Abstract
A method of applying a universal coating for a medical device comprising a medical device component, the medical device component having an outer surface and an inner surface, the universal coating applied to at least the outer surface or the inner surface of the medical device component, wherein the coating is made from a material selected from the group consisting of diamond, diamond-like, borosilicate glass, carbides and nitrides. The medical device can further be a smart medical device by incorporating a sensor placed capable of measuring chemical and/or electrical conditions. A method of applying the coating inside complicated 3D structures without the need for bonding diamond to diamond or DLC to DLC layers is also provided.

A method of manufacture of a medical device, comprising:
- depositing a diamond-like coating or other optically clear film on a p-type silicon wafer;
- masking desired areas using suitable masking material or thermally growing SiO2 to create a pattern for desired optical windows;
- anisotropically etching until reaching the diamond-like coating film;
- and
- stripping the masking material or thermally grown SiO2.
A method of manufacture of a medical device, comprising:
- (a) fabricating a removable three dimensional structure, the removable three dimensional structure made from a low melting point or chemically dissolvable material;
- (b) depositing a universal coating onto the removable three dimensional structure, the universal coating selected from the group consisting of diamond, diamond-like, borosilicate glass, carbides, and nitrides;
- (c) applying a support structure to the universal coating;
- (d) forming an opening in the support structure and the universal coating;
- and
- (e) removing the removable three dimensional structure.
A method of manufacture of a medical device, comprising:
- (a) fabricating a three dimensional structure substrate out of a low melting point material using a micromolding process;
- (b) depositing a film selected from the group consisting of diamond-like or silicon material to completely cover the substrate;
- (c) creating at least one opening out of the structure;
- and
- (d) melting the low melting point material.
A method of manufacture of a medical device, comprising:
- (a) fabricating a three dimensional structure substrate out of a chemically dissolvable material using a micromolding process;
- (b) depositing a film selected from the group consisting of diamond-like or silicon material to completely cover the substrate;
- (c) creating at least one opening out of the structure;
- and
- (d) dissolving the chemically dissolvable material.
