The devices were not returned for evaluation.Without return of the units it is not possible to determine if some damage or defect existed on the units that could have contributed to the event.It is not known if some procedural factors may have contributed to the event.No corrective actions will be taken at this time.Lot number was not provided; therefore, review of the manufacturing records could not be completed.A supplemental report will be forthcoming to cross reference the medwatch report for the reported event of obstruction.Per the ifu, the arterial embolectomy catheter is not recommended for the removal of fibrous, adherent, or calcified material (e.G.Chronic clot, atherosclerotic plaque).The catheter is not designed to withstand the additional force needed to remove these materials.Balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures.The possibility of balloon rupture must be taken into account when considering the risks involved any embolectomy procedure.As with all catheterization procedures, complications may occur.These may include local or systemic infection, local hematomas, intimal disruption, arterial dissection, perforation and vessel rupture, hemorrhage, arterial thrombosis, distal embolization of blood clots and atherosclerotic plaque, air embolus, aneurysm, arterial spasm, arteriovenous fistula formation, and balloon rupture with fragmentation and distal embolization.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.Yang, yu sung, et al."clinical experience with a hybrid procedure using the adherent clot catheter for salvage of thrombosed hemodialysis access: a comparison with the standard fogarty balloon catheter." vascular specialist international 31.1 (2015): 25.

It was reported that in a journal article published in 2014 and titled ¿clinical experience with a hybrid procedure using the adherent clot catheter for salvage of thrombosed hemodialysis access: a comparison with the standard fogarty balloon catheter¿.The study compared the efficacy of an adherent clot (ac) catheter to the standard balloon fogarty catheter for clot removal in thrombosed hemodialysis access, 4 cases of complications occurred in the fogarty catheter group.In the standard fogarty catheter group, there were 2 events reported with venous outlet rupture which were solved by performing a balloon angioplasty and 2 events with obstruction.Model and lot numbers are unknown.As well as any specific patient demographics.The devices were not saved for examination.
