摘要： An implantable and refillable device for delivering a contraceptive agent is provided. The device comprises a reservoir within which the contraceptive agent is capable of being retained, wherein the reservoir defines a first surface and a second surface opposing the first surface. A release structure comprising a hydrophobic polymer surrounds at least a portion of the reservoir. The release structure is in communication with the reservoir such that the contraceptive agent can pass from the reservoir through the release structure. A septum is positioned adjacent to the first surface of the reservoir and a backing layer is positioned adjacent to the second surface of the reservoir.
