Abstract

A pre-curved steerable catheter includes a catheter body (102) having a distal end portion. The distal end portion includes a permanently curved flexible end portion (110). A pull wire (108) is disposed in a pull wire lumen within the catheter body. The pull wire extends from the distal end portion to a proximal end portion of the catheter body wherein the pull wire, when tensioned, provides a change in an angle of the curved flexible end portion of the catheter body.
