The Affinity Fusion Oxygenator with Integrated Arterial Filter and Carmeda Bioactive Surface is a single-use, microporous, hollow-fiber, gas-exchange device with plasma resistant fiber and integrated heat exchanger and arterial filter. The oxygenator is bonded on its primary blood contacting surfaces with a non-leaching biocompatible surface to reduce platelet activation and adhesion and preserve platelet function. The device is non-toxic, nonpyrogenic, and supplied sterile in individual packaging.

Medtronic initiated an Urgent Medical Device Recall for 66 distributed Affinity FusionTM Oxygenation Systems with Carmeda Bioactive Surface due to damaged heat exchangers. Product affected by this issue is limited to model CB841 sold stand alone or incorporated in Total Systems TS1614R1 and TS1595R7.
