Catheter with distal section having side-by-side loops

摘要

The catheter allows mapping and/or ablation of the area around two or more PV ostia at the same time, with a single placement of a distal section of the catheter having a 2D configuration resembling an infinity or lazy 8 symbol. The catheter has an elongated catheter body, a distal section having at least a flexible elongated member with shape memory, the member being configured to assume a 2D configuration resembling an infinity symbol, and at least one electrode mounted on the member. The 2D configuration resembles a first loop and a second loop, wherein the first and second loops are side-by-side, generally extending in a common plane.
