The distal tip of a precise pro rx 10mm x 40mm self-expanding stent delivery system was separated.The device broke off inside the artery after deployment of the stent.The angioguard and stent delivery system were removed together, and the filter basket was used to capture the broken piece of the stent delivery device.There was no reported patient injury.The device was returned for analysis.Per visual review, one non-sterile precise pro rx us carotid syst was received for analysis inside a plastic bag.No original packaging was returned.The valve of the unit was received opened.Per visual analysis, the stent of the unit was observed deployed but was not received along the unit.The wire lumen was observed separated from the distal tip.Distal tip was not received.Since the distal tip was not received, visual analysis couldn¿t determine if the correct amount of adhesive was applied through the entire section between the wire lumen and the tip.A kink was observed on the wire lumen near to the pod.No other anomalies were observed.Pull test of tip and process tip were reviewed and no issues were noted that could be related to the reported complaint.A product history record (phr) review of lot 17934634 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿catheter tip - separated - in patient¿ was confirmed since the distal tip was observed separated from the wire lumen.Nevertheless, the distal tip was not returned for its analysis.Since the distal tip was not received, visual analysis couldn¿t determine if the correct amount of adhesive was applied through the entire section between the wire lumen and the tip.After the physical evaluation of the unit, it was determined by the engineering team (pet) that the tip separation was a manufacturing related.As the physical evaluation of the unit couldn¿t conclusively determine if the correct amount of adhesive was applied through the entire section between the wire lumen and the tip.According to the instructions for use, which is not intended as a mitigation of risk, ¿extract the stent delivery system from the tray.Examine the device for any damage.Evaluate the distal end of the catheter to ensure that the stent is contained within the outer sheath.Do not use if the stent is partially deployed.Note: if resistance is met during delivery system introduction, the system should be withdrawn and another system should be used.Note: if any resistance is met during delivery system withdrawal, advance the outer sheath until the outer sheath marker contacts the catheter tip and withdraw the system as one unit.¿ the product analysis suggests that the event experienced by the customer could be related to the manufacturing process; therefore, a corrective/preventive action will be taken at this time.
