PROBLEM TO BE SOLVED: To provide an electrophysiologic catheter.SOLUTION: A catheter comprises: an elongated catheter body; a deflectable section distal to the catheter body; a tip electrode distal to the deflectable section; and a contact force sensor between the deflectable section and the tip electrode. The contact force sensor comprises: a cup shaped body having a cylindrical wall; a plurality of radially extending spokes formed integrally with the body; a beam member; and at least one strain gage mounted on one of the plurality of radially extending spokes, the plurality of radially extending spokes converging at a location on the body from which the beam member extends. An end of the beam member is connected to the tip electrode. |
