US Classification:

427 23, 118 58
Abstract:

Method of coating an expandable member is provided. The method comprises providing an expandable member having deflated and fully expanded configurations, and inflating the expandable member with a select amount of inflation medium, the select amount of inflation medium applied at a nominal pressure, disposing a therapeutic agent on at least a portion of the expandable member; and partially deflating the expandable member, wherein partially deflating includes releasing an initial amount of inflation medium from the expandable member such that the expandable member partially re-folds. The therapeutic agent can be dried on the expandable member, and a remaining amount of inflation medium can be withdrawn such that the expandable member resumes the completely folded configuration.
