BASKET STYLE CARDIAC MAPPING CATHETER HAVING A FLEXIBLE ELECTRODE ASSEMBLY FOR DETECTION OF CARDIAC RHYTHM DISORDERS

摘要

A system (10) for sensing multiple local electric voltages from endocardial surface of a heart, may comprise: an elongate tubular member (20); a plurality of flexible splines (14); a polymeric member (185) comprising opposed a first open end (202) and a second open end (200) defining an open lumen (208) therein, wherein at least one of the plurality of flexible splines (14) is at least partially disposed within the lumen (208) of said polymeric member; a flexible electrode assembly strip (188) with one or more exposed electrodes (186) disposed on at least a portion of the outer surface (208A) of said polymeric member (185); wherein a portion of the flexible electrode assembly (188) transitions from the outer surface (208A) of said polymeric member (185) towards the inner surface (208B) of said polymeric member (185).
