A steerable catheter is disclosed, having an elongated, tubular catheter body with at least one deflection member slidably disposed within a lumen, secured at a distal end to a tip section and terminating in an interconnect at a proximal end and a handle releasably attached to the proximal end of the catheter body. The handle has at least one sliding member coupled to an actuator, such that manipulation of the actuator causes relative longitudinal movement with respect to the handle, wherein the interconnect and the sliding member engage when the handle is attached to the catheter body so that the relative longitudinal movement of the sliding member is transmitted to the deflection member and wherein the interconnect and the sliding member disengage when the handle is released from the catheter body.
