Abstract

A navigation element for delivery of a therapy delivery system and method of enabling navigation of a therapy delivery system. The navigation element for a therapy delivery system comprises a flexible elongate tubular sheath having a lumen extending longitudinally therethrough, the lumen of the tubular body being sized to fit over a catheter; and an electromagnetic receiver assembly within the tubular body, the receiver assembly comprising a receiver coil and a conductor coupled to the receiver coil, the conductor coupled to the receiver coil and extending towards a proximal end of the tubular sheath.

Claims

1. A navigation element for a therapy delivery system comprising:

a flexible elongate tubular sheath having a lumen extending longitudinally therethrough, the lumen of the tubular body being sized to fit over a catheter; and

an electromagnetic receiver assembly within the tubular body, the receiver assembly comprising a receiver coil and a conductor coupled to the receiver coil, the conductor coupled to the receiver coil and extending towards a proximal end of the tubular sheath.

2. The navigation element of claim 1, wherein the catheter is an electrophysiology catheter such that the lumen of the tubular body is sized to fit over an electrophysiology catheter.

3. The navigation element of claim 1, wherein the navigation element further comprises a locking mechanism for locking a medical device within the lumen of the navigation element.

4. The navigation element of claim 3, wherein the locking mechanism is located at a proximal end of the tubular body and includes a lumen which is aligned with the lumen of the tubular body.

5. The navigation element of claim 1, wherein the receiver coil comprises a coiled wire.

6. The navigation element of claim 5, wherein the coiled wire forms a coil around the lumen of the tubular body.

7. The navigation element of claim 1, further comprising multiple electromagnetic receiver assemblies within the tubular body.

8. The navigation element of claim 7, wherein the receiver assembly comprises three receiver coils.

9. The navigation element of claim 1 further comprising one or more sensors.

10. A navigation element for a therapy delivery system made comprising:

an inner tubular body having an interior surface and an exterior surface and having a lumen extending longitudinally therethrough, the lumen being sized to fit over an elongate medical device;

an electromagnetic receiver assembly comprising a receiver coil wound around a portion of the exterior surface of the inner tubular body; and

an outer tubular body having a an interior surface and an exterior surface and having a lumen extending longitudinally therethrough, the interior surface of the outer tubular body being adjoined to the exterior surface of the inner tubular body and the electromagnetic receiver assembly.

11. The navigation element of claim 10, wherein the medical device is an electrophysiology catheter.

12. The navigation element of claim 10, further comprising a locking mechanism for locking the medical device within the lumen of the navigation element.

13. The navigation element of claim 12, wherein the locking mechanism is located at a proximal ends of the inner and outer elongate tubular bodies and wherein the locking mechanism includes a lumen which is aligned with the lumen of the inner first elongate tubular body.

14. The navigation element of claim 10, further comprising multiple electromagnetic receiver assemblies within the tubular body.

15. The navigation element of claim 14, wherein the navigation element comprises nine receiver assemblies.

20. The method of claim 15, wherein the medical device comprises an electrophysiology catheter.

16. A method of enabling navigation of a catheter comprising:

providing a navigation element, the navigation element including a flexible elongate tubular sheath having a lumen extending longitudinally therethrough and having an electromagnetic receiver assembly within the tubular body, the electromagnetic receiver assembly including a receiver coil positioned proximate to a distal end of the navigation element; and

inserting the catheter into the lumen of the navigation element such that the receiver coil is positioned in proximity to a distal end of the catheter.

17. The method of claim 16, wherein at least a portion of the catheter has a solid cross section.

18. The method of claim 16, wherein the navigation element further comprises a locking mechanism.

19. The method of claim 18, further comprising locking the medical device within the navigation element.
