Abstract
An improved catheter is provided that is particularly useful for mapping the pulmonary vein and other tubular regions of or near the heart. The catheter comprises an elongated catheter body having a proximal end, a distal end and at least one lumen extending longitudinally therethrough. A mapping assembly is mounted at the distal end of the catheter body and comprises a stem and at least two spines. The spines are moveable between a collapsed position, where each spine has a distal end attached to the stem, and a free proximal end positioned generally against the stem, and an expanded position, where the free proximal end of each spine extends outwardly from the stem. Each spine carries at least one electrode.

A catheter comprising:
- an elongated catheter body having a proximal end, a distal end and at least one lumen extending longitudinally therethrough;
- a mapping assembly mounted at the distal end of the catheter body and comprising a stem and at least two spines moveable between a collapsed position, where each spine has a distal end attached to the stem and a free proximal end positioned generally against the stem, and an expanded position, where the free proximal end of each spine extends outwardly from the stem, and wherein each spine carries at least one electrode, and at least one location sensor.
A catheter comprising:
- an elongated catheter body having proximal and distal ends and at least one lumen extending longitudinally therethrough;
- a mapping assembly mounted at the distal end of the catheter body comprising a stem and at least two spines moveable between a collapsed position, in which each spine has a distal end attached to the stem and a free proximal end positioned generally against the stem, and an expanded position, in which the free proximal end of each spine extends outwardly from the stem, wherein each spine carries at least one electrode;
- and
- a spine mounting assembly for mounting the spines to the stem, the spine mounting assembly comprising:
