Manufacturer Narrative

The fogarty catheter involved in this case was received at our product evaluation laboratory for evaluation.Report of "balloon couldn't be deflated" was confirmed.The balloon was inflated with 0.9 milliliters ro water and the balloon inflated concentric and did not leak.However, balloon could not deflate completely after 60 seconds (aided with water).The maximum deflation time is 15 seconds (aided with water).Balloon deflation time with water was out of specification.Then, cut down was performed on the catheter body to locate occlusion.Balloon inflation lumen was found to be collapsed near the proximal bushing.Balloon latex, bushings and windings were intact.Through lumen was patent without any leakage or occlusion.No visible damage was observed from catheter body.
