Abstract
An electrode catheter used in an endocardial procedure to map cardiac electrical activity, heart wall position, heart wall motion and tissue viability. The electrode catheter has a flexible geometric shape for mapping any cardiac chamber and can be rotated within the chamber without being re-deployed. The electrode catheter is made from joining a tube with 4 to 256 wire leads having terminal ends and coiled electrodes. The tube either has holes or a longitudinal slit so that the coiled electrodes can protrude from the central cavity of the tube. The electrode catheter ends with a tip member that is attached to the tube by a swivel connector. The tip member has tines to allow for temporary stability when in contact with a cardiac wall. The electrode catheter is conformed to a flexible shape using a jig and heating process.
