Abstract
Apparatuses and methods for determining particle shed rates of implantable or inter-dwelling devices are disclosed. Durability test apparatuses with integrated particle counters produce time-dependent particle shed rate profiles. The apparatuses are designed to accommodate pulsatile flow, resembling a heartbeat at the implantable device. In an embodiment, the pulsatile flow is converted to a steady flow before fluid enters the integrated particle counter.
