Nitinol in Magnetic Resonance Imaging

Minimally Invasive Therapy & Allied Technologies, 2004
Surgical and interventional instruments as well as implants can cause significant magnetic resonance image (MRI) artifacts. The artifacts can be used to visualize instruments, cannulae, guide wires, catheters during interventional MRI and Nitinol devices have proven to be useful for MRI procedures. Diagnostic imaging is often compromised in the area of

Fatigue Fracture of Nitinol

Journal of Failure Analysis and Prevention, 2021
Abstract Nitinol fatigue fracture surfaces generally exhibit similar features to most engineering alloys, including a flat fracture plane, ratchet marks, radial lines, beachmarks, and striations.

Metallographic method for nitinol

Metallography, 1985
Abstract It is demonstrated that for the alloy Ni-Ti, mechanical polishing followed by electrolytic polishing using a jet polisher such as the Struers Tenupol produces areas suitable for microscopical examination of the structure with polarized light illumination.

Nitinol Stents in Hemodialysis Access

Journal of Vascular and Interventional Radiology, 2004
MAINTAINING permanent vascular access remains the Achilles heel of hemodialysis. In the era of widespread use of percutaneous angioplasty and thrombectomy for salvaging failing and failed hemodialysis accesses, the consensus guidelines of the National Kidney Foundation Dialysis Outcomes Quality Initiative recommend relatively modest benchmarks: a 50% 6-

Fractography of Nitinol

Abstract This article focuses on the fractography of Nitinol, a shape memory alloy of nickel and titanium, in superelastic biomedical applications, which primarily comprise drawn and/or laser-cut wire and tube components. Overload fracture, hydrogen embrittlement fracture, and fatigue fracture are discussed in detail.

Martensitic transformation in nitinol

Metallography, 1985
Abstract Optical metallographic evidence is presented for the formation of martensite, and reversion of the martensite to the β phase in nitinol during thermal cycling and during shape memory behavior.

Non‐medical applications of NiTinol

Minimally Invasive Therapy & Allied Technologies, 2004
Shape memory alloys based on the intermetallic system Nickel-Titanium (NiTi or NiTinol) are widely used in various kinds of industries. At present, the most popular market is medical industry, in which NiTinol finds a perfect environment with a narrow temperature specification ranging from room to body temperature.
