As reported, a 7mm x 4cm 190 cm saberx radianz percutaneous transluminal angioplasty (pta) balloon catheter was unable to deflate after inflation in the body despite the application of negative pressure.Pressure could still be applied while the balloon remained inflated.Negative pressure was continuously applied, and after the pressure dropped slightly, the device was pulled back to the aorta and intentionally ruptured using the back end of the guidewire to complete the procedure.There was no reported patient injury.There was no problem during device preparation.There was no difficulty removing the protective balloon cover or any sterile packaging components, and a contralateral approach was not used.The device was used during pcps removal.The target vessel was the femoral vein.At the target site, the vessel characteristics included no calcification, moderate tortuosity, 50% stenosis, a moderate acute angle, and moderate bifurcation.The vessel characteristics for accessing the target site included no calcification, no tortuosity, no stenosis, no acute angle, and moderate bifurcation.The device was not placed into an acute bend at any point during the procedure, successfully crossed the lesion, and did not kink at any time.No anomalies were noted after the device was delivered to the lesion.The physician requested an investigation into why pressure could be applied but negative pressure could not achieve deflation and requested evaluation of the lumen because the device was intentionally ruptured.The device will be returned for evaluation.
