Abstract
A patient tracking device for insertion into a body cavity includes a flexible conformable sensor housing having a sensor cavity therein. The housing conforms to the body cavity when inserted therein. A sensor is disposed within the housing.
Claims23
A patient tracking device for insertion into a body cavity comprising:
- a flexible conformable sensor housing comprising a sensor cavity therein, wherein the sensor housing is configured to automatically conform to the body cavity when inserted therein;
- an electromagnetic tracking sensor disposed within the sensor cavity of the housing;
- and
- wherein the sensor housing is formed of a resilient material;
- wherein the sensor housing is configured to be compressed into a first configuration before placement into the body cavity and configured to expand in a second configuration after positioning in the body cavity.

A method of forming a patient tracking device comprising:
- forming a sensor cavity within a flexible conformable sensor housing sized to fit within a body cavity;
- inserting an electromagnetic tracking sensor within the sensor cavity;
- and
- retaining the electromagnetic tracking sensor within the sensor cavity;
- wherein the sensor housing is formed of a resilient material;
- wherein the sensor housing is configured to be compressed into a first configuration before placement into the body cavity and configured to expand in a second configuration after positioning in the body cavity.
3 more elements
A patient tracking device for insertion into a body cavity of a patient comprising:
- a sensor housing defining a sensor cavity within the sensor housing, the sensor housing being formed of a resilient material that is flexible, resilient and conformable;
- and
- an electromagnetic tracking sensor disposed within the sensor cavity of the sensor housing;
- wherein the sensor housing is configured to automatically transform its shape to conform to the body cavity to substantially fix the sensor housing and electromagnetic tracking sensor in relation to the patient in a non-invasive manner;
- wherein the sensor housing is configured to be compressed into a first configuration before placement into the body cavity and configured to expand in a second configuration after positioning in the body cavity.
