Abstract:
1. A method of making a medical device having a covered scaffold, comprising the steps of: a) Forming a plurality of structural scaffold members with an interstitial area between the plurality of structural scaffold members in association with a deposition substrate; b) Depositing a cover-forming material onto the formed scaffold, thereby monolithically joining the scaffold and the cover-forming material; disposing a second scaffold member onto the cover-forming material; depositing a sacrificial material onto the second scaffold member and the cover-forming material; removing portions of the sacrificial material to expose portions of the second scaffold member; depositing a second cover-forming material onto the exposed portions of the second scaffold member and the sacrificial material; c) Creating a plurality of openings passing through the cover-forming material and over the interstitial area; creating a plurality of openings in the second cover-forming material that do not overlie the second scaffold member; and d) Releasing the monolithically joined scaffold and cover-forming material from the deposition substrate; removing the sacrificial material to form a void plenum between the cover-forming material and the second-cover forming material; and loading at least one pharmacologically agent into the void plenum between the cover-forming material and the second cover-forming material.
