As reported, the balloon of a saber rx 4mm 20cm 155 ruptured at 4 atm during post dilation.There was no reported injury to the patient.The saber pta was stored in-hospital sanitary area storage.No abnormalities were found on the exterior and interior tray of the device.The lesion was the right superficial femoral artery.An approach was made from the left femoral.A guidewire crossed the lesion and the lesion was checked by ultrasound ivus.A saber 4x60 was fully inflated due to lesion in tandem.The lesion was noted not t have severe calcification.The device will not be returned for evaluation as it was discarded.Additional information was requested; however, the information could not be obtained.

After further review of additional information received the following sections have been updated accordingly: b5, d4, g3, h1, h2, h3 and h6 as reported, the balloon of a saber rx 4mm 20cm 155 ruptured at four atm during post dilation.There was no reported injury to the patient.The saber pta was stored in-hospital sanitary area storage.No abnormalities were found on the exterior and interior tray of the device.The lesion was the right superficial femoral artery.An approach was made from the left femoral.A guidewire crossed the lesion, and the lesion was checked by ultrasound ivus.A saber 4x60 was fully inflated due to lesion in tandem.The lesion was noted not to have severe calcification.The device will not be returned for evaluation as it was discarded.Additional information was requested; however, the information could not be obtained.The product was not returned for analysis as it was discarded due to hospital regulation.A product history record (phr) review of lot 82186283 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon burst-at/below rbp¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Vessel characteristics, although unknown and procedural factors likely contributed to the reported event.However, with the limited amount of information available regarding lesion characteristics and without the return of the device for analysis it is difficult to draw a clinical conclusion between the device and the event reported.According to the warnings in the safety information in the instructions for use ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.To reduce the potential for vessel damage or the risk of dislodgement of particles it is very important that the inflated diameter of the balloon should approximate the diameter of the vessel just proximal and distal to the lesion.The balloon dimensions are printed on the product label.The compliance table incorporated with the product shows how balloon diameter increases as pressure increases.Do not exceed the rated burst pressure recommended on the label.The rated burst pressure is based on the results of in vitro testing.(b)(4).Use of a pressure monitoring device is recommended to prevent over-pressurization.Pressure in excess of the rated burst pressure can cause balloon rupture and potential inability to withdraw the catheter through the introducer sheath.Balloon rupture can cause vessel damage and the need for additional intervention.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).Never use air or any gaseous medium to inflate the balloon.¿ neither the phr nor the information available suggests a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
