Abstract

A catheter having a basket-shaped electrode assembly at the distal end of the catheter body formed from a plurality of spines with electrodes. The plurality of spines are formed by a framework which is prestrained to have a diameter greater than the diameter of the expanded arrangement of the basket-shaped electrode assembly and a length less than the length of the expanded arrangement of the basket-shaped electrode assembly.

Description

Technical field [0001] The invention relates to an electrophysiological (EP) catheter for mapping and / or ablation in the heart. Background technique [0002] Nowadays, a cardiac catheter including an electrophysiological sensor for mapping the electrical activity of the heart is often used to perform the mapping of the electrical potential in the heart. Usually, the time-varying electric potential in the endocardium is sensed and recorded according to the position in the heart, and then used to map the local electrogram or local activation time. Due to the time required to conduct electrical pulses through the myocardium, the activation time of each point in the endocardium is different. The direction of this electrical conduction at any point in the heart is conventionally represented by an activation vector, which is perpendicular to the isoelectric activation wavefront, both of which can come from a map of activation time. The propagation velocity of the active wavefront thr...
