Fracture concentric and eccentric calcium, change fibrotic lesion compliance¹, avoid plaque shift in ostial and bifurcation, and reduce restenosis in small vessels. With over 30 years of clinical evidence, the WOLVERINE Coronary Cutting Balloon is proven to deliver unmatched clinical versatility.

See it to believe it

This 1 min video demonstrates how the WOLVERINE Coronary Cutting Balloon creates controlled calcium fractures for predictable results.

Fixed, microsurgical atherotomes

Discover a new level of control. WOLVERINE is the only balloon with atherotomes that can anchor to tissue and precisely dilate noncompliant lesions at low pressures, and with low risk of vessel trauma. By creating controlled microincisions, WOLVERINE safely minimizes elastic recoil in resistant lesions. 

A proven mechanism of action³

Discover the key benefits of WOLVERINE's intentionally designed microsurgical atherotomes:



Minimize elastic recoil for more even expansion lines.



Secures device in place to reduce the risk of balloon and plaque shift.

WOLVERINE vs. NC balloon⁴

WOLVERINE Demonstrates Superior Tensile Stress Control vs. NC Balloon

Cutting Balloon vs. NC Balloon

The Wolverine coronary cutting balloon's added microsurgical atherotomes focus stress in three distinct areas to create controlled, predictable calcium fractures.

This is in contrast to the NC Balloon, which shows a much lower stress distribution when used at the same 12 ATM inflation pressure. Even at 20 ATM, the stress is still much lower and unfocused, leading to uncontrolled fractures.⁴

Lower arc of calcium = lower Shockwave™ efficacy.⁵

IVL doesn't always cut it

Device orientation directly impacts the probability of effective fractures. 

When it comes to prepping eccentric plaque, IVL often falls short. The DISRUPT CAD III OCT Sub study showed that reduced arc of calcium directly corresponds to reduced Shockwave fracture effectiveness.⁵

Clinical Evidence in Calcified CAD Lesions

WOLVERINE is the only device clinically proven to provide superior MSA at the calcium site compared to POBA with no significant difference in procedural complications or 1-year MACE in a randomized clinical trial.

Operators achieved higher acute lumen gain in severely calcified lesions with combination of rotational atherectomy and modified balloons as compared to atherectomy or modified balloon alone.

In >180-degree arc calcium, WOLVERINE plus rotational atherectomy increased mean minimum stent CSA, with lower rates of TVR and MACE.
