Abstract
A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.
