The most frequently reported specific device problem is “Detachment of Device or Device Component” (17 reports).

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

  USER FACILITY VOLUNTARY MEDWATCH REPORT (MDR REPORT #: MW5117196) WAS RECEIVED VIA THE US DISTRIBUTOR ON MAY 10, 2023. IT WAS REPORTED THAT THE TIP OF AN ASAHI PROWATER GUIDE WIRE BROKE OFF DURING A PERCUTANEOUS CORONARY INTERVENTION TO TREAT A HEAVILY CALCIFIED 90-99% STENOSIS IN THE OSTIUM OF THE RAMUS ARTERY ARISING FROM THE LEFT MAIN (LM). DURING THE PROCEDURE, THE PROWATER WIRE WAS USED IN AN ATTEMPT TO PLACE A DRUG ELUTING STENT. WHEN THE PROWATER WIRE WAS PROTRACTED, IT WAS NOTED TO HAVE COME BACK AND THE TIP OF THE WIRE WAS SEEN EMBOLIZED TO THE DISTAL RAMUS. THE STENT REMAINED PARTIALLY IN THE LM. GIVEN THE NON-OBSTRUCTIVE LM DISEASE, FURTHER MANEUVERS WERE FELT TO BE UNSAFE. THE DECISION WAS MADE TO LEAVE THE RAMUS AS A PTCA ALONE. GIVEN THE WIRE FRAGMENT WAS VERY DISTAL, ATTEMPTS TO SNARE THE FRAGMENT WERE FELT TO BE HIGH RISK FOR CAUSING ISCHEMIA AND VESSEL INJURY. IT IS ESTIMATED THAT THE RETAINED FRAGMENT MEASURES APPROXIMATELY 2.5 CM. NO IDENTIFIED ADVERSE OUTCOMES TO DATE. PATIENT DISCHARGED TO HOME WITHOUT HARM RELATED TO THIS EVENT.
