Comparing Lubricious Coatings

Posted by Sean Horn on Fri, Dec 23, 2016 @ 07:47 AM

Selection of the material used to coat a medical device is very influenced by the operational environment it will encounter when implanted in the body.  Pertinent operational/performance factors typically include:

Parylene Protects Stents

Posted by Sean Horn on Fri, Dec 16, 2016 @ 07:48 AM

Biocompatible parylene conformal coatings provide superior protection for medical stents.  They represent an enabling technology consistently applied to medical devices of all types for 35 years, to diminish problems stemming from surface microporosity and consequent biofluid corrosion after implant.  Providing a reliable barrier to chemicals and moisture, parylene’s static and dynamic coefficients of friction are comparable to those of Teflon.

Parylene Coating Nitinol

Posted by Sean Horn on Fri, Dec 09, 2016 @ 07:24 AM

A metal alloy of nickel (Ni) and titanium (Ti), nitinol (NiTi) exhibits the properties of shape memory and superelasticity, which make it very useful for adaptation to conformal coatings.  However, like parylene, nitinol is often difficult and expensive to produce; the extreme reactivity of the alloy’s titanium component requires exceptionally tight compositional control during combination and manufacture.

Improving Patient Outcomes with Parylene-Coated Stents

Posted by Sean Horn on Wed, Sep 04, 2013 @ 07:04 AM

Coronary stents are tubular medical implants that serve as a scaffold to open clogged or narrowed arteries in an effort to increase blood flow and reduce the potential for adverse cardiac events such as heart attacks. And providing critical support to these support structures is parylene conformal coating.

Three Common Medical Applications for Parylene

Posted by Sean Horn on Tue, Jul 30, 2013 @ 09:32 AM

Parylene conformal coating boasts a bevy of benefits and properties that make it an appealing choice for a variety of medical device applications. Chief among parylene’s advantages for medical applications, however, is that it meets USP Class VI and ISO 10993 biocompatibility requirements—a characteristic that is essential for many critical medical products and that other types of conformal coating sometimes lack.

Parylene for use in Bio-Medical implantable devices

Posted by Sean Horn on Tue, Jun 12, 2012 @ 10:52 AM

Whenever implantable devices come into contact with the human body, long term protection against body fluids, enzymes, proteins, and lipids is vital.  Bio-medical surfaces typically require coating to protect from moisture, chemicals, and other potentially harmful substances.

 A downfall for wet chemistry, liquid coatings such as silicones, acrylics, epoxy, or urethanes is that they do not meet bio-compatibility requirements and cannot be applied with precise control.  On the contrary, parylene does not out-gas and is very effective against the passage of contaminants from both the body to substrate or substrate to body.
