Our product evaluation laboratory received one hemostasis valve introducer on its original opened tray (lot 61532849) with one dilator, one guidewire, two 5cc syringes, one contamination shield, one cap, one sharp receptacle, and four gauze pads.Examination of the hemostasis-type introducer found the wiper gasket to be missing from the valve housing.Resistance was felt when inserting and removing the dilator from the introducer.Further examination found that the wiper gasket was stuck in the sheath body at approximately 9cm from the distal tip.The dilator was hard to insert when the wiper gasket occluded the lumen.The wiper gasket was found bent and torn when it was removed from the sheath.When the wiper gasket was removed, the dilator was able to pass freely through the entire length of the introducer without issues.The duckbill valve was undamaged.A device history record review was completed and documented that the device met all specifications upon distribution.The customer report of "difficulty to place" was confirmed on evaluation.An engineering evaluation has been initiated to assess for any manufacturing-related processes which could be correlated to the complaint.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to perform the procedure, to consider the potential benefits in relation to the possible complications.In this case, the wiper gasket was missing from the valve housing of the introducer and was inside the introducer sheath, which has the potential to embolize into the patient.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 part of this monthly review.
