Sensor assembly for use in medical position and orientation tracking

Abstract

A sensor assembly is provided for use in tracking a medical device. The sensor assembly comprises a magnetoresistance sensor capable of providing position and orientation information. In certain implementations, the magnetoresistance position and orientation sensor is originally configured for connection to a substrate using one type of interconnect approach but is modified to be connected using a different interconnect approach.

Description

BACKGROUND[0001]The subject matter disclosed herein relates generally to sensors that may be used to provide position and orientation information for an instrument, implant or device used in a medical context, such as in a surgical or interventional context. In particular, the subject matter relates to a sensor assembly sized to fit within a medical instrument, implant or device.[0002]In various medical contexts it may be desirable to acquire position and / or orientation information for a medical instrument, implant or device that is navigated or positioned (externally or internally) relative to a patient. For example, in surgical and / or interventional contexts, it may be useful to acquire position and / or orientation information for a medical device, or portion of a medical device, even when the device or relevant portion is otherwise out of view, such as within a patient's body. Likewise, in certain procedures where an imaging technique is used to observe all or part of the position...
