FLEXIBLE MULTIPLE-ARM DIAGNOSTIC CATHETER

摘要

PROBLEM TO BE SOLVED: To provide a medical probe which includes a distal end and an elongate body for insertion into an organ of a patient.SOLUTION: A medical probe 22 includes a distal end 40 and an elongate body for insertion into an organ 26 of a patient 28. The distal end is connected to the elongate body and includes multiple arms that, when inserted into the organ, extend to form multiple respective spirals each having electrodes disposed thereon. The organ comprises a heart, and the electrodes comprise electrophysiological (EP) mapping electrodes. Each of the multiple arms is configured to conform to a surface of the organ independently of any other of the arms.
