High precision mock vessels made to exacting standards
Dynatek Labs: The Performance Leader for Mock Vessels
With a history of nearly 30 years of research and innovation behind us, Dynatek Labs produces the
most precise mock silicone vessels in the world. Dynatek pioneered the fabrication of mock vessels for
use in testing stents, stent grafts and some kinds of heart valves. Honed over decades, accuracy and
precision are the hallmarks of our proprietary mock vessel fabrication process, and today we are the
first choice for mock vessels by virtually every stent manufacturing company in the world.
What’s in a mandrel?
A mandrel is usually a stainless steel or aluminum rod accurately
shaped to the customer’s vessel specifications and used as a mold
for fabricating the mock vessel. A mock vessel can meet the required
specifications only if the mandrel from which it is made captures
the specifications accurately. Dynatek’s mandrels are machined and
finished to extremely close tolerances so that mock vessels from every
mandrel meet the requirements exactly.
Is it an art?
Yes, it is. Silicone is a tricky material to work with. Dynatek has nearly
three decades of research experience working with silicone and we
know, for example, exactly how much shrinkage to expect when the
mock vessel is removed from its mandrel. It is this kind of knowledge
that makes Dynatek’s mock vessels the most accurate and consistently
precise in the world.
Or is it science?
Yes, it is. The photo on the left is a close-up of a T-bifurcated mandrel.
In fact, it is a CNC-machined two-piece mandrel with the joint made
to such close tolerances that the seam is invisible to the naked eye.
Advantage? A bifurcated mock vessel with an ultra-smooth, bubblefree interior and naturally curved surfaces near the joint, just like a real
vessel in vivo.

The most anatomically accurate mock vessels you can buy
Simple to complex – we can do them all
From straight mock vessels to bifurcations to aortic arches and
complicated aneurysm models, our mock vessel division can
fabricate a wide range of vascular mock vessel anatomies. Our
standard compliance range is 5-7%, but we routinely make mock
vessels to other compliances.
Certified Compliant –Always
Dynatek measures the compliance and ID of mock vessels as part
of our QA process on our proprietary Dynamic Compliance Tester
(DCT) to ensure that they are consistent with the guidelines of ISO
7198. All mock vessels shipped to customers include a certification
of vessel properties indicating the % radial compliance at a specific
pressure, frequency and temperature.
More about Dynatek’s Silicone Mock Vessels
Dynatek’s silicone mock vessels are clear for optical clarity, ideal for testing stents, demonstrations or
training with complex interventional devices. We routinely fabricate mock vessels from 1.5mm ID to 52mm
ID, up to 30cm in length. Other custom lengths are available. Mock arteries can be specified by inner
diameter (ID), wall thickness or compliance. While our standard compliance is 5-7%, other compliances are
available upon request.
Custom Mock Vessels
Dynatek can fabricate mock vessels based upon your specifications:
•Shape
•Compliance
•Length
•Wallthickness
•Internalorexternaldiameter
No one has been making mock silicone vessels longer than Dynatek!
