摘要： An implantable medical device has an outer stent with a tubular body disposed about a longitudinal axis. The outer stent includes members defining openings which are in fluid communication with a flow path. At least one opening is larger than adjacent openings when the outer stent is in an expanded state, and is positioned between the ends of the outer stent. The at least one larger opening is a side branch opening having a perimeter. The device also has an inner stent with a tubular body disposed within the outer stent and about a longitudinal axis. The inner stent has a branch portion with deployable petals positioned adjacent to the side branch opening of the outer stent. The petals are biased against the perimeter of the side branch opening such that the petals are restrained from opening outward when the outer stent is in an unexpanded state.

摘要： The embodiments described herein relate generally to medical devices that are useful for delivering one or more therapeutic agents to a body tissue of a subject, and methods for making and using such devices. In particular, the embodiments relate to a medical device such as a stent having a sidewall structure comprising a plurality of struts, in which one or more therapeutic agents are released from different surfaces of the struts at different release profiles. More particularly, the embodiments relate to a stent having a sidewall structure comprising a plurality of struts, in which the two side surfaces of each strut are coated with a coating composition that is different from the coating composition used to coat the outer surface and/or inner surface of the strut.

摘要： According to one aspect of the invention, a method of forming a medical device is provided, which includes: (a) contacting a substrate with a solution that contains (i) one or more types of polymers, (ii) a solvent that contains one or more types of solvent species, and (iii) one or more optional agents, for example, one or more therapeutic agents, among others; and (b) removing the solvent from the solution, thereby forming a polymeric layer on the substrate. The composition of the solution is changed over the course of forming the polymeric layer. In another aspect of the invention, a medical device is provided, which includes a substrate and a polymeric layer over the substrate. The polymeric layer contains a copolymer that contains differing first and second monomers. The lower surface of the polymeric layer contacting the substrate has a surface concentration of the first monomer relative to the second monomer that is higher than that of the upper surface of the polymeric layer opposite the substrate.

摘要： Catheter devices having an expandable balloon for delivering a therapeutic agent to a body site. The balloon has one or more folds which serve as a reservoir for containing the therapeutic agent. The fold may have any of various configurations to hold the therapeutic agent. In some cases, the balloon comprises one or more lobes that forms the fold(s). The therapeutic agent may be provided in various ways. For example, the therapeutic agent may be contained in packets that rupture upon expansion of the balloon, or as a plurality of discrete bulk masses, or sealed within compartments.
