    摘要: An implantable medical device for the release of bioactive agents at desired rates is described. The device includes a body member with two or more aperture sets and an inner space. The bioactive agents are arranged within the inner space of the body member so that each bioactive agent present in the inner space is individually releasable through their respective aperture set. The aperture sets modulate the release of the bioactive agents from the body member. Arrangement of apertures and bioactive agents within the inner portion chosen to provide desired and independent release rates from the device.
