Abstract: The present invention relates to systems and devices for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In particular, the present invention relates to systems and devices for the delivery of energy with heat transfer ability. In some embodiments, the systems and devices also have variable characteristic impedance as a result of the use of heat transfer materials. In certain embodiments, methods are provided for treating a tissue region (e.g., a tumor) through application of energy with the systems and devices of the present invention.

Abstract: A method of heating a tissue using pulsed focused ultrasonic waves, and an apparatus for carrying out the method. The method comprises depositing an amount of ultrasound energy sufficient to heat the selected site without adversely damaging other parts of the tissue. The apparatus comprises an ultrasonic source for producing pulsed ultrasonic waves, a lens for focusing the ultrasonic waves, and a controller for controlling wave frequency and transmission parameters of the ultrasonic waves. The method and apparatus can be used to treat spine or other joint disorders associated with lax ligamentous tissues, i.e., soft tissue disruption.

Abstract: Finely divided pellets or granules are formed from a molten explosive comition by a combination of spray chilling and prilling techniques, which comprises atomizing the molten explosive composition in a high velocity stream of an inert gas such as air and allowing the atomized droplets to fall through a tower countercurrent to a stream of an inert gas to cool the droplets to form solid pellets. The process is advantageously employed for producing meltable explosive materials, e.g., Composition B, in the form of free flowing spherical pellets of high density and uniform composition.
