    摘要： A grafting reagent and related method of using the reagent to form a polymeric layer on a support surface, and particularly a porous support surface, in a manner that provides and/or preserves desired properties (such as porosity) of the surface. The reagent and method can be used to provide a thin, conformable, uniform, uncrosslinked coating having desired properties onto the surface of a preformed, and particularly a porous, polymeric substrate. The method includes the steps of a) providing a porous support surface, b) providing a nonpolymeric grafting reagent comprising a photoinitator group, c) providing one or more polymerizable monomers adapted to be contacted with the surface, in the presence of the grafting reagent, and to be polymerized upon activation of the photoinitiator; and d) applying the grafting reagent and monomer(s) to the surface in a manner, and under conditions, suitable to coat the surface with the grafting reagent and to cause the polymerization of monomers to the surface upon activation of the grafting reagent.

    摘要： 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.

    摘要： A method for coating a rollable device including a device rotator having a pair of rollers and spray nozzle is described. The spray nozzle produces a spray of coating material that is directed towards a gap that is between the rollers of the pair. The majority of any spray not deposited on the rollable device during a coating process passes through the gap between the rollers.
