Device evaluated by mfr: the complaint device was received for product analysis.Returned product consisted of the peripheral rotalink plus atherectomy device.A piece of material was included within a ziploc bag with notation identifying the material as the same as depicted in an attached photo.The advancer, drive shaft, and handshake connection were visually and microscopically examined.Inspection of the device found additional fm material on the coil resembling the material received within the ziploc bag.There were no further damages or irregularities identified to the device.In order to determine the nature of the foreign material, an ftir was used and found that the material most closely resembled ptfe [teflon] from within a guide catheter.Product analysis confirmed the reported event, as there was ptfe material identified on the coil during inspection.It is likely that the reported difficulty withdrawing the device was attributable to interference from the ptfe material.
