摘要：
A system for sensing multiple local electric voltages from endocardial surface of a heart, includes: a first elongate tubular member having a lumen, a proximal end and a distal end； and a basket assembly including: a plurality of flexible splines for guiding a plurality of exposed electrodes, the splines having proximal portions and distal portions； an anchor for securably affixing the proximal portions of the splines； the anchor being secured at the distal end of the first elongate tubular member； an encapsulated and filament-wrapped distal tip including an encapsulant and a filament for securably affixing the distal portions of the splines in a predetermined angular relationship at the distal tip； wherein the splines comprise a superelastic material； and wherein the basket assembly has a radially expanded non-cylindrical shape.
