This report is being submitted as follow up no.1 to provide additional infomration to secton b5, the device return date in section d9, update section h3, and to provide the completed investigation results.From the provided photo, it was found that the actual catheter was cut off in two places, and there was a cut piece.No missing part was found in the distal section.The returned sample had only its distal side, and no cut piece.Its hand side was returned.Visual inspection of the actual sample found that it had been cut off at approximately 910mm from the distal end.No missing part was found in the distal section.Magnifying inspection of the cut section found that the stainless-steel reinforcement had been exposed, and the cut section had been crushed into an oval shape.The outer and inner diameters of the actual sample (normal sections) were measured and confirmed to meet the specifications.The following simulation test was performed in the past.A factory-retained progreat was inserted into a factory-retained angiographic catheter (glidecath, with a stopcock).The operation of closing the stopcock by approximately 90 ° was performed.After operating the stopcock, the progreat was removed from the angiographic catheter and visual inspection of it was performed.It was found that the catheter was cut off in two places at the stopcock operating section, and there was a cut piece.This was very similar to the condition in the provided photo.The length of the cut piece was approximately 6mm.Magnifying inspection of the cutting section found that the stainless-steel reinforcement was exposed, and the cutting section was crushed in an oval shape.It was very similar to the condition of actual sample.Based on the investigation result, as a possible cause of this complaint, it was likely that since the stopcock was operated with the actual sample inserted in the device used in combination (e.G., angiographic catheter with a stopcock), the actual sample was caught in the stopcock and was cut off.Relevant ifu reference: "if the guiding catheter is fitted with a stopcock, do not close the stopcock with the catheter inside the guiding catheter.The catheter may be broken.".
