Manufacturer Narrative
Product analysis: as found condition: the devices were returned for analysis within a shipping box, within a tyvek bio-pouch, and within primary and secondary plastic bio-pouches. ¿ visual inspection/damage location details: the pipeline flex pusher distal hypotube was found stretched with the shrink tubing pulled back from the proximal bumper. The pusher¿s proximal bumper was found intact. The pusher¿s distal core wire was found broken. The phenom 27 catheter was examined. The phenom 27 catheter hub was found in good condition. However, the pipeline flex braid was found within the hub lumen. No bends or kinks were found with the phenom 27 catheter body. No damage was found with the phenom 27 distal marker/tip. The phenom 27 catheter body was dissected (cut) and the pipeline flex braid, ptfe sleeves, and tip coil were removed from within the hub. (pli-50) the pipeline flex braid ends were found open, but damaged (frayed). The pipeline flex ptfe sleeves and tip coil were found damaged. The pusher¿s distal core wire was found broken at the ptfe sleeves. Testing/analysis: the pipeline flex pusher distal core wire was sent out for sem (scanning electron micrographic) analysis. The wire failed via torsional overload. Conclusion: although no device malfunction was reported by the customer, the pipeline flex pusher distal core wire was found broken at the ptfe sleeves. The investigation determined that this event was similar to an event that had already been investigated, and another investigation is not necessary. Based on the formal investigation conducted, pusher separation can occur due to certain use conditions such as excessive force and patient vessel tortuosity. The patient¿s vessel tortuosity was ¿normal¿. However, as the core wire failed via torsional overload it is likely some excessive force was used. If information is provided in the future, a supplemental report will be issued.
Event Description
Medtronic received a report that the one pipeline experienced resistance in the hub of the phenom 27 microcatheter, two pipelines deployed in the catheter hub, and a third failed to open distally and broke during retrieval. The patient was undergoing flow diversion treatment for an unruptured, saccular aneurysm located in the left ica. The max diameter was 2. 9mm, and the neck diameter was 1. 5mm. The patient's vessel tortuosity was normal. The landing zone was was 3. 5mm distal and 4. 5mm proximal. The access vessel was the left ica, which was 3. 5-4. 5mm in diameter. It was reported that the first pipeline was inserted into the first phenom 27 catheter and deployed in the hub during insertion. The device was removed. A second pipeline was inserted into the catheter with extra precaution. This device had resistance in the catheter hub and also deployed in hub. The tip of the sheath had been seated securely in the hub. The second pipeline was removed along with phenom 27 catheter which was replaced with a new phenom 27. A third pipeline was inserted into the catheter and was able to be introduced into catheter. During deployment of this pipeline, the device would not open distally and had to be retrieved. The middle part of the pipeline had been positioned in a bend, and more than 50% had been deployed when it failed to open. The pipeline had been resheathed 2 or less times, and no further steps were taken to open the device. The third pipeline was removed back into introducer hub; however, unknown at the time, the 4. 75x12 pipeline had broken at the proximal bumper during retrieval. A fourth pipeline was introduced into the catheter. As device was being advanced, fluoro showed the tip of the third pipeline still inside the distal end of the phenom 27. The fourth pipeline 4. 25x12 was removed, and the phenom 27 was then removed with the third 4. 75x12 pipeline still inside. A new phenom 27 was then placed back in position. A fifth pipeline (4. 25x10) was then introduced into catheter. This device was able to be deployed safely and angiographically looked well apposed with good aneurysm stasis.  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 penumbra 8fr neuron max sheath, navien 058 guide catheter, and phenox portal 014 gui dewire. Additional information received reported that there was no damage observed to the catheter or pushwire. Additional information received reported that there was no damage observed to the catheter or pushwire.
