US Classification:
600427, 600439, 600459, 601 2
Abstract:
Noninvasive pain treatment of skeletal cancer metastases in cancer patients utilizing planar or focused ultrasound. The ultrasound energy preferably targets at the Periosteum or immediate soft-bone-tissue interface, where local sensory pain receptors are directly affected by the growing tumor, to generate heat to destroy local sensory pain receptors so as to interrupt or block the pain feedback pathway to the central nervous system.
Thermally Enhanced Piezoelectric Composite System And Method

International Classification:
H01L 41/04 G01N 29/00
US Classification:
310334, 310322, 29 2535
Abstract:
A system and method for removing unwanted heat generated by a piezoelectric element of an ultrasound transducer. Some implementations have high thermal conductivity (HTC) material placed adjacent to the piezoelectric element. The HTC material can be thermally coupled to one or more heat sinks. Use of HTC material in conjunction with these piezoelectric element surfaces is managed to avoid degradation of propagating acoustic energy. Use of the HTC material in conjunction with heat sinks allows for creation of thermal paths away from the piezoelectric element. Active cooling of the heat sinks with water or air can further draw heat from the piezoelectric element. Further implementations form a composite matrix of thermally conductive material or interleave thermally conductive layers with piezoelectric material.

Catheter Based Arrays For Intracardiac Ultrasound Imaging
John Swanson - Portland OR, US Richard Sass - Portland OR, US Jerome Boogaard - Forest Grove OR, US David Sahn - Oswego OR, US Perry Kaminski - Stehekin WA, US
International Classification:
A61B008/02
US Classification:
600/450000
Abstract:
An ultrasound probe assembly adapted for bio-imaging. The assembly comprises a catheter, an electrical assembly, including a set of linear conductors, at least partially housed within said catheter. An ultrasound transceiving unit is electrically connected to said electrical assembly and can be placed in both an undeployed state in which the transceiving unit is oriented coincidentally to said catheter and a deployed state in which it is directed to provide imaging signals over a volume of interest.
Treatment Of Cardiac Arrhythmia Utilizing Ultrasound
Eugene Larson - Lummi Island WA, US Perry Kaminski - Stehekin WA, US
International Classification:
A61F002/00
US Classification:
607101000
Abstract:
A noninvasive or minimally invasive treatment of cardiac arrhythmia such as supraventricular and ventricular arrhythmias, specifically atrial fibrillation and ventricular tachycardia, by treating the tissue with heat produced by ultrasound, (including High Intensity Focused Ultrasound or HIFU) intended to have a biological and/or therapeutic effect, so as to interrupt or remodel the electrical substrate in the tissue area that supports arrhythmia.
