Crosser IQ Ultrasonic Flashcards
What mechanism of action does Crosser IQ use?
Ultrasonic vibration allows Crosser IQ to automatically and selectively ablate plaque, while remaining atraumatic to elastic tissue
What are the (3) primary CTO challenges?
Inability or failure to:
1. penetrate the proximal cap
2. navigate side branches/collaterals
3. re-enter distal true lumen
What are (7) potential consequences of subintimal crossing?
- Vessel perforation
- Embolization
- Dissection
- Hematoma
- Compromise important collaterals
- Prolonged lesion treatment length
- Accelerated healing process from vessel injury can lead to restenosis
True or False: the proximal portion of a CTO is easier to cross than the distal portion
False
If an antegrade approach is not working for a CTO, what is another access that could be a solution?
Pedal access
True or False: If you cannot cross the lesion, you cannot treat the lesion
True
What is the % range of conventional wire and catheter crossing in SFA lesions?
50% - 90%
Approximately how much $$ is the total CTO category worth?
$83.8 million
What category share % does Crosser have?
27.6% (#2) behind Medtronic Viance (33.6%)
What is the ASP for Crosser?
