UST
SVP-24 Stent and Vascular Prosthesis Tester
and the New UST Universal Stent Tester
Introducing:
The World’s Most Versatile
Stent Testing Platform for
Stents and Grafts
from 2 to 50mm ID.
The revolutionary solution for all your radial fatigue-testing needs
SVP-24 and UST – Delivering next-generation productivity today
Hot on the heels of the SVP-24, Dynatek Labs is proud to introduce the most powerful stent and graft
durability testing platform in the world: the UST Universal Stent Tester. Until now, radial fatigue stent
tester designs were severely constrained: you had to invest in three to five separate test units if you
needed to test samples from 2 to 50mm ID. The upfront investment for a company testing samples in
the coronary to stent graft size ranges was prohibitive. Now, with a single UST Universal Stent Tester,
you can conveniently test any size of stent or stent graft on only one machine, just by swapping out an
optional manifold!
Design solution for unmatched versatility
Retaining many of the powerful features of the original SVP-24 Stent
and Vascular Prosthesis Tester, each UST platform consists of a Hyper
Drive and bellows module and a sample manifold module in which the
stent samples are mounted. Based on the size of your current stent test
samples, you can choose the optional sample manifold module sized
for your sample ID. Testing larger or smaller samples? No problem!
Choose from one of four interchangeable manifold modules that best
fits your needs, swap out the existing sample module and you’re ready
to test a different size.
Lowest cost of ownership
With the UST, you only have to invest in one test platform to test
stent and graft samples regardless of their internal diameters. The
UST’s powerful all-in-one platform gives you the productivity of four
radial durability testers at slightly more than the price of one unit. To
maximize your return and protect your investment, nothing beats the
UST.

One product platform – multiple
applications
For high sample capacity, the SVP-24 is unbeatable. For flexibility
in testing however, the UST offers unrivalled productivity with the
convenience that only a truly modular platform offers. Each dedicated
manifold is sized for an application-specific range of sample IDs, with
the XL manifold offering the widest range. Choose from any of the
following optional sample manifolds on the UST to suit your sample
requirements:
Straight
Platform Sample ID range Sample #
SVP-24 2-10mm up to 24
UST-M 11-16mm up to 16
UST-L 17-24mm up to 12
UST-VL 25-50mm up to 8
UST-XL 2-50mm 8 to 16

Innovative technology
delivers superior testing results
One motor or two?
Dynatek’s SVP and UST feature a single motor that drives fluid
with a pulsatile motion into the whole sample. This ensures that
the entire sample is undergoing the same test condition and the
pressurization is most like how the heart pressurizes the vasculature.
Since pulsatile conditions are uniform across the entire length of
the mock vessel that contains the sample, the SVP-24 and UST,
unlike dual-headed units, can test up to five stent samples in a mock
vessel, (depending on the length of the stent) offering significantly
increased capacity. With the SVP-24 and UST, cutting edge science
delivers uniform test conditions and exceptional performance.
The vertical configuration of the SVP-24 and UST permits
bidirectional rotation of the manifold, allowing the included laser
micrometer to take deflection readings of samples conveniently.
The Flow-Through Adapter allows test fluid to be pumped through
all samples in a closed loop, ensuring an even temperature
distribution within all mock vessels and also ensuring the removal
of shed particles, which is of particular importance during the
testing of bioabsorbable stents.
“…the UST lets me choose sample exibility
or high throughput when I need it.”
In competitive units featuring two motors, two wave fronts
rush inwards towards the middle of the sample where they
collide. The required test condition is only created in a
narrow center region, resulting in only the center of the
sample being adequately tested. This situation is worsened in longer samples, where the two extremities of the
sample are further away from the central ‘test region’ on
the sample.
Furthermore, dual-motor units can only test one stent per
mock vessel, since test conditions are obtained only in the
center of each mock vessel.
Designed for reliability and long life
With only one powerful, long-life Hyper Drive linear actuator, the
SVP and UST feature a minimal number of moving parts, about half
the number of moving parts in competitive testers featuring two
motors. Proprietary alloy bellows are designed to run for over a
billion cycles and the rugged manifold is fabricated from durable
Delrin.
Frelon Gold™-coated linear bearings on the linear actuator are
designed to absorb enormous loads, provide smooth motion and
reduce stress on the motor, and the custom motor shaft features a
Diamond-Like Coating (DLC) making it extremely hard and wearresistant. Result? The SVP-24 and UST will provide years of virtually
maintenance-free performance.
Boost productivity with optional
accessories
A wide range of optional add-ons have been tailor-made to meet
the needs of stent and graft testing protocols:

Maximum throughput or greatest versatility?
How do I choose the right tester for my device testing needs?
If you’re testing coronary, renal, SFA or carotid stents, and you are looking for maximum sample throughput, you may choose the SVP-24,
which would cover samples with IDs up to 10mm. For iliac stents, you may choose the SVP-24 or UST-M or -L, depending on the ID of
your stent. For AAA or TAA stent grafts, you may choose UST-VL for devices up to 50mm ID. Note that depending on the choice of UST
manifold, you will be able to test smaller or larger numbers of samples.
For greater versatility, you may choose the UST-XL. The UST-XL can test up to eight TAAs and AAAs with IDs up to 50mm. With the use
of optional sample adapters, you can test from 8 to 16 smaller stents from 2-24mm ID on UST-XL. For the best ROI, choose more than
one manifold when you invest in the UST.
