One 120602f catheter was received for evaluation without any attached components.There was blood visible on balloon and windings.The reported issue of the catheter being swollen was confirmed.The proximal windings appeared thicker than known good lab sample.Furthermore, the proximal side of proximal windings was discolored.The catheter tube was bent at distal side of the hub.There was no other visible damage or abnormality observed from windings, balloon, and catheter body.The balloon inflated with 0.2 cc air as recommended in the ifu.The balloon inflated clear and concentric and did not leak.The catheter was sent for outer diameter (od) measurement.The outer diameter at the brown location was measured to be 0.0445" which was within specification.A review of the manufacturing records indicated that the product met specifications upon release.An unknown material detached during evaluation and was sent to chemistry for further analysis.The sample spectrum is consistent with that of zein (protein based material).Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.
