Peripheral Stent Testing

Multi-mode testing of stents for peripheral arteries

Peripheral arteries have greater bending, twisting, and stretching motions than coronary arteries, so stents placed in peripheral arteries will undergo greater stresses and strains. Medical device companies, in conjunction with regulatory agencies, are testing stents under those combined loading conditions.

Bose has developed a multiaxial peripheral stent (MAPS) test instrument for stent applications in peripheral arteries. The ElectroForce® 9400 system is a programmable instrument that simulates the complex loading that stents experience in the peripheral arteries. These include the renal arteries, the carotid arteries, and the femoral-popliteal arteries.

Multiaxial performance is required to duplicate in vivo conditions

Capable of simulating the multiple axes of displacements to replicate in vivo conditions, the Bose® test system combines dynamic bending, rotation, extension/compression, and radial distention on multiple stents under controlled conditions. The instrument is capable of testing an accelerated 10 year simulated life, or performing fatigue to fracture studies.
