Physician was attempting to use a chocolate pta balloon along with non-medtronic 6fr 45cm sheath and guidewire during procedure to treat a mildly calcified fibrous lesion in the right mid superficial femoral artery (sfa).
The vessel diameter and lesion length were 4mm and 100mm respectively.
An indeflator was used for balloon inflation.
Mixture of contrast and physiological saline was used as inflation fluid.
The product did not have any malfunction when it was taken out of the package.
The device was prepped per ifu with no issues noted.
It was reported that during balloon inflation, it was difficult to inflate the balloon at 9atm.
Balloon deflation difficulty also occurred.
The device would not deflate at the lesion site.
Deflation issue was noted during subsequent inflation.
The device did not pass through a previously deployed stent.
There was no resistance encountered when advancing the device.
When at the lesion site the balloon was first inflated to 9atm with the chocolate balloon 4-120mm, inflation failure was confirmed in the center of the balloon.
Physician removed the balloon from the body, tested for inflation, and tried again to inflate at the lesion site after confirming that the balloon was firmly inflated.
The balloon inflated to 8atm at the lesion site, and deflation was attempted, but failed to deflate even after 30 minutes.
The distal part of the superficial femoral artery was pierced with a puncture needle from the body surface, and the chocolate balloon with poor deflation was broken and retrieved.
Patient injury was reported with hemorrhage/bleed at access site.
