Abstract
A steerable catheter including a handle and a catheter tube, the tip of which may be selectively curved by the operator to assume a pre-programmed curved shape in three dimensions. A single elongated, substantially flat planar shim is mounted within the tip of the catheter tube. The shim has at least one transverse or lateral twist which causes the tip of the catheter tube to assume a curvature in more than one plane when the catheter is operated by manipulation of the remotely positioned handle.
