Telescoping Catheter With Electromagnetic Coils for Imaging and Navigation During Cardiac Procedures
First Claim
1. An image guided navigation system for mapping at least one of the shape, size and location of a structure within a heart of a patient, the system comprising:
- a catheter system comprising a first catheter comprising a longitudinally extending lumen, a second catheter comprising a longitudinally extending lumen and positioned at least partially within and moveable relative to the lumen of the first catheter, an elongated member positioned at least partially within and moveable relative to a lumen of the second catheter, a first detectable marker located at a generally distal end of the first catheter, a second detectable marker located at a generally distal end of the second catheter, and a third detectable marker located at a generally distal end of the elongated member;
wherein at least one of the three detectable markers is axially moveable relative at least one of the other detectable markers.

Abstract
An image guided navigation system for mapping at least one of the shape, size and location of a structure within a heart of a patient, including a catheter system having a first catheter with a longitudinally extending lumen, a second catheter having a longitudinally extending lumen and positioned at least partially within and moveable relative to the lumen of the first catheter, an elongated member positioned at least partially within and moveable relative to a lumen of the second catheter, a first detectable marker located at a generally distal end of the first catheter, a second detectable marker located at a generally distal end of the second catheter, and a third detectable marker located at a generally distal end of the elongated member, wherein at least one of the three detectable markers is axially moveable relative to at least one of the other detectable markers.

11. A method of determining and mapping at least one of a shape and a location of a predetermined anatomical structure, the method comprising the steps of:
-
providing a telescoping catheter system comprising at least two coaxially positioned catheters and an elongated member coaxially positioned within the two coaxially positioned catheters, wherein a distal end of each of the catheters and the elongated member comprises a detectable marker; inserting the catheter system into a patient to the location of the predetermined anatomical structure; axially moving at least one of the detectable markers relative to at least one other of the detectable markers; and detecting the relative movement of the markers with at least one sensor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
