Soft linear mapping catheter with stabilizing tip
First Claim
1. A mapping catheter adapted for mapping near a tubular region of a heart, comprising:
- an elongated tubular catheter body having an outer wall, proximal and distal ends, and at least one lumen extending therethrough;
an intermediate section having proximal and distal ends, the intermediate section being distal of the catheter body; and
a mapping assembly at the distal end of the intermediate section, the mapping assembly having;
a generally circular main segment with a support member having shape-memory disposed within at least the main segment of the mapping assembly,a generally linear segment proximal the generally circular main segment, the generally linear segment having greater flexibility than either of the intermediate section and the generally circular main segment, anda plurality of ring electrodes on the generally linear segment,wherein the generally circular main segment is adapted to releasably anchor itself in the tubular region and wherein the generally linear segment is adapted to contact generally along its length heart wall tissue near an ostium of the tubular region.

Abstract
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.
