(b)(6) clinical study.
It was reported that the balloon over extended during inflation.
In (b)(6) 2020, the index procedure was performed.
The target lesion was in the right peroneal artery with 99% stenosis, proximal and distal reference vessel diameter was 3.
25 mm and 3.
0 mm respectively with a length of 60 mm.
As a treatment, orbital atherectomy was performed.
Post atherectomy, balloon angioplasty was attempted with sterling balloon but there was significant 'watermelon seeding' of the irregular balloon.
The balloon was withdrawn and the lesion was treated with a 4.
0 mm x 15 mm cutting balloon to pre-dilate the lesion at burst pressures with a 20% residual stenosis.
Post pre-dilation, the lesion was further treated with placing a 3.
5 mm x 80 mm study stent.
Post dilation was performed with residual stenosis of 0%.
