An apparatus is configured to be implanted within a biological structure. The apparatus includes a plurality of magnetic elements, an absorbable component, and a non-absorbable component. The plurality of magnetic elements are configured to transition the biological structure between an occluded state and an opened state. The plurality of magnetic elements are biased to encourage the biological structure toward the occluded state. The absorbable component includes a therapeutic substance. The absorbable component is configured to temporarily couple the plurality of magnetic elements with the biological structure when the apparatus is initially implanted within the biological structure.
