US Patent:

7081096, Jul 25, 2006

Filed:

Jan 24, 2003

Appl. No.:

10/351162

Inventors:

Mark Brister - Forestville CA, US
Dave Thompson - Andover MN, US
James Carney - Eden Prairie MN, US

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61B 5/00

US Classification:

600549

Abstract:

The temperature mapping balloon of the present invention provides a device for locating inflammation and increased metabolic activity associated with conditions such as vulnerable plaque, by mapping temperature of a body lumen, such as an artery or blood vessel. The temperature mapping balloon comprises a balloon with a thermal mapping coating disposed on the inside or outside of the balloon. The thermal mapping coating can be a thermochromic coating that changes color in response to temperature or a sensor coating comprising a plurality of temperature sensors.

International Classification:

A61B 5/00

US Classification:

600549

Abstract:

A method and apparatus for determining vulnerable plaque in a cardiovascular lumen is disclosed. In one embodiment, a guide member comprising a temperature sensor and a distance sensor are inserted into the cardiovascular lumen. The temperature of the cardiovascular wall is measured with the temperature sensor, and the distance from the temperature sensor to the cardiovascular wall is determined. The cardiovascular wall temperature is adjusted based on the distance determination, and the vulnerable plaque is determined based on the adjusted wall temperature measurement.

International Classification:

A61B 5/00
A61B 5/05

US Classification:

600347, 600365, 600345

Abstract:

Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.
