Abstract
The aortic-coronary shunting procedure developed by Dr. M. V. Suturin with the aid of a unique stapler designed by the company Endogene makes it possible to reconnect blood vessels with staples made of a superelastic Ti‐Ni alloy while the heart is still working (without its stoppage). The use of proprietary methods for post-deformation annealing of the wire used to make the staples makes it possible to obtain the best possible functional properties. The difference between the dislocation- and phase-based yield points is Δσ = 900 MPa. The average critical stress associated with superelastic recovery is 1.5‐2 times greater after low-temperature thermomechanical treatment than after warm drawing. Fully reversible deformation reaches a maximum of P r1 = 6.5%, while the maximum force obtained with the staples is P r se = 6.5 N. The high functionality of the staples is proven by the fact that they recover more than 90% of their initial shape. Storage of the staples in the
