Stent Testing

Dynatek’s patented* Coating Durability Tester utilizes a Hyper Drive linear motor to produce an adjustable bellows compression which allows for physiologically relevant stent loading conditions for up to 20 test samples from physiological to accelerated testing rates of up to 150Hz.

Dynatek’s laser particle detection system allows accurate real-time counting, sizing, and data logging of shed particles from each drug-eluting stent during testing, giving a time course of shed particulates from each sample.

The large number of samples greatly benefits manufacturing QA when ongoing testing of approved stents is required. 


Stent Particle Testing
