Abstract
Scaffold-supported metal or pseudometallic film covers suitable for use as medical devices are disclosed together with methods of fabricating the devices. Methods for making the medical devices consist of either providing or forming a scaffold, then depositing a metallic or pseudometallic film cover onto the scaffold in such a manner as to form an integral, substantially monolithic junction between the deposited cover material and the scaffold.
Claims22
A method of making a medical device having a covered scaffold, comprising the steps of:
- a) Forming a scaffold 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;
- c) Creating a plurality of openings passing through the cover-forming material;
- and
- d) Releasing the monolithically joined scaffold and cover-forming material from the deposition substrate.
A method of making a medical device having a structural scaffold and a cover, comprising the steps of:
- a) Providing a substrate suitable for vacuum deposition of biocompatible metals and pseudometals thereupon, the substrate having a pattern imparted thereto corresponding to the structural scaffold;
- b) Vacuum depositing a scaffold-forming biocompatible metal or pseudometal onto the substrate and into the pattern;
- c) Planarizing the scaffold-forming biocompatible metal or pseudometal to a surface of the substrate such that at least a portion of the scaffold-forming biocompatible metal or pseudometal in the pattern is substantially co-planar with the surface of the substrate;
- d) Vacuum depositing a cover-forming biocompatible metal or pseudometal onto the substrate and the scaffold-forming biocompatible metal or pseudometal;
- e) Forming a plurality of openings in the deposited cover-forming biocompatible metal or pseudometal;
- and
- f) Removing the substrate from the deposited scaffold-forming and cover-forming biocompatible metals or pseudometals.
