Other Cardiovascular Devices
Many new classes of devices do not have standards like more established technologies. We excel at breaking down a complex device and pathophysiology into a justifiably simplified bench top test. Each will have well defined:
- Operating conditions [eg. inlet pressure, outlet pressure, internal chamber pressure (if applicable), inflow, outflow, relevant mock heart chamber pressures, cardiac output, and systolic duration]
- Test fluid properties (Chemical composition, temperature, viscosity, density, pH)
- A priori defined acceptance criteria such as acceptable pressure drops, retrograde flow, etc.
Our test plans and reports are designed around approval bodies, thoroughly researched, and justified to ensure they are regulatory appropriate. Contact us today to discuss your cardiovascular testing needs.

Experimental Flow Field Assessment – Digital Particle Image Velocimetry (DPIV)
Using Digital Particle Image Velocimetry (DPIV), pulsatile flow conditions in the immediate vicinity of the device can be analyzed to determine the viability of cardiovascular devices meeting regulatory standards. Triggers for disease (such as shear stresses and regions of stagnation) can be quantified with a high degree of accuracy. Advanced methods, including proper orthogonal decomposition, also capture the implicit fluid mechanical phenomenon of interest.Learn more
Test specimens are exposed to X-Ray levels necessary for the imaging system and the product or material. Digital analysis method is used to produce the images in accordance with the equipment manufacturer’s instructions. Radiopacity of the device is determined by qualitatively comparing X-ray image(s) of a test sample and a user-defined standard with or without the use of a body mimic.Learn more
