Abstract
Methods of making medical devices are described. A method of making a medical device for delivering a bioactive includes preparing a suitable solution comprising the bioactive; placing a vessel containing the solution over a substrate comprising a biocompatible foam and defining open cells; initiating flow of the solution from the vessel and toward the substrate such that the solution exits the vessel and contacts the substrate; and maintaining flow of the solution for an amount of time sufficient to achieve a desired volume of the solution within the substrate. Medical devices made by the methods are also described.
