Hydrophilic Coatings

Hydrophobic, Silicone-Based Coatings

Titanium Nitride (TiN) Coatings

A distinctive product for medical device applications, this is a true ionic hydrophilic coating. Unlike competitive products, it does not add rigidity or significant thickness to your device (coating thickness ranges from 0.0000125” to 0.0003”). In the dry state, this coating will increase lubricity by approximately 90%, while in a fluid environment lubricity will increase by as much as 200%. Either inner or outer surfaces may be coated.

The coating is gamma, E-beam and ETO sterilizable, meets Class VI biocompatability criteria and is produced by an FDA registered manufacturer. Both rapid-turn contract coating and licensing for in-house use are available.

Highly effective, lubricious coatings based on a specially formulated, high viscosity, pure Dow Corning silicone. Depending on the application, lubricity after coating can surpass that achieved by PTFE coatings. There are several formulations covering most metallic and polymeric surfaces. Heparin loaded formulations are available. Either inner or outer surfaces may be coated.

The coatings are gamma, E-beam and ETO sterilizable, meet Class VI criteria and are produced by an FDA registered manufacturer. Both quick-turn contract coating and licensing for in-house use are available.

For metal implants, burrs, drills, blades, electrosurgical paddles and all types of medical and industrial applications. Offers outstanding wear resistance and improves ease of cutting. Super hard and corrosion resistant, TiN coatings feature non-stick properties and eliminate galling and seizing where metal-on-metal contact is necessary. A metallic gold appearance is typical, but other colors are available.

Radiopaque Coatings

Ceramic Coatings

Anti-Microbial Coatings

Radiopaque coatings are applied to medical devices as markers. The proprietary coating absorbs x-rays, making treated catheters, stents, and other devices easily visible with fluoroscopy. These radiopaque coatings eliminate the need for electroplated, crimped, or swaged metal bands that can be abrasive, loosen, crack, or fall off. The coatings are a combination of noble metals, and can be applied in any pattern.

Insulating and load bearing Alumina and Zirconia are coated on surfaces through several techniques, including microfusion and high-energy reactive ion implantation. Insulating films are used to provide inter/over layers for thin film circuitry. Applications include thermocouples, EP sensing and therapeutic leads. Load-bearing coatings are used for articulating surfaces such as artificial joints. The ceramic provides a tough, extremely smooth and fracture free coating.

Employing the germ-fighting properties of silver, this process involves growing multiple layers of silver-based coatings on catheters and other devices. Applied through an unbalanced magnetron sputtering technique, these coatings are flexible and will not crack or delaminate. The coating both releases controlled silver ions in fluids and prevents bacterial colonization on the surface of the device itself.

Ion Implantation

Radioactive Coatings

PTFE Coatings

A significant advancement over other methods of surface treatment, ion implantation tailors surface characteristics such as hardness, lubricity, wettability, and resistance to wear and corrosion without adversely affecting the material's bulk properties. This is a distinct advantage in treating finished orthopedic components and medical devices, where precise tolerances must be maintained.

Ion implantation buries pure radioisotopes beneath the surface of a substrate, reducing the possibility of active isotopes leaching into the body. Various materials can be treated, and mechanical properties are unchanged. Our principal has developed a safe and effective process for implanting a variety of beta, gamma, and x-ray emitting radioisotopes. Medical devices implanted with radioisotopes can deliver a high dose of radiation directly to the site while still having a minimal effect on the whole body.

PTFE coatings are a popular choice to improve lubricity on wire mandrels for better release, as well as on needles and probes to improve fluidics. We offer these coatings on all types of metal products. Recent developments include a dry-release PTFE coating which has significantly improved lubricity without flaking over time.

Parylene Coatings

Parylene can be the optimal choice for improved lubricity when applied to wire, tubing and other metal substrates. This coating is ideal on silicone rubber and other elastomers, transforming the “sticky” surface into a smooth, even finish.
