Dr. Josh Simon is the Group Product Manager for Coating Technologies at Biocoat, and an Adjunct Professor at the New Jersey Institute of Technology where he teaches courses on medical device development and orthopedic medical device basics. He comes to Biocoat from the orthopedics industry where he had held positions in Research and Marketing. He holds a BS in Chemical Engineering, MS and PhD degrees in Biomedical Engineering, and an MBA in General Business. Past research experience includes engineering cellular response to controlled bone scaffold architectures, electrical and ultrasonic stimulation of bone healing, hydrophilic coatings, and drug-eluting coatings. In his current position at Biocoat, he heads the Marketing and Product Development functions and shares his impressions via his blog at http://blog.biocoat.org.


Hydrophilic coatings have been employed in medical devices for lubricity and non-thrombogenicity since the 1980’s, and have successfully been sold on guidewires and catheters for the cardiovascular, neurovascular, urological, and other markets. Nevertheless, characterizing and choosing a hydrophilic coating has been an inexact science. When considering data on coating friction and durability, the test methods and parameters can have massive effects on coating performance, which may or may not be relevant engineering considerations depending on the application. This webinar gives examples of how testing parameters for a specific type of pinch test can alter performance.

This webinar will discuss: • Specific methods of pinch testing and how they can influence results • Data on how certain pinch test parameters affect coatings • Other possible methods for measuring lubricity and durability of surfaces
