Event Description
Medtronic received a report that the pipeline only opened in the distal segment, and then failed to open in the middle. It was noted the stent was positioned in a bend, less than 50% had been deployed, resheathing was performed more than twice, and no additional steps were taken in an attempt to open the pipeline. Upon removal, it was noticed the stent was severely constrained. A replacement stent was used to complete the procedure with no reported issues. It was indicated that all devices were prepared as per the instructions for use (ifu), and no patient symptoms or further complications were reported as a result of this event. The patient was undergoing surgery for treatment of a saccular, unruptured aneurysm of the left carotid artery with a max diameter of 9 mm and a 4 mm neck diameter. It was noted the patient's vessel tortuosity was moderate. Dual antiplatelet therapy (dapt) was adm inistered, and the platelet reactivity units (pru) level was 300.
