Disclosed herein are coatings for implantable medical device. The coatings comprise a composition, comprising a polymer linked to a chemical moiety through a covalent bond, wherein the chemical moiety forms a pharmaceutically active agent upon degradation (e.g., hydrolysis) of the covalent bond; and transglutaminase substrates.

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.

摘要:
A medical device delivery system includes a self-expanding medical device mounted on a balloon portion of a catheter. A sheath is provided around the medical device to hold the device in place with the device staying in a compressed state. The balloon portion is inflated to cause the sheath to rupture and release the self-expanding medical device. A number of radio- opaque markers in a pattern that will aid in determining whether or not the sheath has properly ruptured upon inflation of the balloon portion are provided on the sheath. The radio-opaque markers are positioned with respect to an expected sheath rupture propagation path along which the sheath is expected to rupture. The pattern of the markers changes as the sheath ruptures and this change is detected by an operator of the system.
