Event Description
|
Medtronic received a report that three pipelines failed to open distally and experienced resistance in the distal segment of the phenom 27 microcatheter.The patient was undergoing treatment for an unruptured, wide-necked, saccular aneurysm located in the right internal carotid artery.The max diameter was 7 mm, and the neck diameter was 4 mm.The landing zone was 4.53 mm distal and 4.78 mm proximal.The patient¿s vessel tortuosity was severe and was said to have a high riding posterior genu.The access vessel was the ica and was 4.78 mm in diameter.It was reported that the phenom 27 microcatheter was advance into the m1 with a degree of difficulty.The first pipeline (4.5 x 20) was attempted to be advance past the aneurysm.The physician experienced a great degree of resistance and eventually navigated into position and began to unsheathe the device.Approximately 50% of the device was unsheathed and the distal tines of the pipeline would not open and appeared to be frayed.The device was removed,and a second attempt was made with a 4.75 x 18 pipeline.The physician encountered resistance and once in position again attempted to deploy the device.The pipeline again opened in the center, but the distal segment remained closed.This device was removed, and a third attempt was made with a 4.75 x 16 pipeline.There was resistance while delivering, and when the device began to unsheathe the distal end remained closed.The physician decided to remove the device and discontinue treatment.The patient will be rescheduled for later date with a different device.The device had not been placed in a bend, and more than 50% had been deployed when it failed to open each time.Two or less resheathing attempts were made, and no additional steps were taken to open the device.The patient did not experience any injury or complications.The devices were prepared and flushed according to the instructions for use (ifu).Ancillary devices include a navien 058 guide catheter, stryker cat 5 guide catheter, and synchro 2 guidewire.
