Type of Reportable Event	Malfunction
Event or Problem Description
It was reported that the subject guidewire was used for an interventional embolization procedure for a right mca (middle cerebral artery) m2 segment.When attempting to super selectively advance the subject guidewire device in combination with the microcatheter to the upper trunk of the m2 segment, the subject guidewire device became unresponsive to torque control.The subject guidewire device was withdrawn from the patient¿s body and observed that the distal end of the subject guidewire exhibited signs of fracture and stretching.The procedure was completed successfully with another device without any clinical consequences to the patient.
Additional Manufacturer Narrative
D4 expiration date ¿ added.D4 gtin- added.H4 manufacturing date ¿ added.Due to the automated manufacturing execution system (mes) system there are controls in the manufacturing process to ensure the product met specifications upon release.The subject device was not available; therefore, a visual inspection as well as a functional evaluation could not be performed.The reported events could not be confirmed and it cannot be confirmed that the device met specification as the device was not returned.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.It was reported that when attempting to superselectively advance the guidewire in combination with the microcatheter to the upper trunk of the m2 segment, the guidewire became unresponsive to torque control.The physician withdrew the guidewire from the body and observed that the distal end of the guidewire exhibited signs of fracture and stretching.Additional information received indicates that the patients anatomy was severely tortuous and the guidewire was torqued and 4 times.The device was not returned for analysis, however based on the information received, it was stated that the patients anatomy was severely tortuous.It is known that guidewire fractures may occur if manipulating through tortuous anatomy due to additional stresses that the anatomy can place on the guidewire during manipulation within the anatomy or within the devices being advanced.A guidewire becoming unresponsive to torque control is an infication of a fracture to the guidewire.It is probable that the guidewire was then stretched during the removal of the device.An assignable cause of procedural factors will be assigned to the reported 'guidewire torque problem', 'guidewire distal tip stretched' and 'guidewire distal tip broken/fractured during use', 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.
