Eksperimentel: NovaCross
NovaCross microcatheter will be used.
|
The NovaCross™ is a guidewire positioning and support microcatheter for improving chronic total occlusion (CTO) crossability.
The NovaCross™ gains its supportive characteristics through the use of a unique operator-controlled Nitinol scaffold and an extendable segment, both at its distal tip.
