Abstract
A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode array with offset spine loops, each spine loop having at least a pair of linear portions and a distal portion connecting the pair of linear portions, and one or more electrodes on each linear portion. The linear portions of the plurality of offset spine loops are arranged in-plane a single common plane, and the distal portions of the plurality of offset spine loops are arranged off-plane from the single common plane.

A catheter comprising:
- an elongated catheter body having a distal end;
- and
- a distal electrode array mounted on the distal end of the catheter body, the distal electrode array comprising a plurality of offset spine loops, each spine loop having at least a pair of electrode-carrying portions and a distal portion connecting the pair of electrode-carrying portions, wherein the electrode-carrying portions of the plurality of offset spine loops lie in a single common plane, and the distal portions of the plurality of offset spine loops are angled out of the single common plane.
A catheter comprising:
- an elongated catheter body having a distal end;
- a distal electrode array mounted on the distal end of the catheter body, the distal electrode array comprising a plurality of offset spine loops, each spine loop having at least a pair of linear portions and a distal portion connecting the pair of linear portions, and
- one or more electrodes on each linear portion,
- wherein the linear portions of the plurality of offset spine loops lie in a single common plane, and the distal portions of the plurality of offset spine loops are angled out of the single common plane.
