The present invention discloses a system for releasing one or more therapeutic agents contained within a capsule onto or into an implant. At least one capsule is inserted in a recess preferably located along a longitudinal axis of the implant. The at least one adhesive capsule may be inserted in the recess and held in place therein by a holder. A plurality of adhesive capsules and holders may be inserted in one or more recesses located substantially along the longitudinal axis of the implant. The at least one capsule preferably has a casing housing one or more therapeutic agents, wherein the capsule is configured to be pierced by the at least one fastener to release the one or more therapeutic agents. The casing of the capsule may form an annular passageway to receive a guide wire for aiding the insertion of the capsule in an implant having a longitudinal bore along at least a portion thereof.
