Abstract
An electrophysiology catheter is provided. In one embodiment, the catheter includes an elongate, deformable shaft having a proximal end and a distal end and a basket electrode assembly coupled to the distal end of the shaft. The basket electrode assembly has a proximal end and a distal end and is configured to assume a compressed state and an expanded state. The electrode assembly further includes one or more tubular splines having a plurality of electrodes disposed thereon and a plurality of conductors. Each of the plurality of conductors extends through the tubular spline from a corresponding one of the plurality of electrodes to the proximal end of the basket electrode assembly. The tubular splines are configured to assume a non-planar (e.g., a twisted or helical) shape in the expanded state.
