Abstract
The compression anastomosis clip (CAC) is an elliptic shape double-ring device produced from nickeltitanium shape memory alloy. Until now the CAC works basing on the one-way shape memory effect. The aim of presenting studies was finding out the technology of two-way shape memory (TWSME) clips formation which should fulfil the requirements for clinical application. The clips were formed by wires of an alloy with 51.02 at. % Ni – balance Ti. The best value of the TWME and uniform compression force of the clips was achieved by combining deformation, constrained aging and thermomechanical cycling.
