D4 expiration date - added.D9 product available to stryker- updated.D9 returned to manufacturer on- updated.H4 manufacturing date ¿ added.H3 device evaluated by mfg ¿updated.H3 summary attached - updated.Due to the automated manufacturing execution system (mes) system there are controls in the manufacturing process to ensure the product met specifications upon release.During visual inspection, the catheter shaft was seen to be flat/crushed 15cm from the catheter tip.There was an unknown material stuck to the catheter and appeared to be stuck under the catheter winds, the material was removed from the catheter.Although flattened, the catheter was not broken when the material was removed.The catheter was flushed and a patency mandrel was advanced but once the mandrel hit the flat area of the catheter, resistance was met and it was difficult to advance further.While removing the mandrel from the catheter the catheter shaft was damaged due to the resistance.As this shaft damage was caused during analysis it will no be assigned an as reported defect.The reported event is covered in the device direction for use (dfu).As well, the risk of the reported event is documented in the risk documentation and there are current controls to mitigate the risk of the as reported event.The product was returned.The reported catheter shaft broken/fractured during use was not confirmed during analysis, no breaks were found on the catheter shaft.The device failed to meet specifications when received for complaint investigation based on the analyzed anomalies noted to the device.It is likely that the substance extracted from the catheter coils is likely to be the inner lining of the outer catheter.It is believed that flattening the subject catheter device caused an increase in its outer diameter, leading to resistance while advancing it.It is also believed that the inner lining of the outer catheter got entangled within the subject catheter devices' coils.The as analyzed events of catheter shaft flat/crushed and catheter shaft friction will be assigned procedural factors as this complaint appears to be associated with a product that met stryker design and manufacturing specifications and was used in accordance with the dfu, but performance was limited due to procedural factors during use.An assignable cause of not confirmed will be assigned to the as reported event of catheter shaft broken/fractured during use as the issue included a returned product review (visual, physical, and/or performance testing) which showed no evidence of either the alleged issue(s) or any defect which could have contributed to the event.The manufacturer has reviewed all information and determined this event no longer meets the requirement of the reportable event for the device in question.
