Abstract
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.
Claims20
A catheter comprising:
- an elongated catheter body;
- a distal section distal the catheter body and having a flexible elongated member with shape memory, the member being configured to assume a 2D configuration comprising a first loop in a first direction and a second loop in a second direction opposite the first direction, the 2D configuration terminating in a free distal end of the member;
- and
- at least one electrode mounted on the member.
A catheter comprising:
- an elongated catheter body having a longitudinal axis;
- a distal section distal the catheter body and having at least first and second flexible elongated members with shape memory, the at least first and second flexible elongated members being configured to assume a 2D configuration resembling an infinity symbol, wherein the first elongated member is configured to form a first loop terminating in a first free distal end of the first elongated member and the second elongated member is configured to form a second loop terminating in a second free distal end of the second elongated member, the first and second loops being side-by-side in a common plane and having an intersection, the first and second free distal ends being generally at the intersection, and the common plane of the first and second loops being at an angle relative to the longitudinal axis of the catheter body;
- and
- at least one electrode mounted on each of the first and second members.
A catheter comprising:
- an elongated catheter body;
- a distal section distal the catheter body and having a flexible elongated member with shape memory, the member being configured to assume a 2D configuration with a first loop in a first direction and a second loop in the first direction, the 2D configuration terminating in a free distal end of the member;
- and
- at least one electrode on the member.
