Date of Event	02/26/2020
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
We have received the complaint device for evaluation and we have confirmed the reported incident.We observed the proximal ligature has slipped above the inflation hole which likely prevented the balloon from deflating during use.We also observed the catheter lumen to be stretched at 10-20 cm mark which suggest excessive force might have been used during the procedure to remove the thrombus.During our follow-up investigation with the complainant, we learned that the surgeon had tested the catheter before use and he found it to be operational.Surgeon had made multiple passes to remove the clot from the patient's vessel before encountering the deflation issue with the balloon.He was able to remove the undeflated balloon from the patient's vessel without requiring any surgical intervention.He further stated that the balloon was operated in a patient with stenotic vessel.There were no fragments left over inside the patient's vessel when he removed the catheter from the patient's vessel.Surgeon felt resistance when removing the thrombus and he clearly stated that the catheter may have been used with excessive force.Our review of the lot history records for this lot did not find any discrepancies either in the manufacturing or packaging process that could be related to this incident.After receiving this complaint, we have also tested a sample of catheters from this lot number.The tested catheters performed within its specification when they were pull tested to their validated force.Based on the information provided and our device evaluation, the device had performed properly during initial use.The issue might have occurred when removing the residual adherent thrombus from the patient's vessel.It does not appear to be an assembly issue since the user was able to make multiple passes successfully with this device and a sample of units from this lot number that we pull tested also met specification.It is possible that some anatomical (calcification or stenosis in the lesion area) or procedural factors (use of excessive force to remove the thrombus) may have contributed to the balloon failure since we observed necking on the catheter shaft which suggest that the device was pulled above its pull force specification.The arterial embolectomy catheter is not recommended for the removal of fibrous, adherent or calcified material (eg.Chronic clot, atherosclerotic plaque).This catheter is not designed to withstand the additional pull force needed to remove these materials there was no injury to the patient as the result of this incident.Please note that we have also submitted manufacturer incident report# 1220948-2020-00038 related to another similar incident that occurred during the same case prior to the aforementioned incident.
