An apparatus and method of controlling the flow of hydrocarbons into and/or out of a string of tubing disposed in a wellbore. In one embodiment, the apparatus comprises a tubular member having at least one aperture formed in a wall thereof and a sleeve disposed radially outward of the tubular member. The sleeve is selectively movable between a first position and a second position to control the flow between the outside and the inside of the tubular member. In one aspect, the apparatus further comprises a biasing member disposed adjacent the sleeve and adapted to apply a force against the sleeve in an axial direction and further comprises a piston adapted to receive a hydraulic pressure to move the sleeve against the force of the biasing member. In another aspect, the apparatus further comprises a electromechanical device adapted to selectively move the sleeve between the first position and the second position and further comprises a control line adapted to conduct an electrical current. In another embodiment, the apparatus comprises a tubular member having at least one aperture formed therein and a fixed ring and a rotatable ring disposed radially outward of the tubular member. In still another embodiment, the apparatus comprises a plurality of annular ribs having an inner surface, at least one support rod disposed along the inner surface of the annular ribs, and at least one control line disposed along the inner surface of the annular ribs.
