It was reported that the sheath introducer of the optease filter got kinked.Therefore the device was replaced with a new 7f non cordis product and the procedure was completed successfully.There was no reported patient injury.This was a filter embolization case and an approach was made from the femoral vein.The target lesion was the inferior vena cava.The patient¿s vessel level of tortuosity and calcification are unknown.The rate of stenosis is unknown.The products were prepped according to the instruction for use (ifu).There was no difficulty noted during prep.There were not any damages noted to the device packaging.The product was clinically used and will be returned for analysis.A non-sterile optease retrievable filter was received inserted through the sheath introducer cannula along with the storage tube and the obturator.Per visual analysis, the catheter sheath introducer was received separated at 35.5cm from cannula hub (the distal section was not received for analysis).No anomalies or damages were found on the received obturator, the storage tube or on the filter.The cannula was inspected under microscope and the characteristics observed suggested cutting conditions.The received cannula was sent to sem analysis to confirm the cut characteristics observed on the received cannula.Sem analysis concluded that the separated section of the cannula showed evidence of elongations and partial cutting conditions, the pattern observed on the transversal section suggests that a sharp object induced the separation observed.No other anomalies were found during sem analysis.A device history record (dhr) review of lot 17594357 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 ¿catheter sheath introducer (csi) - kinked/bent¿ was not confirmed since no kinked conditions were found on the received unit.Instead of a kinked condition, a cut /separated condition was found on the received cannula.The cause of the ¿cannula (csi/filters) ¿separated¿ could not be conclusively determined during the analysis.The pattern observed on the transversal section suggests that a sharp object induced the separation observed.Handling or procedural process may have contributed to the separated condition found.The instructions for use cautions users to inspect for anomalies in the product, or other signs of damage prior to and during use.Any product with damage is not to be used.Neither the dhr review nor the product analysis suggests that the reported failure could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken at this time.
