  • Patent number: 9795720
    Abstract: Aspects herein relate to coatings with crystallized active agent(s) and related methods. A method for coating a medical device herein includes selecting a solvent and a polymer, selecting a concentration of an active agent of at least a certain amount of saturation, forming a coating composition having the selected concentration of the active agent, and applying the coating composition to the medical device.
    Type: Grant
    Filed: July 15, 2016
    Date of Patent: October 24, 2017

  • Patent number: 9649413
    Abstract: Embodiments herein include coatings with crystallized active agent(s) and related methods. In an embodiment, a method is included for coating a medical device including selecting a solvent and a polymer, selecting a concentration of an active agent of at least a certain amount of saturation, forming a coating composition having the selected concentration of the active agent, and applying the coating composition to the medical device. In an embodiment, an elution control coating disposed on a medical device is included, the elution control coating including an active agent that is at least about 80% crystallized within one week of being disposed on the medical device. In an embodiment, a method is included for enhancing the formation of active agent crystals within a coating layer including adjusting the concentration of an active agent in a coating solution to reach some percentage of the active agent saturation point.

  • Patent number: 9427501
    Abstract: Coatings with crystallized active agent(s) and related methods are disclosed. One method includes selecting a solvent and a polymer, selecting a concentration of an active agent of at least a certain amount of saturation, forming a coating composition having the selected concentration of the active agent, and applying the coating composition to the medical device. Also disclosed is an elution control coating which includes an active agent that is at least about 80% crystallized within one week of being disposed on a medical device. One method enhances the formation of active agent crystals within a coating layer by adjusting the concentration of the active agent in the coating solution to reach some percentage of the active agent saturation point. Another method includes increasing the rate of active agent nucleation within the coating.

  • Publication number: 20040044404
    Abstract: A coating composition, in both its uncrosslinked and crosslinked forms, for use in increasing the static friction of a surface of a delivery system comprising a medical device having a surface in contact with the surface of a delivery component, the static friction of the surface being increased in an amount sufficient to substantially maintain the position of the medical device on the delivery component against forces asserted on the delivery system as it navigates through a vessel of the body. The delivery system may comprise a balloon catheter as the delivery component and a stent as the medical device. A composition includes a polyether monomer, such as an alkoxy poly(alkylene glycol), a carboxylic acid-containing monomer, such as (meth)acrylic acid, optionally a photoderivatized monomer, and a hydrophilic monomer such as (meth)acrylamide.
