Abstract: Devices, systems and methods are used to decouple proximal movement of a catheter supply lead or tubing from the tissue-embedded catheter. A catheter decoupling device comprises a catheter hub, sled and track, wherein the hub comprises a proximal end configured to receive a catheter fluid supply device, and a distal end configured to receive a catheter, the sled receives and retains the hub, the track receives and retains the hub; and, the hub has a limited range of back-and-forth motion relative to the track.

Abstract: The invention relates to medical devices and, particularly, catheter medical devices. In an aspect is a nerve block catheter system comprising a dual-sheath catheter comprising an inner sheath and an outer sheath, wherein distal ends of the sheaths are connected, the inner sheath defines a fluid delivery lumen, and the outer sheath comprises a tissue lock movable between a collapsed position and an extended position, wherein the tissue lock forms a reversible tissue anchor when in the extended position, and an actuator connected to the proximate end of the catheter and configured to activate the tissue lock by sliding the outer sheath length-wise relative to the inner sheath.
