(b)(4).One 2-lumen cvc catheter was returned for evaluation.The sample had evidence of use, the catheter box clamp was attached to the catheter body and stopcock extensions were attached to each of the catheter extension lines.Visual examination with the naked eye did not reveal any defects or anomalies.Microscopic examination of the juncture hub suture wings of the catheter revealed they did not appear to have damage/wear.Evidence of use was observed on the catheter box clamp insert as the suture holes were laterally pinched, indicating sutures had been applied.The catheter body outer diameter (od) was measured and was found to be within specification.The catheter clamp fastener diameter and the catheter clamp inner diameter (id) were also measured and were within specification.The clamp and the clamp fastener were reassembled.The largest pin gauge that would pass through the clamp assembly without resistance was 0.077".This indicates that the clamp would securely hold a catheter that has an od of 0.096".The box clamp was placed on the catheter and the catheter body was then tugged on either side.The catheter remained in place.A device history record (dhr) review was performed on the catheter and no relevant manufacturing issues were identified.The instruc tions-for-use (ifu) provided with this kit states that the catheter clamp and fastener can be used as a secondary securement site is needed in addition to the primary securement site, the catheter juncture hub.The ifu also states that indwelling catheters should be routinely inspected for desired flow rate, security of dressing, correct catheter position and for secure luer-lock connection.It was reported that the cvc catheter migrated out of the patient while in use.Customer reported that the primary suture site (juncture hub) was used; however, no obvious signs of use were observed on the juncture hub suture wings during investigation.The issue could not be confirmed through functional or dimensional testing of the returned sample.The catheter remained secure in the catheter clamp when it was tugged and the components met dimensional specifications.A dhr review did not reveal any manufacturing related issues.No problem was found on the sample.
