Cyclic deformation of Ti-Ni alloy used for endovascular device

Abstract

Has been studied the possibility of using TiNi alloys with shape memory and pseudoelasticity as an implantation material for correction of functional mitral regurgitation endovascular device. The modes the deformation cycling were developed that allows fulfilness of necessary properties eligible to operate power-unit device for trans-skin implantation method. Preliminary deformation cycling provides mechanical properties range stabilization that guarantees the shape reinstatement of implant after its installation.
