Description

"

The invention relates to medicine and can be used for intravascular surgery.

The purpose of the invention is to accelerate the formation of neointima and the creation of uniform pressure on the surface of the vessel.

FIG. 1 shows the intravascular framework in a free state mounted on the end of the conductor; Fig. 2 shows the intravascular framework at the time of passage through the catheter; in Fig, 3 - the intracavitary framework installed in the vessel,

The intravascular framework is a wire rod) {sinu 1 of an alloy that has a shape memory effect, coated with silicone with an outer diameter D, a wire diameter d and a step of turns t. The diameter of the spring D, taking into account the properties of the alloy and the walls of the vessel, is 1.05-1.15 of the internal diameter of the vessel D, With a ratio D / D (less than 1.05 the inside of the vessel is unstable with respect to the longitudinal smidge in the vessel under the action of blood flow. With a D / D ratio of more than 1.5, the carcass pressure exceeds the resistance of the vessel walls, which leads to excessive expansion of the vessel section. The wire diameter d can vary between 0.004 and 0.15 of the spring diameter, which is determined based on the volume memory material, with respect to less than 0,004 spring is not develops products that are sufficient to counteract the walls of the vessel. At a ratio of more than 0.15, the spring incompletely restores the original shape in the vessel.

The springs are between 0.1 and 0.5 times the diameter of the spring, which contributes to the accelerated ion exchange and the formation of neointima on the inner surface of the frame. With a ratio of less than 0.1, the coils of the spring fit snugly together and make ion exchange difficult, and with a ratio of more than 0.5, the distance between the coils becomes sufficient

0 to partially sag the vessel walls, resulting in partial stenosis,

DL of the carcass under local anesthesia is performed percutaneously.

 5, puncture of the femoral artery according to the Seldinger method and inserted into the vessel of the x-ray contrast catheter 2, the skeleton is fixed on, conductor 3, cooled with chlore to a temperature below

20 and introduced through the catheter 2 into the vessel 4 to the place of the required installation, then the catheter is retracted until the rear end of the frame is released. As a result of the influence of the heat of the blood, the wire of the skeleton recalls the shape of the spring that was predetermined to it, creating a uniform resistance to it, its pressure on the vessel wall and preventing its narrowing. Silicone coating

30 of the framework prevents thrombosis and promotes the rapid formation of neointima on the inner surface of the framework.

jt; Thus, the proposed design of the intravascular framework allows vessels of various sizes to expand without causing thrombus formation 5 and to create uniform pressure on the inner surfaces of blood vessels.
