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.
High precision mock vessels made to exacting standards
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, bubble-
free interior and naturally curved surfaces near the joint, just like a real
vessel in vivo.
