NiTinol: A Review of its Smart Properties that Make it a Smart Alloy and a Strong Ally in Endovascular Neurosurgery

Indian Journal of Neurosurgery
Nitinol is an equiatomic alloy of nickel and titanium. Its unique properties like “superelasticity” and “shape memory” have made it one of the most commonly used materials for manufacturing hardware in endovascular neurosurgery.

Trans‐Patch Retrograde Re‐Entry During Hybrid Revascularization of an External Iliac Artery Chronic Total Occlusion: A Technical Note and Review of Re‐Entry Strategies

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Failure of true‐lumen re‐entry after subintimal wire passage is a well‐recognized limitation of endovascular treatment for external iliac artery (EIA) chronic total occlusions (CTO). We report a 73‐year‐old woman with severe limb ischemia and a prior failed endovascular attempt who underwent hybrid left common femoral artery (CFA ...
