| 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.
