Coating Durability with Particle Analysis
To ensure stents or stent grafts do not pose an embolic risk over the lifetime of the implant, we perform simultaneous pulsatile durability and coating durability testing. In-line particle sensors provide a time-course of particle data throughout test duration. Membrane filters are utilized to collect any particulates generated. Shed particles are sized, counted, and then captured for subsequent analysis via SEM/EDX and/or FTIR, providing an assessment of integrity and efficacy of coated implants.
