Summary:A system for sensing multiple local electric voltages from endocardial surface of a heart, includes: an elongate tubular member having a lumen, a proximal end and a distal end; and a basket assembly including a plurality of flexible splines; an anchor for securably affixing proximal portions of the splines, where the anchor is securably affixed within the lumen of the elongate tubular member at the distal end of the elongate tubular member; and a tip for securably affixing the distal portions of the splines; where the tip is recessed within the basket assembly upon radial expansion of the basket assembly.
