with microscopy. In various embodiments, the phantom includes indicators such as carbon particles, dye-encapsulated beads, and red blood cells. Methods associated with use of the cavitational ultrasound gel phantom and testing system are also covered.03-24-2011
20120010541Pulsed Cavitational Ultrasound Therapy - Therapy methods using pulsed cavitational ultrasound therapy can include the subprocesses of initiation, maintenance, therapy, and feedback of the histotripsy process, which involves the creation and maintenance of ensembles of microbubbles and the use of feedback in order to optimize the process based on observed spatial-temporal bubble cloud dynamics. The methods provide for the subdivision or erosion of tissue, liquification of tissue, and/or the enhanced delivery of therapeutic agents. Various feedback mechanisms allow variation of ultrasound parameters and provide control over the pulsed cavitational process, permitting the process to be tuned for a number of applications. Such applications can include specific tissue erosion, bulk tissue homogenization, and delivery of therapeutic agents across barriers.01-12-2012
