Abstract

An everting catheter system comprising an elongated outer tubular body having an outer body lumen and an opening leading from the outer body lumen, an elongated inner tubular body movable longitudinally in the outer body lumen and having an inner body lumen and an everting element coupled to the outer body and the inner body so that with movement of the inner body longitudinally in the outer body lumen the everting element can be everted and inverted. The system also includes an elongated instrument, such as a transfer catheter, movable longitudinally in the inner body lumen relative to the inner body. A coupling releasably couples the instrument to the outer body in a substantially fixed longitudinal position with respect to the outer body.
