Event Description

It was reported that the blade was partially peeled off.Vascular access was via common femoral artery.The 50% stenosed target lesion was located in the moderately tortuous renal artery.A 4.00mm/1.5cm/140cm small peripheral cutting balloon was selected for use in pre-inflation.During procedure, the inflation was performed 3 times and the maximum inflation pressure was at 7atm.During removal of the device, a mild resistance was noted.Furthermore, the device was simply pulled out from the patient's body without any issues and it was noted that proximal part of the blade was partially lifted.Moreover, the two blades of this recovered device were peeled off, but this was intentionally peeled off outside the body.No device fragment remained inside the body.No patient complications were reported.

E1 - initial reporter city: (b)(6).Device evaluated by mfr: a visual and microscopic examination was performed on the returned device.It was noted that one of the blades and pad was completely detached from the balloon material and it was also noted that a section of another of one of the blades and pad, approximately 4mm in length on the proximal end was detached and was not returned with the device.The remaining section of blade was undamaged and fully bonded to the balloon material.The damage identified can potentially be a result of the resistance encountered during withdrawal of the device.All other blades were intact and fully bonded to the balloon material.A visual and microscopic examination identified no issues with the balloon material.No issue was observed with the tip or markerbands of the device which could have contributed to the complaint incident.A visual and tactile examination identified a shaft polymer extrusion kink 20mm proximal from the guidewire exit port.No other issues were identified during the product analysis.
