As reported, there was difficulty advancing a 5mm x 15cm 155cm saberx percutaneous transluminal angioplasty (pta) balloon catheter towards a shunt lesion.
The device was able to cross the lesion; however, after an inflation to 8 atmospheres (atm), the balloon was unable to be deflated.
As a result, the physician pulled the balloon back to a point where an intentional separation of the device could be made in order to deflate the balloon and remove the device.
It was reported that none of the device pieces had been left inside of the patient and the procedure was completed after its their removal.
This was during a pta procedure to treat a shunt lesion in the axillary vein.
The lesion had mild calcification, mild tortuosity, a 99% stenosis, and was not a chronic total occlusion (cto).
The device was stored and prepped per the instructions for use (ifu) and maintained negative pressure during preparation.
There was no difficulty removing the device from the hoop, removing the protective balloon cover, the stylet, or any of the sterile packaging components and the device was not kinked or damaged in any way prior to being inserted into the patient.
There was no resistance or friction as the balloon catheter was being inserted into the patient, the device was never in an acute bend, and there were no kinks observed on the device.
Information regarding the contrast used, contrast to saline mixture, type of inflation device used, guidewire used was requested but was not provided.
Additionally, procedural films were requested but are unavailable.
The device will be returned for evaluation.
