As reported, the balloon on a 1.25mm x 15mm saberx.014 percutaneous transluminal angioplasty (pta) balloon catheter ruptured at approximately 7 atmospheres (atm) during dilation of the dorsalis pedis artery.Another 1.25mm x 15mm saberx.014 pta balloon catheter was used; however, the balloon ruptured again at approximately 13 atmospheres (atm).A non-cordis 1.5mm balloon catheter was then used as a replacement and was able to complete the procedure.There were no reported injuries to the patient.This was during a procedure to treat stenosis of the left superficial femoral artery (sfa), the anterior tibial artery, and the dorsalis pedis artery.The target vessel was characterized by moderate to severe calcification, moderate tortuosity, and 100% stenosis.An unknown 6f guide sheath was inserted from the left groin, and an unknown.014 guidewire was used to cross the lesion.The devices were stored and prepped per the instructions for use (ifu), and there was no difficulty removing any sterile packaging components or protective balloon covers.The devices maintained negative pressure during preparation.Both saberx.014 pta balloon catheters were able to cross the lesion prior to inflation.For both the first and second saberx.014 devices, neither was put into an acute bend nor kinked during the procedure, and each device was easily removed from the patient and retrieved intact in one piece.The devices were discarded and will not be returned.

After further review of additional information received the following sections have been updated accordingly: b4, g3, g6, h1, h2, h3, h6, h10, and h11.Complaint conclusion: as reported, the balloon on a 1.25mm x 15mm saberx.014 percutaneous transluminal angioplasty (pta) balloon catheter ruptured at approximately seven atmospheres (atm) during dilation of the dorsalis pedis artery.Another 1.25mm x 15mm saberx.014 pta balloon catheter was used; however, the balloon ruptured again at approximately 13 atmospheres (atm).A non-cordis 1.5mm balloon catheter was then used as a replacement and was able to complete the procedure.There were no reported injuries to the patient.This was during a procedure to treat stenosis of the left superficial femoral artery (sfa), the anterior tibial artery, and the dorsalis pedis artery.The target vessel was characterized by moderate to severe calcification, moderate tortuosity, and 100% stenosis.An unknown 6f guide sheath was inserted from the left groin, and an unknown.014 guidewire was used to cross the lesion.The devices were stored and prepped per the instructions for use (ifu), and there was no difficulty removing any sterile packaging components or protective balloon covers.The devices maintained negative pressure during preparation.Saberx.014 pta balloon catheters were able to cross the lesion prior to inflation.For both the first and second saberx.014 devices, neither was put into an acute bend nor kinked during the procedure, and each device was easily removed from the patient and retrieved intact in one piece.The devices were discarded and will not be returned.A product history record (phr) review of lot 2506199594 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 verified as the devices were not returned for analysis.The exact cause could not be determined.Vessel characteristics of calcification with 100% stenosis likely have contributed to the reported events, as damage to balloon material may have occurred during crossing or upon inflation.However, without the return of the devices for analysis, it is difficult to draw a clinical conclusion between the devices and the events reported.According to the instructions for use, which are not intended to mitigate risk, ¿carefully inspect the catheter prior to use to verify that the catheter has not been damaged and that its size, shape and condition are suitable for the procedure for which it is to be used.Flush or rinse all products entering the vascular system with sterile isotonic saline or a similar solution via the guide-wire access port prior to use.Never attempt to move the guide wire when the balloon is inflated.Do not advance the catheter against significant resistance.The cause of resistance should be determined via fluoroscopy.Inflation in excess of the rated burst pressure may cause the balloon to rupture.Use the recommended balloon inflation medium (25% contrast medium/75% sterile saline solution).It has been shown that a 25/75% contrast / saline ratio has yielded faster balloon inflation / deflation times.Never use air or other gaseous medium to inflate the balloon.If resistance is felt during post procedure withdrawal of the catheter through the introducer sheath, determine if contrast is trapped in the balloon with fluoroscopy.If contrast is present, push the balloon out of the sheath and then completely evacuate the contrast before proceeding to withdraw the balloon.If resistance is still felt during post procedure withdrawal of the catheter, it is recommended to remove the balloon catheter and guidewire/ introducer sheath as a single unit.Do not continue to use the balloon catheter if the shaft has been bent or kinked.¿ neither the phr¿s nor the information available suggests a design or manufacturing related cause for the reported events.Therefore, no corrective or preventive action will be taken at this time.
