(b)(4).It was initially reported by the customer that particulate matter was found in the outer pouch which was determined to be not reportable.Baxter initial medical assessment: sterile product is not bacteriologically contaminated.The particulate matter is not in contact with the device and cannot be introduced in the vascular system.After consideration for potential harms and worst-case scenarios, no adverse health consequence is reasonably expected to result from this issue.After further investigation, particulate matter was found in the inner pouch.The case was re-assessed by the medical director.Baxter's follow-up medical assessment.Particulates found either on or potentially inside devices that are designed to be utilized inside blood vessels have much greater consequences for the surgical patient.As this device is intended to be used inside of blood vessels, particulate matter on or potentially inside this device has a potential to introduce the particulate directly into the vascular system.In a worst-case scenario, this may lead to a compromise in blood flow through that vessel causing thrombosis or embolism.After consideration for potential harms and worst-case scenarios, an adverse health consequence is reasonably expected to result from this issue.Baxter synovis completed the investigation.Sample was available for evaluation.A single purple fiber (approx.2.5mm long) was found in the inner pouch and identified to be cotton.The complaint was confirmed.Batch record review was performed and all release products met specifications and no manufacturing defect was found.(b)(4) was initiated to further investigate the issue.Per synovis, source of fiber cannot be determined at this time.This case will be kept on file for trending purposes.
