  • Patent number: 9358096
    Abstract: A drug eluting stent can include a stent body having a polymeric coating with a lipophilic and/or hydrophilic element. A drug that has a bioactivity that inhibits cell proliferation can be disposed in the polymeric coating. The drug can be present in the polymer at an amount greater than or equal to about 150 ?g/cm2. The polymeric coating and drug are configured to cooperate so as to form a diffusion pathway with tissue when the stent is disposed in a body lumen such that the drug preferentially diffuses into the tissue over a body fluid passing through the body lumen such that a maximum systemic blood concentration of the drug is less than about 40 ng/ml.

  • Publication number: 20150112425
    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.
