Abstract

The invention is titled as asymmetric basket catheter. This disclosure is directed to a catheter having an asymmetric basket-shaped electrode assembly at the distal end of the catheter body formed from a plurality of spines with electrodes. The plurality of spines are radially distributed across a first circumferential portion. One or more counter spines are radially distributed across a remaining second circumferential portion. Diagnostic electrodes are arrayed across the spines, while the counter spines may have one or more reference electrodes.

Description

technical field [0001] The present invention relates to electrophysiology (EP) catheters, in particular, to EP catheters for mapping and / or ablation in the heart. Background technique [0002] Electrophysiology catheters are commonly used to map electrical activity in the heart. Various electrode designs are known for different purposes. In particular, catheters with basket-shaped electrode arrays are known and described, for example, in U.S. Patents 5,772,590, 6,748,255, and 6,973,340, the entire disclosures of each of which are incorporated herein by reference for use in patients In the chambers or similar areas of the heart. [0003] Basket catheters typically have an elongated catheter body and a basket electrode assembly mounted at the distal end of the catheter body. The basket assembly has a proximal end and a distal end, and includes a plurality of ridges distributed around a circumference and connected at the proximal and distal ends thereof. Each ridge includes...
