ABSTRACT:
A recording/ablation system includes an inner working catheter for deployment from a distal port in an outer sheath or catheter in a heart chamber, or the like, which has a plurality of divergent electroded spines each constrained at the proximal end with a substantially free distal end for controlled separation. The divergent electroded spines are collapsible to a substantially parallel configuration for transport and stowage. A single deflecting spine version is also disclosed.
