Abstract
An electrophysiology catheter, e.g., a coronary sinus catheter, for insertion into a cardiac vessel, such as the coronary sinus, includes a handle and a catheter shaft coupled at one end to the handle. The catheter shaft has a distal end and an anchor is associated with the catheter shaft and is movable between a deployed position and a collapsed position. In the deployed position, the anchor extends radially outward from an outer surface of the catheter shaft for contacting a wall and temporarily anchoring the catheter shaft within the coronary sinus. The catheter also includes an actuator for causing deployment and collapsing of the anchor upon manipulation of the actuator.
Claims14
An electrophysiology catheter for insertion into a cardiac vessel comprising:
- a handle;
- a catheter shaft coupled at one end to the handle, the catheter shaft having a distal end,
- an anchor associated with the catheter shaft and movable between a deployed position and a collapsed position, wherein in the deployed position, the anchor extends radially outward from an outer surface of the catheter shaft for contacting a wall of the cardiac vessel and temporarily anchoring the electrophysiology catheter shaft within the cardiac vessel, wherein the anchor functions as a recording electrode;
- a plurality of electrodes that are disposed along the catheter shaft, wherein the anchor is disposed between a first set of electrodes and a second set of electrodes;
- and
- an actuator for causing deployment and collapsing of the anchor within the cardiac vessel.
