Five Coated Stent Samples
Modular design keeps pace with your stent testing needs
CDT-5: The affordable durability tester for coated stents
The modular design of the patented1 CDT-5 Coating Durability Tester from Dynatek Labs, Inc. offers
durability testing and real-time particle counts from coated and bare metal stents in a compact footprint.
The CDT-5 is an affordable durability tester for up to five stent samples in straight, curved or bifurcated
mock vessels, with the capability to count particles being shed by these stents in real time. The CDT5’s linear motor produces an adjustable bellows compression which allows for stent loading conditions
from physiological to accelerated testing rates of up to 150Hz. Samples can be tested at precisely
controlled test parameters, and samples are easily accessed at all times for visual inspection or highspeed photography. Ideally suited for screening sample candidates in early stage stent research, the
CDT-5 offers unmatched flexibility. By allowing you to upgrade with an optional laser micrometer and
optional particle-capturing filters, the CDT-5 offers you the same technology as the workhorse CDT-20,
Dynatek’s 20-sample Coating Durability Tester, but with a significantly lower upfront investment.
The perfect low-to-medium throughput
platform
The CDT-5 features the technology of the CDT-20 while meeting the
need for a low-to-medium throughput. For young companies looking
to rapidly screen stent candidates, or established labs validating new
stent designs, the CDT-5 provides the most cost-effective solution.
Dynatek knows what’s important to you: affordability, flexibility and
cutting-edge science. With the CDT-5, you get them all.
Validate your stent design easily
The CDT-5 allows you to count particles in real time, as they are being
shed by your stents. The particle counter detects and logs particle
size and quantity, displaying the counts on screen. Real time particle
counting is a critical tool in your stent design toolbox, helping you
understand your stent’s particle-shedding behavior.
“…knowing that we could upgrade
the CDT-5 to meet our changing
needs was an important factor in our
decision to acquire it…”
Tremendous flexibility in a modular system
Dynatek’s CDT-5 was designed from the ground up to be a modular
system that can be upgraded to keep pace with your testing needs.
Up to five straight, curved or bifurcated tube configurations can be
tested under physiological to accelerated conditions produced by
compressible bellows driven by our proven linear motor.
Designed to support your lab’s current and future demands, the
CDT-5’s modular system allows for an upgrade with an optional laser
micrometer for accurate measurements of tube deflection. Looking
to characterize particles shed by your stent? The CDT-5 can also be
upgraded with an optional system that features an individual filter for
every tubing sample, allowing you to capture particles shed by each
stent in real time.

Giving you the technological muscle of larger labs – at a fraction of the cost!
Dedicated software gets you results faster
The CDT-5’s software package is easy to use right out of the box.
Intuitive menus with large, easy-to-read ‘dial type’ readouts on screen
allow you to conveniently set up, monitor and control instrument
status. Data from your tests are logged into TDMS files that can be
accessed by Excel, DIAdem and Matlab programs.
“…for a start-up like ours, the CDT-5 gave
us the technological muscle to quickly
screen our stent candidates and zero in
on those designs that had the greatest
potential, at a price that we could afford…”

Cutting-edge science with convenient
operation
The CDT-5 offers a powerful solution to stent testing challenges, while
remaining an easy instrument to operate. Case in point: you can hotswap samples on the CDT-5 in minutes with the optional isolation valve
system and spike wrench. Dynatek believes that powerful technology
should be easy to leverage and the CDT-5 exemplifies this belief.
An optional laser micrometer on the CDT-5 monitors the realtime outer diameter of the selected mock vessel as it undergoes
deflection. However, we know seeing is believing, and for the
most accurate visualization of stent deflection, we recommend the
optional high-speed camera. Two user-chosen points on the stent
are mapped throughout each cycle resulting in a very accurate
determination of stent deflection. With this tester, you will be
compliant with the requirements of upcoming regulations that
mandate observation of actual stent deflection. Only the CDT5 and its sibling the CDT-20 Coating Durability Testers offer the
optional high-speed camera upgrade.
Unmatched support provides peace of
mind
The technology, quality and reliability of our instruments have made
Dynatek the undisputed world leader in durability testing. When you
invest in the CDT-5, our world-class support is included, from training
your staff to ensuring maximum instrument uptime.
