BASKET STYLE CARDIAC MAPPING CATHETER HAVING SPLINE BENDS FOR DETECTION OF CARDIAC RHYTHM DISORDERS
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.
