Assemblies for creating compound curves in distal catheter regions
First Claim
1. A steerable catheter comprisingan elongated catheter body having a distal end, anda single steering assembly carried by the distal end of the catheter tube includinga first steering mechanism for creating a first bend in the distal end of the catheter body, said first bend defining a first bending plane, said first steering mechanism further including first and second steering wires adapted to control said first bend, anda second steering mechanism for creating a second bend in the distal end of the catheter body, said second bend defining a second bending plane, which is non-parallel to the first bending plane, said second steering mechanism further including third and fourth steering wires adapted to control said second bend.

Abstract
Compound steering assemblies, usable in both diagnostic and therapeutic applications, enable a physician to swiftly and accurately steer the distal section of the catheter in multiple planes or complex curves to position and maintain ablation and/or mapping electrodes in intimate contact with an interior body surface.

11. A steerable catheter comprising
an elongated catheter body having a distal end, and a single steering assembly carried by the distal end of the catheter tube including a first steering mechanism for bending the distal end of the catheter body in a first bending plane, said first steering mechanism including first and second steering wires, and a second steering mechanism for bending the distal end of the catheter body in a second bending plane, which is non-parallel to the first bending plane, said second steering mechanism including third and fourth steering wires, and wherein the first steering mechanism comprises a preshaped wire biased to bend the distal end of the catheter into a curvilinear shape in the first bending plane.
