As reported, a 6f,10cm rain sheath did not want to insert all the way into the radial artery while using ultrasound guided access.When they tried to draw back blood, air and clot were observed in the sheath.The decision was made to abort that site and try more distal closer to the wrist.The physician noted evenly spaced ¿kinks¿ in sheath, and the physician asked for a new 6f rain sheath which went in and performed perfectly.There was no reported patient injury.The device was flushed prior to use.The vessel dilator was snapped into place at the hub.There were no patient specific anomalies noted at the insertion site.The device was prepped per the instructions for use (ifu).The csi was soaked and inserted half-way before experiencing insertion difficulties.The patient had not received adequate anticoagulation prior to inserting the sheath.The user was trained to the device.A non- sterile csi ¿6f,10cm sw radial" was received for evaluation.Only the catheter sheath introducer (csi) was returned for analysis.The cannula of the csi presented with a kinked condition located approximately 9.7 cm from the distal tip, and accordioned conditions located approximately 4, 4.5, 5, 6, 6.8, and 7.8 cm from the distal tip.No other outstanding details were observed during visual analysis.Inner diameter (id) and outer diameter (od) measurements were taken near the damages and were found within specification.Functional analysis was performed by filling a syringe with water and attaching it to the stopcock of the csi.Positive pressure was applied to observe for leakage and no leaks were observed.The unit was inspected with a vision system confirming the accordioned and kinked conditions.A product history record (phr) review of lot 18168529 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The complaint reported by the customer as ¿thrombosis in device¿ was not confirmed.This adverse event is not related to the product functionally and the existence of a clot cannot be confirmed by product analysis.The complaint reported by the customer as ¿catheter sheath introducer (csi) ~ leakage¿ was not confirmed.The returned unit did not present with any leaks.The complaint reported by the customer as ¿catheter sheath introducer (csi) ~ kinked/bent¿ was confirmed, a kinked condition was observed on the cannula of the returned unit.Additionally, an accordioned condition was observed on the cannula.Exact cause of these damages could not be conclusively determined during the analysis.Patient specific factors such as the patient¿s coagulation status may have contributed to the clot formation.Procedural factors such as inadequately flushing the device prior to use and failure to adequately hydrate the hydrophilic coating may have contributed to the insertion difficulties that likely preceded the noted damages.Users are trained to inspect for signs of damage prior to and during use.Any product with damage is to be used.Information for safety is provided in the products labeling with the intent to make the user aware of the risks.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿if resistance is felt upon insertion or withdrawal, investigate the cause before continuing.Possible complications include, but are not limited to: abrupt vessel closure, additional intervention, allergic reaction (device, contrast medium and medications), air embolism, infection, intimal tear, hematoma at puncture, hemorrhage, inflammation / infection / sepsis, ischemia, perforation of vessel wall, thrombus formation, peripheral nerve injury, pain, vascular complications (e.G.Intimal tear, dissection, pseudo aneurysm, perforation, rupture, spasm, occlusion).Inspect the system contents for any signs of damage; do not use if any damage is present.Soak the csi in sterile heparinized saline or similar isotonic solution to activate the hydrophilic coating.Prior to use, remove air from csi through the side port extensions by inverting and flushing with heparinized saline or suitable isotonic solution.Caution: failure to flush the device prior to use may result in air embolism.¿ based on the information available and the phr review, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
