The electronic device history record (edhr) review confirms that the device met all material, assembly and performance specifications.The reported event is covered in the device directions 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.During analysis, the coil was found to be broken/fractured.The damage noted to the main coil is indicative of the as reported defect.It is likely that the main coil was damaged during use which led to friction in the introducer sheath and catheter as reported initially.Based on the investigation, these defects appear 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 or anatomical factors during use.Therefore, a probable cause of procedural factors was assigned to the as reported event coil in catheter friction and the as analyzed events coil broken/fractured and coil introducer sheath friction.It can be presumed that the delivery wire was damaged during the procedure as force may have been applied when the friction was felt.Because this defect appears to be associated with handling of the product or portion of the product during the procedure/upon removal of the product from the packaging/preparation of the product prior to use, a probable cause of handling damage was assigned to the as analyzed events coil delivery wire kinked bent and coil proximal contact wire broken/fractured.
