Abstract: A medical device includes a polymer stent crimped to a catheter having an expansion balloon. The stent is crimped to the balloon by a process that includes heating the stent to a temperature below the polymer's glass transition temperature to improve stent retention without adversely affecting the mechanical characteristics of the stent when later deployed to support a body lumen. A variable diameter sheath with a central portion that prevents expansion of the stent when the balloon is pressurized and larger diameter ends is disposed over the crimped stent-balloon assembly. The balloon is pressurized and the larger diameter ends of the sheath allow the balloon beyond the ends of the stent to expand. The balloon is then depressurized.

Abstract: A method of crimping a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the maker support structures.

Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the peaks that are adjacent the curved portion of the undulating link are shorter than other peaks in the same cylindrical ring to prevent overlap yet still achieve a very low profile, tightly crimped stent onto a catheter.

Abstract: A stent design reduces the likelihood of contact among structural members when the stent diameter is reduced before insertion into the body. In one approach, an undulating link has a J-shaped profile or has an angled portion on one side at the peak of the link, in order to reduce contact during crimping. The stent may also include structural features that improve such aspects as flexibility, the coatibility of a drug coating onto the stent, flare reduction, stent retention within the body and/or reduction of the minimum diameter of the stent during crimping.

Abstract: A therapeutic formulation is described for a drug delivery balloon comprising a therapeutic formulation which includes a therapeutic agent and an adhesion additive. The adhesion additive promotes adhesion of the therapeutic formulation a vessel wall of a subject. A system and a method of manufacturing a system including an expandable member having a working length with the therapeutic formulation disposed along at least a portion of the working length is also provided.

Abstract: A bioscaffolding can be formed within a post-myocardial infarct region sufficient to cause attenuation of a rate of myocardial infarct expansion. A bioscaffolding may further be formed in the post-myocardial infarct region to cause an increase in posterior left ventricular wall thickness. The gel or bioscaffolding can be formed from a mixture of gel components of different gelation systems. For example, a bioscaffolding can be formed by mixing at least two different components of at least two different two-component gelation systems to form a first mixture and by mixing at least two different components (other than the components that make up the first mixture) of the at least two different two-component gelation systems to form a second mixture.

Abstract: Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.
