RebarRecalls & reported problems across all models

We found 4 models of Rebar by Micro Therapeutics, Inc. in the FDA's device registry (GUDID). Together they are named in 27 adverse event reports in the FDA's MAUDE database, received between Aug 17, 2019 and Sep 29, 2026 — classified as 1 injury, 26 malfunctions.

The most frequently reported specific device problem is “Physical Resistance/Sticking” (18 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.

  Medtronic received a report that a Solitaire AB stent was damaged during the procedure and encountered resistance The patient was undergoing surgery for treatment of a M1 ischemic stroke. The mRS baseline and procedure score was 1. The NIHSS baseline and post procedure score was 1. The TICI score baseline and post procedure was 0. IV TPA (intravenous tissue plasminogen activator) was not contraindicated. There were 2 passes with the device. It was noted the patient's vessel tortuosity was normal. Stroke onset to reperfusion time was 2 hours. It was reported that the patient had acute cerebral infarction and underwent thrombectomy in the right middle cerebral artery M1 segment. During the procedure, the SAB-6-30 was used for thrombectomy. During delivery through the middle segment of the Rebar18, the stent became stuck in the microcatheter. After the stent was removed, it was observed that the tail end of the stent had a kink, and the tail end of the stent was severely deformed. After the stent was replaced, the procedure proceeded smoothly. The reported device and any accessory devices were prepared as indicated in the instructions for use (IFU).

  MEDTRONIC RECEIVED A REPORT THAT THE OPERATOR PLANNED TO TREAT TERMINAL INTERNAL CAROTID ARTERY STENOSIS USING AN SAB-6-20 STENT. AFTER THE STENT DELIVERY MICROCATHETER (REBAR-18) WAS POSITIONED, DIFFICULTY WAS FELT DURING HYDRATION AND DELIVERY OF THE STENT, WITH A VERY ROUGH TACTILE FEEL INTRAOPERATIVELY. MULTIPLE ATTEMPTS WERE UNSUCCESSFUL, AND THE PROCEDURE WAS COMPLETED AFTER USING ANOTHER STENT INSTEAD. RESISTANCE OCCURRED IN THE MIDDLE SECTION OF THE CATHETER. THE REPORTED DEVICE AND ANY ACCESSORY DEVICES WERE PREPARED AS INDICATED IN THE INSTRUCTIONS FOR USE (IFU). NO PATIENT SYMPTOMS OR COMPLICATIONSWERE ASSOCIATED WITH THIS EVENT. THE PATIENT WAS UNDERGOING SURGERY FOR TREATMENT OF STENOSIS AT THE TERMINAL SEGMENT OF THE RIGHT INTERNAL CAROTID ARTERY. IT WAS NOTED THE PATIENT'S VESSEL TORTUOSITY WAS MODERATE. ADDITIONAL INFORMATION RECEIVED REPORTED RESISTANCE OCCURRED AT THE MIDDLE SECTION OF THE CATHETER. THERE WERE NOT ANY DAMAGES ON THE CATHETEROR THE PUSHWIRE OF THE SOLITAIRE, AND THE TIP OF THE SOLITARE WAS SECURED INTO THE HUB OF THE MICRO CATHETER.

  MEDTRONIC RECEIVED A REPORT THAT THERE WAS RESISTANCE DURING DELIVERY OF THE SOLITAIRE WITHIN THE MIDDLE OF THE REBAR-18 CATHETER. IN ADDITION, THE SOLITAIRE STENT WAS FOUND KINKED. THE PATIENT WAS UNDERGOING SURGERY FOR TREATMENT OF AN ISCHEMIC STROKE LOCATED IN THE LEFT INTERNAL CAROTID MIDDLE CEREBRAL ARTERY. THE MODIFIED RANKIN SCALE (MRS) SCORE AT BASELINE WAS 4, AND THE MRS SCORE AT THE TIME OF THE PROCEDURE WAS 4. THE NATIONAL INSTITUTES OF HEALTH STROKE SCALE (NIHSS) SCORE AT BASELINE WAS 16, AND 4 POST PROCEDURE. THE THROMBOLYSIS IN CEREBRAL INFARCTION (TICI) SCORE AT BASELINE WAS 0 AND 3 POST PROCEDURE. VASCULAR ACCESS WAS OBTAINED VIA THE FEMORAL ARTERY, WITH AN ACCESS VESSEL DIAMETER OF 10 MM. THE TIME FROM STROKE ONSET TO REPERFUSION WAS 5 HOURS. IT WAS NOTED THAT THE PATIENT¿S VESSEL TORTUOSITY WAS NORMAL. IT WAS REPORTED THAT THE PHYSICIAN WAS PERFORMING A LEFT-SIDED MIDDLE CEREBRAL INFARCTION SURGERY. THE PHYSICIAN CONSIDERED USING A STENT FOR THROMBECTOMY AND SELECTED AN SFR-4-20 STENT. HOWEVER, WHEN ENTERING THE MID-SECTION OF THE REBAR18 MICROCATHETER, SIGNIFICANT RESISTANCE WAS FELT WHEN THE STENT WAS WITHIN THE MICROCATHETER, AND THE STENT BECAME STUCK IN THE M

• MalfunctionApr 8, 2026Loss of or Failure to Bond; Retraction Problem; Patient-Device Incompatibility; Physical Resistance/Sticking

  MEDTRONIC RECEIVED A REPORT THAT THE PATIENT WAS UNDERGOING TREATMENT FOR THROMBECTOMY OF THE M1 SEGMENT OF THE RIGHT MIDDLE CEREBRAL ARTERY. IT WAS NOTED THAT THE PATIENT'S VESSEL TORTUOSITY WAS MODERATE. THE ACCESS VESSEL WAS THE FEMORAL ARTERY, WITH 8MM DIAMETER. IT WAS REPORTED THAT DURING THE THROMBECTOMY PROCEDURE, AFTER DEPLOYMENT OF THE THROMBECTOMY STENT, THE OPERATOR WAS UNABLE TO WITH DRAW THE REBAR 18 WHILE PULLING IT BACK THROUGH THE WALLABY INTERMEDIATE CATHETER. INTRAOPERATIVELY, THE OPERATOR PERCEIVED THAT THE RESISTANCE WAS CAUSED BY INTERACTION BETWEEN THE OUTER COATING OF THE REBAR AND THE INNER COATING OF THE INTERMEDIATE CATHETER, AND THE RESISTANCE WAS SIGNIFICANT IN THE MIDDLE SECTION. AFTER MULTIPLE FORCEFUL WITHDRAWAL ATTEMPTS, THE REBAR 18 WAS EVENTUALLY REMOVED. THE PROCEDURE THEN PROCEEDED SMOOTHLY, WITH SUCCESSFUL RECANALIZATION AND CLOT RETRIEVAL. THE REPORTED DEVICE AND ANY ACCESSORY DEVICES WERE PREPARED AS INDICATED IN THE INSTRUCTIONS FOR USE (IFU). NO PATIENT SYMPTOMS OR COMPLICATIONS WERE ASSOCIATED WITH THIS EVENT. ANCILLARY DEVICES INCLUDE A WALLABY 5F 125CM ESPERANCE INTERMEDIATE CATHETER.
