Abstract
The invention provides an asymmetrically flexible cardiac mapping catheter that includes a deformation mechanism by which a user may deform a distal portion of the catheter giving the user the ability to reach, and map electrical activity of, substantially any surface within the heart.
Claims20
A cardiac mapping catheter comprising:
- an elongated catheter body having a proximal portion and a distal portion;
- a head comprising an electrode array connected to the distal portion of the catheter body through a neck portion;
- a deformation mechanism operable to deform the distal portion to position an electrode of the electrode array at substantially any location on a cardiac surface;
- and at least one conductive lead extending from the electrode to the proximal portion of the catheter body.

A method of for mapping arrythmia or fibrillation in a heart, the method comprising:
- navigating a distal portion of a catheter into a chamber of heart, wherein the distal portion of the catheter carries a head comprising a deformable leaf of material with at least one electrode on a first a surface of the deformable leaf;
- operating a deformation mechanism of the catheter by manipulating an actuator connected to a proximal portion of the catheter to thereby deform the deformable leaf so that the first surface exhibits a first curve in a first direction;
- controlling the actuator to deform the leaf to cause the first surface to exhibit a second curve in a second direction opposed to the first direction;
- and measuring electrical activity of tissue of the heart while the first surface has the first curve and while the first surface has the second curve.
