Filed:

Oct 21, 2009

Appl. No.:

12/603349

Inventors:

Chun Yiu CHU - Fremont CA, US

Assignee:

MICROCUBE, LLC - Fremont CA

International Classification:

A61B 18/18

US Classification:

606 33

Abstract:

Devices and methods are disclosed for treating tissue with microwave energy. Such devices and methods are able to treat cavities or surface tissue by creating one or more area or volumetric lesions. Also disclosed are flexible, low-profile devices that can be inserted non-invasively or minimally invasively near or into the target tissue as well as microwave antennas designed to generate ablation profiles that can ablate a large area or a large volume of target tissue in a single ablation. The devices include antennas wherein the field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas use unique properties of microwaves such as interaction of a microwave field with a metallic object and the use of additional shaping elements to shape the microwave field.

International Classification:

A61B 18/18

US Classification:

606 33

Abstract:

The invention comprises novel microwave antennas wherein the microwave field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas disclosed herein incorporate one or more additional elements called shaping elements that use unique properties of microwaves such as interaction of a microwave field with one or more conductive or non-conductive elements to shape or redistribute the microwave field. Such shaping elements may be used to reduce the undesired backward coupling of the emitted microwave field to the transmission line. Such shaping elements may be used to increase the power efficiency of the antenna. The invention also discloses devices and methods for treating tissue with microwave energy emitted from the antennas for use in applications such as destroying a soil tissue by microwave ablation.

Jessica Liu STROHMANN - Cupertino CA, US

International Classification:

G06K 9/00
G06K 9/03
G01L 1/18
G01L 25/00

Abstract:

A method may involve controlling, via a control system, the apparatus to provide a first prompt to place a digit on an outer surface of the apparatus in a fingerprint sensor system area. The method may involve determining, via the control system, a digit force or a digit pressure of the digit on the outer surface of the apparatus. The method may involve controlling, via the control system, the apparatus to provide a second prompt corresponding to the digit force or the digit pressure.
