As reported, the 4mm 10cm 150 saber rapid exchange (rx) percutaneous transluminal angioplasty (pta) used for post dilation of an unknown stent in the popliteal artery, ruptured.There was no reported patient injury.A brachial approach was initially made.The device will not be returned as it was discarded by the hospital.

After further review of additional information received the following sections g4, g7, h2, and h6 have been updated accordingly.A saber rapid exchange (rx) 4mm x 10mm 150cm percutaneous transluminal angioplasty (pta) balloon catheter was used for post dilation of an unknown stent in the popliteal artery and ruptured.There was no reported patient injury.A brachial approach was initially made.The device was not returned for analysis as it was discarded.A product history record (phr) review of lot 17654395 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon- burst¿ could not be confirmed as the device was not returned for analysis.Based on the limited information provided, it is not possible to draw a conclusion about a clinical relationship between the device and the event however procedural/handling factors and vessel characteristics (although unknown) might have contributed to the reported event as the potential presence of calcification is known to cause damage to balloons.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.At least (b)(4) of the balloons (with a (b)(4) confidence) will not burst at or below their rated burst pressure.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/preventive action will be taken at this time.
