It was reported that in the icu, a flushing test was performed prior to insertion of the catheter and no problem was confirmed at that time.The catheter was inserted into the patient, and after, the patient was moved to the icu.It was there that the md found a blood backward flow occurring at the extension line of proximal lumen.As a result, the catheter was removed and replaced with a new one.There was no reported delay, death, or complications to the patient as a result of this occurrence.

(b)(4).Device evaluation: it was reported that there that the m.D.Found a blood backward flow occurring at the extension line of proximal lumen this issue was not confirmed.One 7 fr x 20cm 2-lumen catheter was returned.The catheter body was cut off below the proximal skive - approximately 4 cm from the distal tip.Dried blood was observed in the proximal extension line.The catheter showed evidence of use but no defects or anomalies were observed during visual examination at 10x magnification.The catheter was leak tested.With the opposite end of each lumen occluded, water was injected into each extension line.Each lumen was pressurized to 45psi for 30 seconds.No leaks or cross-overs were observed.Since the catheter body was cut off below the proximal skive hole, the leak test is considered to be representative of the proximal lumen during use.A device history record review was performed and did not reveal any manufacturing related issues.No leaks were detected in either lumen of the catheter.No problem was found on the sample.No further action will be taken.
