The returned instrument was subjected to a technical analysis and the corresponding production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for the reported event.The technical investigation of the returned orsiro mission revealed that the guidewire lumen is slightly clogged with dried blood at its proximal end.After dissolving these blood clots with clean water, a 0.014 inch reference guidewire and a 0.015 inch transportation wire could be completely introduced from distal without noticeable friction.Review of the production documentation confirmed that the instrument was manufactured according to specifications and passed all in-process and final inspections.The device has been delivered with a 0.015 inch transportation wire and no difficulties in removing this wire have been reported.Based on the conducted investigations of the device being subject to this complaint, no material or manufacturing related root cause could be determined.
