It was reported that the procedure was to treat a heavily calcified re-thrombosed stent.
After the 10x60mm armada 35 balloon dilatation catheter (bdc) was advanced to the lesion, and after several inflations of the balloon, between nominal pressure and above nominal, the balloon ruptured.
It was noted the rupture occurred due to the previously implanted stent had fractured and caused the balloon to rupture on contact.
During removal of the bdc resistance was met with the introducer and the central sheath of the balloon separated.
It was noted another unspecified armada 35 bdc was advanced; however, the same exact issue occurred and bdc ruptured at an unknown pressure.
Therefore, two fragments remained in the anatomy and the fragments were pressed against the vascular wall.
There was no adverse patient sequela reported and no clinically significant delay reported.
No additional information was provided.
