Minimally Invasive Therapy and Allied Technologies, 2000
This review links together recent information on the biocompatibility of Nitinol. Fundamental aspects of biological responses to Nitinol and its alloy components are clarified. The clinical advantages of using this functional biomaterial are evident. Although most studies support the good biocompatibility of Nitinol, there are still a lot of unanswered

Minimally Invasive Therapy & Allied Technologies, 2004
The present contribution focuses on the structural modelling of Nitinol devices. Apart from a powerful material modelling which should consider the well-known phenomena pseudo-elasticity, pseudo-plasticity and the shape memory effect a computationally efficient finite element implementation is needed.

Surface Modifications of Nitinol
Journal of Long-Term Effects of Medical Implants, 2009Nitinol (an acronym for the Nickel-Titanium Naval Ordnance Laboratory) has been extensively explored as an implant material for the medical industry. The potential problem with Nitinol implant devices is the release of Ni in the human body, which has stimulated a great deal of research on surface modifications and the application of coatings.

The Chemical Educator, 1997
The shape-retaining alloy Nitinol (Nickel Titanium Naval Ordance Laboratory), the “metal with a memory,” is revolutionizing manufacturing, engineering, and medicine as countless products that “think” for themselves enter the marketplace. This article recounts its discovery in 1959 by William J. Buehler of the U.S.

Journal of Applied Physics, 1987
A self-consistent macroscopic thermodynamics is developed for the calculation of work, heat, and dissipation for thermodynamic paths of the shape memory alloy, Nitinol. The thermodynamic system analyzed is a Nitinol helix for which extensive force–length–temperature (FLT) equation of state measurements have been made.

Susceptibility of Nitinol to Localized Corrosion
Journal of Biomedical Materials Research - Part A, 2006AbstractThe effect of different conditions on the susceptibility of nitinol to localized corrosion was examined using the cyclic potentiodynamic polarization technique. Tests were performed on mechanically polished (MP) and electropolished (EP) nitinol wire in 0.9 wt % NaCl and phosphate‐buffered saline (PBS). A polarization curve was also obtained for

Nitinol for Prosthetic and Orthotic Applications
Journal of Materials Engineering and Performance, 2011As global populations age, conditions such as stroke and diabetes require individuals to use rehabilitation technology for many years to come due to chronic musculoskeletal, sensory, and other physical impairments. One in four males currently aged 45 will experience a stroke within 40 years and will often require access to prolonged rehabilitation.

Bending characteristics of nitinol wire
American Journal of Orthodontics, 1979U ntil recently only a limited group of alloys have been used for orthodontic wires, namely, gold-caper, austenitic stainless steel, and chromium-cobalt-nickle (CrCo-Ni) based materials. In general, the last two groups have similar mechanical properties although processing, stress-relieving, heat-treating, and minor alloying adjustments allow for small

Fatigue and Durability of Nitinol Stents
Journal of the Mechanical Behavior of Biomedical Materials, 2008Nitinol self-expanding stents are effective in treating peripheral artery disease, including the superficial femoral, carotid, and renal arteries. However, fracture occurrences of up to 50% have been reported in some stents after one year. These stent fractures are likely due to in vivo cyclic displacements.
