Superelastic endocardiac multi-electrode

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
Recently developed electrode arrays have advantages for multi-site recordings used in endocardiac mapping. The number of electrodes is limited by a difficult to handle technology causing the price per array to increase. Recent progress in computing methods allow us to simplify the electrode manufacturing process, making available 1024 electrodes or ...

Superelastic softening in perovskites

Physical Review B, 2011
Contrary to high frequency (MHz-GHz) elastic data, at low frequencies (0.1-50 Hz) huge elastic softening (superelasticity) is usually found in the low symmetry improper ferroelastic phases (i.e., tetragonal or rhombohedral) of perovskite structured materials including SrTiO3, KMn1-xCaxF3, and LaAlO3.

An overview of superelastic stent design

Minimally Invasive Therapy & Allied Technologies, 2000
The purpose of this paper is to contrast the performance of self-expanding and balloon-expandable stents. While both approaches to stenting have proven to be successful in treating a wide range of vascular disease, there are significant differences in the philosophy behind and properties of the two types of stents.

Bending of Beams in Superelasticity Domain

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractThe paper deals with bending of beams made of shape memory material (SMM). The research is focused on the modelling of a bending process in the superelasticity region, which w one of the characteristics of SMM. On the basis of a chosen physical model, a computer program has been set up for numerical modelling of the stress‐strain and ...

The utility of superelasticity in medicine

Bio-Medical Materials and Engineering, 1996
Nitinol alloys (Nitinol) exhibit a dramatically enhanced elasticity, known as “superelasticity”, which is becoming integral to the design of a variety of new medical products. Elasticity is the most apparent of the advantages afforded by this material, but by no means the only or most important.

Cellular stretch reveals superelastic powers

Nature, 2018
External forces can make cells undergo large, irreversible deformations. It emerges that stretched mammalian cells grown in vitro can enter a state called superelasticity, in which large, reversible deformations occur. Mammalian cells can undergo large-scale, reversible deformations.

Micropolar elastic percolation: The superelastic problem

Physical Review B, 1988
This paper deals with the critical elastic behavior of a two-dimensional micropolar (or "granular") network with randomly rigid or elastic bonds. It presents a new derivation of Feng's inequalities $1l{s}^{\ensuremath{'}}ls$ in the context of micropolar elasticity (where $s$ is the conductivity exponent, ${s}^{\ensuremath{'}}$ the elastic-moduli ...

Superelasticity of CoNiGa:Fe single crystals

Applied Physics Letters, 2005
We have fabricated CoNiFeGa single crystals with excellent superelasticity. The superelastic strains of 4% and 6.7% in compression have been obtained along the [001] and [110] directions, respectively. These single crystals show strong anisotropy in strains, superelastic parameters, and even transformation path related to the different crystalline ...

Superelasticity in Shape-Memory Materials

2003
The recently developed crystal-mechanics-based constitutive model of Thamburaja and Anand [8] for superelasticity of shape-memory materials is reviewed and shown to quantitatively predict the superelastic response of an initially-textured Ti-Ni alloy in a variety of reasonably complex deformation modes.
