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

摘要

PROBLEM TO BE SOLVED: To provide devices, systems and methods for the detection of cardiac rhythm disorders by use of a percutaneous catheter designed to permit acquisition of numerous, simultaneous endocardial electrograms from a three dimensional array of surface electrodes.SOLUTION: A system according to the present invention comprises: an elongate tubular member 20; a plurality of flexible splines 14; a polymeric member 185 for defining an open lumen between a first open end and a second open end which are opposing to each other, at least one of the plurality of flexible splines 14 being at least partially disposed within the lumen of the polymeric member; and a flexible electrode assembly strip with one or more exposed electrodes 186 disposed on at least a portion of the outer surface of the polymeric member 185. One portion of the flexible electrode assembly moves from the outer surface of the polymeric member 185 toward the inner surface of the polymeric member 185.
