Abstract:
1. A catheter assembly, including: a handle body; a steering control mechanism displaceably carried on the handle body; an electrode sheath carrier carried on a distal end of the handle body, the electrode sheath carrier being configured for releasable attachment of an electrode sheath to the handle body, and the electrode sheath carrier being axially displaceable between an operational proximal-most position and an operational distal-most position of the electrode sheath carrier relative to the steering control mechanism throughout use of the catheter assembly in the body of a patient to effect axial displacement of the electrode sheath relative to a steering shaft when both a proximal end of the steering shaft and the electrode sheath are attached to the handle body; and an electrode sheath carried by the electrode sheath carrier, the electrode sheath including electrodes in continuous electrical connection with the catheter handle during the axial displacement of the electrode sheath carrier between the operational proximal-most position and the operational distal-most position of the electrode sheath carrier relative to the steering control mechanism.
