Patent ID: 8882705

Claim:
A steerable catheter comprising: an elongated, flexible tubular catheter body having proximal and distal ends and a lumen extending therethrough; a tip section at the distal end of the catheter body, the tip section comprising a flexible plastic tubing having a pair of diametrically-opposed lumens extending therethrough; a control handle at the proximal end of the catheter body; first and second puller wires, each extending through one of the pair of lumens in the tip section and through the lumen of the catheter body, each having a proximal end anchored to the control handle and a distal end anchored to the tip section, whereby the puller wires are longitudinally moveable relative to the catheter body to cause deflection of the tip section; and an elongated deflection mechanism extending in the tip section without contacting the first and second puller wires, the deflection mechanism being configured to provide the tip section with in-plane deflection and comprising a plurality of deflection members, wherein either one of the plurality of deflection members has a proximal end at a different location than a proximal end of another of the plurality of deflection members or one of the plurality of deflection members has a distal end at a different location than a distal end of another of the plurality of deflection members.
