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.

Abstract: A registration device includes an attachment piece (106) configured to conform with and attach to an imaging probe (102), in particular an internal or external ultrasound probe such as a TEE probe. A pathway (105) formed in or on the attachment piece is configured to receive an optical shape sensing device (OSS fiber) such that the optical shape sensing device can free float (no tip fixation) to permit longitudinal twisting within the pathway. The pathway includes a distinctive geometry for shaping the OSS device such that the distinctive geometry provides a template pattern (107) within an image collected using the imaging probe module to permit registration between imaging coordinates and OSS coordinates. A registration module (130) is configured to compare a stored shape template (121) with an image (134) including the template pattern to permit the registration (unique transformation).
