Information regarding suspect medical device.Common device name: not available.Regulation name: hemostatic device for intraluminal gastrointestinal use.Information regarding pma/510k: den170015.Investigation evaluation: our laboratory evaluation of the product said to be involved confirmed the report.All components were included in the return.One of the catheters provided with the return appears clogged with clumps of darkened powder.The other catheter appears to have been separated into two pieces.The device was returned with the on/off switch in the "on" position.The red activation knob was engaged in the handle indicating activation of the carbon dioxide (co2) cartridge.Powder was present on the exterior of the returned device and catheters.When tested as returned, the device sprayed with weak flow.The co2 cartridge discharged upon deactivation of the device.The lance position was measured and found to be positioned correctly.A visual examination of the o-ring and lance inside the handle showed both components to be positioned correctly inside the handle and the lance to be beveled.The inspection of the co2 cartridge and regulator (lance and o-ring) confirm the device was of the current design.When retested with a new co2 cartridge, the device sprayed as intended.When tested with the returned catheter containing powder, the device did not spray due to clogs within the catheter.The destroyed catheter could not be tested.The device history record for the lot number said to be involved was reviewed.A discrepancy or anomaly was not observed with the product that was released for distribution.Investigation conclusion: the report of unable to spray was confirmed.The catheter is clogged with hemospray powder.A definitive cause for the occluded catheter could not be determined.Catheter occlusion can be related to the handling of the device during the procedure.To assist the user, the instructions for use (ifu) state the following, "note: do not test device prior to insertion into endoscope accessory channel as this may increase risk of catheter occlusion.Precaution: to avoid catheter occlusion, do not place catheter directly in contact with blood and/or mucosa, including any pooled blood and do not aspirate blood while catheter is in accessory channel.Note: if catheter becomes occluded, turn red valve to closed position, remove catheter from endoscope and replace with extra catheter provided in package." prior to distribution, all hemospray endoscopic hemostats are subjected to a visual inspection to ensure device integrity.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: corrective action is not warranted at this time based on the quality engineering risk assessment.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
