Based on the results of the device history record (dhr) review, there is no indication that the device, labeling or packaging failed to meet its specifications when released.During visual inspection the catheter was returned with a non-stryker device.The catheter shaft was seen to be broken at 16 cm from the catheter tip.The catheter shaft was seen to be stretched/damaged.The inner coil wind was seen to be exposed through the break in the shaft.The catheter shaft was seen to be kinked 7, 9, and 18 cm from the tip and 12 cm from the catheter hub.The catheter tip was seen to be flat/crushed.The hub was intact.Functional inspection was not required, as the break was confirmed during analysis.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.The reported event ¿catheter shaft broken/fractured during use¿ was confirmed during analysis.The device failed to meet specifications when received for complaint investigation based on the analyzed anomalies noted to the device.The device was returned for analysis and the subject catheter was returned with a non-stryker device, the catheter shaft was seen to broken, the catheter shaft was seen to be stretched/damaged.The inner coil wind was exposed through the break in the shaft.The catheter shaft was seen to be kinked/bent.The catheter tip was seen to be flat/crushed.The hub was intact.Therefore the reported event can be confirmed.The device was sent for scanning electron microscope (sem) imaging for further evaluation.Sem images show evidence of bending and tensile stresses acting on the sample as seen by the presence of ovalization and folds on both fracture surfaces, and circumferential tearing on the outer surface of the distal end of the fractured sample.The reported event ¿catheter shaft broken/fractured during use¿ as well as the analyzed events: ¿catheter shaft kinked/bent¿ , ¿catheter shaft broken/fractured during use¿, ¿catheter shaft stretched¿, ¿catheter tip flat/crushed¿ 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.
