Abstract: Systems and method for using a sleeve for enhanced drug delivery are described. The sleeve may incorporate porous materials and may be coated or treated with various drugs and/or therapeutic agents. The sleeve may be utilized in cooperation with balloon catheters and/or other devices. When acting as a reservoir for holding various drugs and/or therapeutic agents, the drug delivery sleeve provides a means of reducing drug losses as well as a controlled mechanism for drug release. The materials for the sleeve, constructed by various techniques, may be circumferentially distensible, may be elastic, and may have varying degrees of recoil as needed for any particular purpose.
