Abstract
A reservoir system for a flexible, elongated, body implantable member of the type that is adapted to provide communication between separated body sites. A reservoir body is formed of a cup and cover which cooperate to define a cavity. Slots in the cup and/or cover admit a portion of the elongated member into the cavity. A tool is engageable with an elongated member portion within the cavity to coil a desired length of the elongated member within the cavity. On growth of the body, the coil is uncoiled to accommodate the greater distance between the body sites between which the elongated member extends. In a preferred embodiment, the tool is first rotated in one direction to coil a desired length of the elongated member within the cavity and then rotated in the other direction to uncoil and recoil all but a portion of the outermost coil spiral.
