Test Assesses Stent Coatings

Jan. 19, 2007 — The second generation Coating Durability Tester (CDT2) by Dynatek will be exhibited at the Medical Design & Manufacturing West Expo in Anaheim, CA, Feb. 13-15, 2007, Booth 2592.

Originally released in 2005, CDT is designed to evaluate the durability of coatings on drug-eluting and other coated stents — demand has since increased for the testers and testing services. Dynatek’s second-generation testers include additional capabilities to address a wider variety of devices and testing techniques.

The CDT2 allows for a larger range of sample lengths and diameters, as well as for complicated sample designs (bent, bifurcated, etc.), opening the door for testing of larger peripheral vascular stents, as well as complicated coronary and peripheral stents.

Dynatek says its new design also readily accommodates laser micrometer use for sample measurement, allows for vertical or horizontal testing, and provides internal loop heating for better temperature control. Deployment access ports are also available, and provide for direct stent deployment into the pre-mounted sample vessels, allowing the CDT2 to be used for both acute-phase and chronic-phase coating durability testing.
