It was reported during procedure, the resistance was encountered when introducing the subject device (streamline) into the body of catalyst catheter.The distal radiopaque marker (ro) came off of the subject device outer body catheter portion of the stent delivery system.Since the ro marker came off of the system, the stent was deployed in error where it was not intended to be placed.The physician decided to use different stent and coils to embolize the aneurysm.The ro marker was removed from the patient via mechanical aspiration.The procedure was completed with no clinical consequence to the patient.Post procedure, the physician reviewed the case in detail and thinks that the ro marker from the subject device catheter was either lodged within catalyst catheter or was floating around in the rhv (rotating hemostatic valve).Only until the physician did an injection through the catalyst catheter then see the ro marker shoot out of catalyst catheter and become lodged on the stent strut that was just deployed moments prior to the injection.

Due to the automated mes system there are controls in the manufacturing process to ensure the product met specifications upon release.Due to the automated mes system there are controls in the manufacturing process to ensure the product met specifications upon release.Visual inspection revealed that the radio opaque (ro) marker was detached from the damaged distal tip of the delivery catheter and the stabilizer was kinked at 47cm and 74cm from the proximal end.The subject flow diverter stent was not returned.Following the functional test, the stabilizer was able to move freely within the delivery catheter.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.As per the available information, when the md introduced the streamline system into the cat5 he noted that he did catch the tip of the catheter in the hub, and then felt resistance when introducing into the body of cat5.Resistance was felt approximately 2-3 inches in from the hub.The device was returned, and it was confirmed that the ro marker had detached, also the stent stabilizer was kinked.It is probable that the device was damaged during insertion into and advancement through the proximal end of the cat5 catheter causing the ro marker to detach.An assignable cause of procedural factors will be assigned to the reported event and to the analysed ¿ ro marker(s) detached/separated/not visible under fluoroscopy¿ and ¿ stent stabilizer kinked/ bent¿, as the issue is associated with a product that meets stryker design and manufacture specifications and was used in according with the dfu but due to procedural and/or anatomical factors during use, the product performance was limited.
