One used 8 fr peripheral destination device was received for product evaluation.The device was decontaminated.No dilator was received with the returned destination sheath.After decontamination, the device was subjected to visual analysis.Dried remnants of body fluids were found along the body of the sheath, which is expected on used devices.There were no other noted anomalies found with the device.The device was then subjected to functional leak testing.The 3 way stop cock was moved into the off position and a 18 fr balloon was connected to the distal tip of the destination device.The air hose was then connected to the latex balloon and the air pressure was increased to 4.3 psi.The configuration was then submerged under tap water for 10 seconds and observed for any leaks.No bubbles were observed.An ik 8 fr dilator was inserted into the valve and no leaks were observed when the destination was submerged again.The dilator was then removed and the device was again inspected for leaks; none were found.After this leak test, the valve from the proximal hub of the destination sheath was dissected and observed under microscopy.There were no noted anomalies on either side of the valve.When the slits on the valve were observed no anomalies were noted other than the presence of dried remnants of what were once body fluids.A review of the device history record of the product code/lot number combination was conducted with no relevant findings.A search of the complaint file did not find any other report with the involved product code/lot number combination.There is no evidence that this event was related to a device defect or malfunction.Based on the results of the investigation, the cause of the event is unable to be determined.No anomalies other than the presence of dried body fluids were found on the device.These remnants are consistent with usage of the device, and did not affect the functionality of the device during testing.There was no failure of the device found.The ifu does speak to withdrawal in the dilator from the sheath slowly as rapid withdrawal may result in the incomplete closing of the valve resulting in blood flow through the valve.User error may have caused an incomplete seal of the valve, but testing was not able to replicate this.Additionally, the use of two wires side by side likely did not allow the valve to form a complete seal.All available information has been placed on file in quality assurance at the manufacturing facility for appropriate tracking, trending and follow-up.
