Abstract
The invention features an empty device for receiving a bioactive agent. The device includes a biocompatible and semi-permeable membrane that defines an enclosed space; the membrane also has at least one end that defines an opening for introducing the bioactive agent into the enclosed space. The device is configured to be placed in an animal. In one embodiment of the invention, the membrane has an inner surface and an outer surface, where the inner surface defines the inner surface, and includes a biocompatible adhesive in the general region of the opening to allow sealing of the opening after the introduction of the bioactive agent into the enclosed space. Another embodiment of the invention includes a biocompatible frame mounted in supporting relationship to the membrane and defining an opening for introducing the bioactive agent into the enclosed space. The frame has greater porosity than the membrane.
