As reported, a 4mm x 22cm 135cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was found to be cracked during a balloon inflation to 10 atmospheres (atm).
As a result, the balloon was immediately deflated and the device was replaced with another 4mm x 22cm cordis balloon catheter to complete the procedure.
There was no reported injury to the patient.
This was during a procedure to treat a 70% stenosis in the superficial femoral artery (sfa) in which the powerflex pro pta balloon catheter was used for pre-dilation of the lesion.
There was no calcification or tortuosity to the target vessel and the lesion was not a chronic total occlusion (cto).
There was no difficulty removing the product from the hoop, protective balloon cover, the stylet, or any of the sterile packaging components.
The device maintained negative pressure during preparation and an unknown inflation device was prepped with bayer contrast at a 1:1 contrast to saline ratio.
The same, unknown inflation device was used successfully with other devices during the procedure.
There was no resistance or friction experienced as the balloon entered the patient.
There was no difficulty advancing the balloon catheter through the vessel, no difficulty crossing the lesion, and the device was never in an acute bend.
The crack was visualized by evidence of an outflow of contrast agent form the device; however, the device did not separate as a result of the damage and was removed in one piece.
Additionally, there was a noticeable drop in atmospheres upon the crack to the device.
The device will be returned for evaluation.
