摘要:
Interventional catheter-based systems and methods are described herein for use in generating an initial pathway through vascular occlusions. The catheter systems generally include two elements. A first element is a Blunt Dissection Catheter including a manually actuated assembly located at the distal tip of the Blunt Dissection Catheter that performs blunt dissection in the vascular occlusion to produce a dissection track, or small pathway through the occlusion. The second element is a Sheath Catheter that serves as a conduit within which the Blunt Dissection Catheter is freely advanced, retracted and rotated. The first and second elements are used in some combination to cross vascular occlusions in both the coronary and peripheral vasculature.

The present invention is directed to systems, apparatus, methods and procedures for the noninvasive treatment of tissue using microwave energy. In one embodiment of the invention a medical device and associated apparatus and procedures are used to treat dermatological conditions using microwave energy.
摘要:
An tissue interface module has an applicator chamber on a proximal side of the tissue interface module and a tissue acquisition chamber on a distal side of the tissue interface module. The applicator chamber may include: an opening adapted to receive the applicator; an attachment mechanism positioned in the applicator chamber and adapted to attach the tissue interface module to the applicator; a sealing member positioned at a proximal side of the applicator chamber; and a vacuum interface positioned at a proximal side of the applicator chamber and adapted to receive a vacuum inlet positioned on a distal end of the applicator. The invention also includes corresponding methods.

摘要:
A system applies, in a non-invasive manner, energy to a targeted tissue region employing a controlled source of energy, a multiple use applicator, and a single use, applicator-tissue interface carried by the applicator. The system can generate and apply energy in a controlled fashion to form a predefined pattern of lesions that provide therapeutic benefit, e.g., to moderate or interrupt function of the sweat glands in the underarm (axilla).
摘要:
Methods for integrating wide-gap semiconductors with synthetic diamond substrates are disclosed. Diamond substrates are created by depositing synthetic diamond onto a nucleating layer deposited or formed on a layered structure including at least one layer of gallium nitride, aluminum nitride, silicon carbide, or zinc oxide. The resulting structure is a low stress process compatible with wide-gap semiconductor films, and may be processed into optical or high-power electronic devices. The diamond substrates serve as heat sinks or mechanical substrates.
