A rotatable connection between a tubular member and an elongate wire of a catheter for allowing rotational movement of the tubular member relative to the elongate wire. The rotatable connection includes a first tube secured to the tubular member and a second tube secured to the elongate wire. The second tube is disposed around the first tube and rotatable relative to the first tube. The longitudinal axis of the tubular member is offset from the longitudinal axis of the elongate wire to allow a guidewire to extend through the tubular member and along the side of the elongate wire.
