摘要： A catheter for measuring electrical activity and ablating tissue is provided. The catheter comprises an elongated generally-tubular catheter body. A non-retractable electrode assembly is mounted at the distal end of the catheter body. The electrode assembly comprises a generally tubular ablation electrode formed of a material having shape-memory having a generally straight exposed region and at least one irrigation port in the exposed region through which fluid can pass from the inside to the outside of the ablation electrode. The exposed region is generally transverse to the catheter body. The electrode assembly further comprises a tip at the distal end of the electrode assembly comprising a generally ball-shaped exposed region. First and second distal mapping electrodes are mounted distal to the exposed region of the ablation electrode. At least the first distal mapping electrode, and optionally the second distal mapping electrode, is incorporated into the generally ball-shaped exposed region of the tip. The catheter further comprises an infusion tube extending through the catheter body and having a distal end in fluid communication with the proximal end of the ablation electrode.

摘要： A catheter that is particularly useful for simultaneously mapping multiple points within the heart is provided. The catheter includes a mapping assembly including a plurality of flexible spines, each having a free distal end. The spines are supported by an improved support structure that permits the spines to be more precisely arranged relative to one another. The catheter comprises an elongated catheter body. A mapping assembly is provided at the distal end of the catheter body. The mapping assembly comprises a support structure having a generally cylindrical base mounted on the distal end of the catheter body, the base having proximal and distal ends. The support structure further comprises at least two pre-shaped flexible support arms. Each support arm has a proximal end attached to the distal end of the generally cylindrical base and a free distal end. At least two non-conductive coverings are provided, each in surrounding relation to a corresponding one of the at least two support arms. At least one electrode is mounted over each of the at least two non-conductive coverings.

摘要： A catheter adapted for mapping near a tubular region of a heart, has an elongated tubular catheter body having proximal and distal ends, an intermediate section distal of the catheter body, and a mapping assembly at the distal end of the intermediate section. The electrode-carrying mapping assembly has a generally circular main segment with a support member having shape-memory, and a generally linear proximal segment which has greater flexibility than either the intermediate section or the generally circular main segment. The generally circular main segment is adapted to releasably anchor itself in the tubular region and to map circumferentially around the tubular region and the generally linear segment is adapted to contact generally along its length heart wall tissue near an ostium of the tubular region. In another embodiment of the present invention, the mapping assembly extends from the distal end of the catheter body, where the generally linear proximal segment of the mapping assembly has greater flexibility than either the catheter body or the generally circular main segment.
