Detaljerad beskrivning
The purpose of this trial is to evaluate the safety and effectiveness of the NovaCross™ micro-catheter when used to facilitate crossing of Chronic Total Occlusion (CTO) lesions in coronary arteries.
The procedure will be conducted on consenting patients diagnosed with a CTO in a coronary vessel that requires revascularization after a previously failed attempt to cross or refractory to 10 minutes of conventional guidewire attempt.

Intervention / Behandling |
|---|---|
|
Experimentell: 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.
