Abstract
A system a system for sensing multiple local electric voltages from endocardial surface of a heart, includes: a first elongate tubular member; a basket assembly including: a plurality of flexible splines for guiding a plurality of exposed electrodes, the splines having proximal portions, distal portions and medial portions therein between; a proximal anchor for securably affixing the proximal portions of the splines; the proximal anchor being secured at the distal end of the first elongate tubular member; a distal tip for securably affixing the distal portions of the splines wherein at least some of the splines in the radially expanded non-spherical shape contain a distal excurvate outward bend disposed at the distal portion of the spline at a location near to the distal tip of the basket assembly to bend the splines back towards the proximal anchor.
