DuraPulse Stent/Graft Test (SGT) Instrument for Improved Performance and Reliability

The NEW DuraPulse™ Stent/Graft test (SGT) instrument is designed to extend the performance and reliability that was provided by the proven ElectroForce SGTs for the past two decades.

The instrument continues to use proprietary high-bandwidth, low-distortion ElectroForce actuator technology to offer quality performance, and incorporates a modular manifold design to allow users to easily change out manifold and tube sets in order to optimize sample throughput for several stented device sizes.

An improved software user interface is easier to use and includes outer diameter (OD) and inner diameter (ID) radial strain calculations, simplified data acquisition, and enhanced strain control modes.

Key Features

The main features of the DuraPulse™ Stent/Graft test (SGT) instrument are as follows:

  • Single test instrument can be enhanced for device geometry and sample number with interchangeable manifold sets – 12, 8, 6, and 4 (bifurcated) mock vessel options
  • Attain maximum frequency and strain combinations with closed-loop, symmetric dual-sided pulse
  • Can handle a wide range of device diameters ranging from 2 mm to 50 mm
  • Choose from 3 ID/OD strain calculation modes including zero strain or zero stress conditions (as stipulated by ISO 25539-2)
  • System operation state can be clearly identified with system status indicator (SSI) lights
  • Easily measures tube strain across all tubes with 360° manifold rotation and optical micrometer positioning slide, and a tube scanning operation that holds command levels and enables the laser to be repositioned while testing
  • Automate test pressure control with optional pressure control accessory (PCA)
  • Meets or exceeds international testing standards such as ASTM F2477 and ISO 25539-2
