Additional Manufacturer Narrative
There are controls in the manufacturing process to ensure the product met specifications upon release.During visual and microscopic inspection, it was observed that the subject catheter shaft was seen to be flat/crushed at 14.5 cm from the hub and kinked/bent at 27.5 and 118 cm.The catheter hub and tip were intact and no fracture or perforation was noted.Functional testing was not carried out due to the damage noted to the subject catheter.The subject catheter was flushed without difficulties no leaks were noted.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 reported catheter shaft friction could not be duplicated during device analysis; however, the analysis results are consistent with the reported event.The reported catheter shaft broken/fractured during use and catheter shaft has hole/perforation were not confirmed during the analysis.The device failed to meet specifications when received for complaint investigation based on the analyzed anomalies noted to the device.The subject catheter shaft was seen to be flat/crushed and kinked/bent.No fracture or hole/perforation was noted on the catheter during analysis.The catheter tip and hub, both were found to be intact.The as reported code, 'catheter shaft friction' as well as the as analysed codes, 'catheter shaft kinked/bent' and 'catheter shat flat/crushed' will be assigned procedural factors.This complaint appears to be associated with a product that met 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' was assigned to the as reported codes 'catheter shaft broken/fractured during use' and 'catheter shaft has hole/perforation' 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.
