Microcatheters for antegrade CTO approach
Finecross 130/150cm
Corsair Pro 135/150cm
M-Cath 135cm
Turnpike Spiral 135/150cm
3. Microcatheters for antegrade CTO approach
Less Guiding Back up
Ostial or very proximal lesions,
planned ADR
Good Guiding Back up
Not very calcified CTO lesions
Finecross
M-Cath
Corsair
Turnpike Spiral
Rotatable MCPushable MC
11. Over-rotation of MC in calcified lesion:
Wire and MC entrapment: Corsair-TIP with Confianza 12g
12. Complications in collaterals – Over-rotating the MC
Do not force an
over-rotation of the
MC in tortuosity
www.youtube.com: Case 64: Manual of CTO Interventions, 2nd edition
13. 1) Do not use a MC which you
have to push in tiny
collaterals and severe
angulations
2) A rotatable MC may be safer
(Turnpike LP, Corsair)
Complications in collaterals – Pushing MC in
tortuosity
25. Design
Balloon
0.6 x 5 (mm)
30 ATM rated
Shaft
OD ≤ 1.5F
High push shaft
Best in class shaft profile
5. Scoring design
Short Rx section
Guidewire used as scoring
element
Tip
Low profile
High penetration
95 cm and 105 cm exit markers

47. CTO Wiring Back up force Calcification
and
tortuosity
Subintimal
tracking
Finecross 1,8F Very good
feedback on the
wire tip, due to
low resistance in
the MC
Low active back
up, good push
Very flexible
shaft, low
profile,
Crossing success
depending on
guiding back up
force
Requires almost
very good
guiding back up
Corsair 2,6F Over-rotation of
the wire and MC
may cause wire
and device
entrapment
Very good active
back up
Attention! Do
not over-rotate
Very good
performance in
subintimal;
Power knuckle
may cause tip
prolaps
Turnpike Spiral 2,9F Over-rotation
may cause
device
entrapment
Best active back
up
Excellent in
fibrotic tissues,
like In-Stent-
Occlusion
Excellent back
up in subintimal
space
Antegrade Microcatheter
48. The is a CTO Scoring Balloon intended to create Initial Opening in heavy calcified/
fibrotic occlusions where the primary crossing is an issue.
