In one embodiment, a kit includes a base and a specimen removably couplable to the base. A top plate defines a plurality of apertures and is removably couplable to the base such that at least two of the apertures are associated with a specimen and each aperture defines a well with that specimen. Each well is configured to receive a sample material therein in contact with the specimen. A method includes disposing a specimen within a recessed portion of a test apparatus and coupling a top plate of the test apparatus to a base of the test apparatus such that a sealing engagement is formed between the top plate and the specimen. The top plate defines a plurality of apertures, each of at least two of the apertures collectively with the specimen defines a well. A sample material can be disposed within at least one well.

According to one aspect of the invention, implantable or insertable medical devices are provided which can delay release of one or more therapeutic agents for a predetermined time after implantation in a subject. In various embodiments, a therapeutic agent delivery profile of this type is provided by employing a temporary barrier layer which initially permits little to no release of the therapeutic agent, but which layer permits much greater release levels after a predetermined period of time. Other aspects of the invention relate to methods of forming such devices and to methods of using such devices.
