Manufacturer Narrative
|
The device history record review confirms that the device met all material, assembly and performance specifications.The subject device is not available; therefore, functional testing as well as physical analysis cannot be performed.While there are a number of potential causes for the reported issue, because review of available information failed to identify a definitive cause and the device was not returned for analysis, a cause of undeterminable has been assigned to this investigation.

Event Description
|
It was reported that during the procedure, the physician extracted the tip of the subject coil pusher wire and it was slightly kinked.This lead to further kinking during advancement of the subject coil in the micro catheter and incomplete detachment inside the patient anatomy.The physician removed the subject coil and replaced it successfully with a new device and continued the procedure without clinical consequences to the patient.

H4 manufacturing date ¿ added.H3 device evaluated by mfg ¿updated.H3 summary attached - updated.D4 expiration date - added.D10 product available to stryker ¿ updated.D10 returned to manufacturer on ¿updated.The device was returned within a dispenser coil in the introducer sheath.The lot number was confirmed with the packaging returned with the device.During visual inspection, the proximal contact wire was intact.The coil delivery wire was kinked/bent.The main coil was returned attached to the delivery wire.The distal tip was found to be intact.The main coil was severely stretched.The suture was damaged.Main coil length could not be measured due to the condition of the returned device.No other anomalies were noted.During functional inspection, coil friction in introducer sheath test - fail.The device was flushed and advanced in the introducer sheath, there was resistance felt.The reported defect of main coil prematurely detached/separated inside patient was not confirmed.The reported defect of coil delivery wire kinked/bent was confirmed during analysis.Due to the automated mes system there are controls in the manufacturing process to ensure the product met specifications upon release.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 main coil was returned attached to the delivery wire.As such, the as reported main coil prematurely detached/separated during use was not confirmed.The main coil was found to be severely stretched and the suture was damaged causing introducer sheath friction during analysis.Therefore, the as analyzed events will be assigned procedural factors as 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.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, a probable cause of handling damage will be assigned.The manufacturer has reviewed all information and determined this event no longer meets the requirement of the reportable event for the subject device.
