BASKET STYLE CARDIAC MAPPING CATHETER HAVING AN ATRAUMATIC BASKET TIP FOR DETECTION OF CARDIAC RHYTHM DISORDERS |
摘要 |
A system (10) for sensing multiple local electric voltages from endocardial surface of a heart is provided. The system may comprise a first elongate tubular member (20) having a lumen (20C), a proximal end (20A) and a distal end (20B); and a basket assembly (12) comprising: a plurality of flexible splines (14) for guiding a plurality of exposed electrodes (186), the splines (14) having proximal portions (62) and distal portions (66); an anchor (18) for securably affixing the proximal portions (62) of the splines (14); said anchor (18) being secured at the distal end (20B) of the first elongate tubular member (20); an encapsulated and filament -wrapped distal tip (16, 120) comprising an encapsulant (122) and a filament (124) for securably affixing the distal portions (66) of the splines (14) in a predetermined angular relationship at said distal tip (16, 120); wherein the splines (14) comprise a superelastic material; and wherein the basket assembly (12) has a radially expanded non - cylindrical shape. |
