CATHETER DEFLECTION ANCHOR

摘要

A system (10) and method for anchoring a round catheter pull wire (24) within the distal end (18) of a catheter. A steering deflection mechanism (12) includes a pull ring (38) having a plurality of apertures (42a, 42b, 42c) and one or more receiving slots (40). The method includes affixing one or more round pull wires to the one or more receiving slots of the pull ring. The shape of the round wire and manner of affixing the wire to the pull ring provide a steering assembly that can withstand greater pull forces while maintaining design integrity.
