Abstract:
A medical device comprises a supporting structure capable of containing or supporting a pharmaceutically acceptable carrier or excipient, which carrier or excipient may contain one or more therapeutic agents or substances, with the carrier preferably including a coating on the surface thereof, and the coating containing the therapeutic substances, such as, for example, drugs. Supporting structures for the medical devices that are suitable for use in this invention include, but are not limited to, coronary stents, peripheral stents, catheters, arterio-venous grafts, by-pass grafts, and drug delivery balloons used in the vasculature. Drugs that are suitable for use in this invention include, but are not limited to drugs of Formula (I). The drugs of Formula (I) can be used in combination with another drug including those selected from anti-proliferative agents, anti-platelet agents, anti-inflammatory agents, anti-thrombotic agents, cytotoxic drugs, agents that inhibit cytokine or chemokine binding, cell de-differentiation inhibitors, anti-lipaedemic agents, matrix metalloproteinase inhibitors, cytostatic drugs, or combinations of these drugs.
Abstract:
System for treating vascular disease comprising a balloon having an outer surface for temporary contact with a vessel wall when in an expanded state, a coating disposed on at least a portion of the outer surface, the coating including an initial amount of a cytostatic agent selected from the group consisting of Zotarolimus (ABT578), everolimus, pimecrolimus, and a combination thereof, the coating being capable of maintaining a therapeutically effective amount of the cytostatic agent on the outer surface for delivery to a vessel wall, and further wherein between about 4.9% to about 23% of the initial amount of the cytostatic agent on the outer surface remains disposed on the outer surface after delivery of the therapeutically effective amount of the cytostatic agent to the vessel wall, and optionally, a stent disposed on the balloon.

Abstract:
A method for improving the retention between the surfaces of medical devices. The method includes coating a surface of one medical device such as a stent with a coating that includes a functional group and coating a surface of another medical device such as a balloon with a coating that includes an identical or different functional group. The method further includes interacting the coated surfaces to produce a plurality of bonds between the surfaces, thereby improving retention.
Abstract:
An apparatus and system for delivering a lipophilic agent associated with a medical device including: a medical device, a first lipophilic agent capable of penetrating a body lumen, wherein the transfer coefficients of the first lipophilic agent is by an amount that is statistically significant of at least approximately 5,000, wherein the first lipophilic agent is associated with the medical device, wherein the first lipophilic agent/medical device is placed adjacent to said body lumen, and wherein a therapeutically effective amount of the first lipophilic agent is delivered to a desired area within a subject. Furthermore, the invention relates to a method for improving patency in a subject involving placement of a medical device in a body lumen for treating and/or preventing adjacent diseases or maintaining patency of the body lumen.
