The physician was attempting to use an evercross pta balloon to treat a moderately calcified plaque lesion in the left mid common iliac artery.The lesion had chronic total occlusion (cto) and was 150 mm in length.The artery diameter is 6-7 mm with little tortuosity.It was reported that the device was prepped as per the ifu.A non-medtronic guidewire was used with a non-medtronic 5 fr sheath with no embolic protection.The balloon was inflated using non-medtronic inflation device with 50/50 contrast/ saline mix inflation fluid.The device was passed through a previously deployed stent and no excessive force was used.It was reported that there was no resistance when the balloon was advanced, and no issues were noted during inflation.It was reported that the device was slow to deflate at the lesion site (approx 10 seconds).Initially, the technician deflated the balloon and the angiograph revealed it was not fully deflated.Negative pressure was applied and it was again shown on the angiograph the balloon was not completely deflated.The balloon was initially inflated at 12 atm for 180 secs, the balloon was then repositioned slightly for second inflation at 10 atm for 180 secs.The decision was then made to remove the balloon within the sheath and the sheath was upsized to 6 fr.This event delayed the procedure by approximately three minutes and the balloon was retrieved intact.No patient injury was reported.

Device evaluation summary: the evercross was received with a small portion of the distal balloon chamber material bunched up just distal to the distal end of the 5-fr sheath.Sanguine residue was noted on the exterior of the dilatation catheter.A 20cc water filled syringe was attached to the evercross proximal hub luer lock and the guidewire lumen was flushed: sanguine tinted fluid was observed exiting the distal end of the dilatation catheter.The dilatation catheter was flushed until the fluid ran clear and freely.A 0.035¿ guidewire was loaded with ease through the distal tip of the dilatation catheter and out the proximal hub luer lock.The guidewire loaded evercross dilatation catheter was advanced distally out of the 5-fr sheath.Except for the distal end of the balloon chamber the balloon chamber was tightly wrapped and covered with sanguine residue.A 10cc water filled syringe was attached to the inflation lumen luer lock on the y-manifold and the balloon chamber was inflated.The balloon chamber was rinsed with running water in a sink to allow examination of the balloon chamber.A 20cc water/glycerin (50:50) filled syringe with manometer was attached to the inflation lumen luer lock on the y-manifold and the dilation catheter was inflated to nominal pressure of 8-atm.The evercross was then inflated to its rated bursting pressure of 12-atm.No leaks or abnormalities were noted in the dilatation catheter.The evercross was then deflated by drawing a vacuum with the 20cc syringe with manometer.The evercross dilation catheter balloon chamber fully deflated in 19-seconds.The full length of the balloon chamber was able to pass through a 5-fr catheter hole gauge.The guidewire loaded evercross was pulled into the 5-fr sheath but the balloon material began to bunch up and the 5-fr sheath began to accordion fold in random zones along its length.Even with the guidewire removed the evercross dilatation catheter could not be removed from the 5-fr sheath.If information is provided in the future, a supplemental report will be issued.
