(b)(4).Quality assurance product analysis received and examined the returned fetch 2 thrombectomy set.Visual examination confirmed that the catheter was kinked and cracked in various places throughout the catheter length.Functional testing determined that the device had a restricted vacuum as a result of the observed kinks and cracking in the catheter.Product analysis determined that the cracked catheter shaft occurred as a result of the energy that was applied, either all at once or repeatedly over time, to overcome the resistance that was met when attempting to advance the catheter through the sheath.
