As reported, it was not possible to retract the 10 mm x 4cm x 135 powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter through a non-cordis sheath after successful intervention of superficial femoral artery (sfa) occlusion.The sheath was removed together with the powerflex, and manual compression was performed.There was no reported patient injury.The device was stored, handled and prepped according to the instructions for use (ifu).There was no difficulty removing the product from the hoop or difficulty removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.No kinks or other damages were noted prior to inserting the product the product into the patient.The device prepped normally; maintained negative pressure.There was neither resistance/friction while inserting the balloon through the rotating hemostatic valve or while inserting the balloon through the guide catheter nor difficulty advancing the balloon catheter through the vessel.The balloon was deflated several times to get it through the sheath.The device is expected to be returned for evaluation.
