Event Description
Medtronic received information that a ped2 pipeline stent failed to open in the distal section.The patient was being treated for an unruptured, amorphous aneurysm in the right vertebral artery.The distal landing zone was 5mm and the proximal landing zone was 5mm.Vessel tortuosity was moderate.Dual antiplatelet treatment was administered.  the distal portion of device was not fully open and apposed to the arterial wall of artery.The physician used a micro wire with a ¿j¿ shape on the end to run through the pipeline and open the distal end.As the device was being manipulated the proximal end was pushed into the aneurysm body and the micro wire and micro catheter were ¿flipped¿ out of the pipeline and access was lost.After several attempts the physician was unable to recannulate the device.Blood flow was still observed in the artery and the surgeon elected to leave the device in place and observe it as they considered further treatment options.The distal part of the pipeline was positioned in a bend.More than 50% of the pipeline had been deployed when it failed to open.No additional steps were taken.Full wall apposition was not achieved.Ballooning was not required.Proximal end of device was pushed into aneurysm, blood was still flowing into the vesselpost procedure. device remains implanted; patient may go to surgery for alternate aneurysm treatment.The pipeline was used for an indication that was off-label in the vertebral artery.The devices were prepared as according to the instructions for use (ifu).

Event Description
Additional information received reported the distal end of the device was around a bend and challenging to navigate to.Once in place, the distal end of the pipeline remained in place but would not fully open.After full deployment, the distal end was still not fully opened.The mid-section and proximal ends were fully opened and across the aneurysm.The physician used the micro-wire to attempt to open the distal end.During the manipulation with the micro-wire, the proximal end of the pipeline moved forward and into the aneurysm.The microcatheter and micro-wire came out of the device and the surgeon was unable to recannulate the pipeline.Bloodflow remained intact and the doctor elected to end the procedure and observe the patient while additional treatment options were considered.The pipeline did not jump and remained in place during deployment.Multiple pipelines were not being used, and the tip of the catheter was not under stress.The catheter tip was not moved during deployment, and the phenom 27 microcatheter performed as expected during delivery.The microcatheter came back as the pipeline was pushed forward during deployment.
