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.
Claims20
A patient tracking device for insertion into a body cavity comprising:
- a flexible conformable sensor housing comprising a sensor cavity therein, wherein the housing is configured to conform to the body cavity when inserted therein;
- and
- a sensor disposed within the housing;
- wherein the sensor housing is formed of flexible, resilient, compressible, expandable, and conformable material;
- wherein the sensor housing has a first form at rest, a second form as it is being inserted, and a third form within the body cavity, where the first, second and third forms are each different;
- wherein in the second form the sensor housing is compressed and in the third form the sensor housing automatically expands to conform and fix the patient tracking device in the body cavity.

A method of forming a patient tracking device comprising:
- forming a sensor cavity within a flexible conformable housing sized to fit within a body cavity;
- inserting an electromagnetic sensor within the sensor cavity;
- and
- retaining the electromagnetic sensor within the sensor cavity with a separate retainer;
- wherein the sensor housing is formed of flexible, resilient, compressible, expandable, and conformable material;
- wherein the sensor housing has a first form at rest, a second form as it is being inserted, and a third form within the body cavity, where the first, second and third forms are each different;
- wherein in the second form the sensor housing is compressed and in the third form the sensor housing automatically expands to conform and fix the patient tracking device in the body cavity.
4 more elements
A patient tracking device for positioning within a body cavity, comprising:
- a sensor housing defining a sensor cavity within the sensor housing;
- a tracking sensor sized and configured to be disposed within the sensor cavity in the sensor housing;
- and
- a separate retainer configured to retain the tracking sensor relative to the sensor cavity;
- wherein the sensor housing is formed of flexible, resilient, compressible, expandable, and conformable material;
- wherein the sensor housing has a first form at rest, a second form as it is being inserted, and a third form within the body cavity, where the first, second and third forms are each different;
- wherein in the second form the sensor housing is compressed and in the third form the sensor housing automatically expands to conform and fix the patient tracking device in the body cavity.
