Batch history review: no other complaint have been reported on this batch of guidewires sold since 2015.Investigation: the involved guidewire was sent to the manufacturer for evaluation.The other implantation accessories are not available.The j guidewire is completely unravelled and broken at its distal extremity.The welded tip is missing.Conclusion: the defects observed on the returned device seem to show that the guidewire remained blocked inside the 18g seldinger needle or inside the introducer dilator.Then the physician continued to pull on it to remove it.This blockage is generally due to the fact that the physician attempted to withdraw the guidewire through one of these accessories.The ifu's specify : "to prevent shearing of the guide-wire never withdraw the j guide-wire through the seldinger needle.Remove the guide-wire and the dilator together.Do not remove the guide-wire through the dilator as this may result in the guide-wire unravelling." this is a known risk of access port implantation.This incident is isolated.No corrective action is envisaged.
