Systems And Methods For Sensing External Magnetic Fields In Implantable Medical Devices

View page
US Patent:
20080071168, Mar 20, 2008
Filed:
Jul 26, 2006
Appl. No.:
11/460081
Inventors:
Karl Gauglitz - Snohomish WA, US
Thomas M. Bocek - Seattle WA, US
Mark Rutzer - Seattle WA, US
Lorin W. Matthews - Brier WA, US
William E. Reagor - Bellevue WA, US
Blair Erbstoeszer - Kirkland WA, US
International Classification:
A61B 5/05
A61B 6/00
A61M 25/00
G01V 3/00
US Classification:
600423, 600435, 324322
Abstract:
Systems and methods for sensing external magnetic fields in implantable medical devices are provided. One aspect of this disclosure relates to an apparatus for sensing magnetic fields. An apparatus embodiment includes a sensing circuit with at least one inductor having a magnetic core that saturates in the presence of a magnetic field having a prescribed flux density. The apparatus embodiment also includes an impedance measuring circuit connected to the sensing circuit. The impedance measuring circuit is adapted to measure impedance of the sensing circuit and to provide a signal when the impedance changes by a prescribed amount. According to an embodiment, the sensing circuit includes a resistor-inductor-capacitor (RLC) circuit. The impedance measuring circuit includes a transthoracic impedance measurement module (TIMM), according to an embodiment. Other aspects and embodiments are provided herein.
