F40 with 20x objective
There are many types of coatings used in the manufacturing and preparation of biomedical devices. Some coatings protect the device from corrosion while others protect from complications such as tissue trauma, infection, or even rejection. Drug delivery coatings are also becoming common. Other biomedical devices, including angioplasty balloons, are freestanding membranes that must be of uniform and fixed thickness in order to function properly.
Thickness measurement methods of these coatings vary, but one thing is certain - the most commonly used methods (such as weighing a part before and after coating) do not detect incomplete coverage or coating non-uniformities that can lead to device failure.
Filmetrics offers a broad range of solutions for measuring coated biomedical devices:

Stents are small tubes made of plastic or metal which are inserted within blood vessels to prevent constriction. Many times, these stents are treated with a polymer or drug coating to enhance functionality and corrosion-resistance. Using our F40 instrument along with 20x objective (25µm spot size), we are able to measure the thickness of these coatings along the outer diameter of a stainless-steel stent. This powerful instrument offers those in the medical device industry a system capable of fast and reliable thickness measurements that is non-destructive and requires no sample preparation.
