- Fig. 1 one of the options for an alternate installation made in the form of a closed inlet is supplied, which is completed in the form of a closed
- the ratio of the lengths of the ellipse's systems is 0.75, which is based on the results calculated above.
- the distance between the branches was spiraling at 1.5–2.5 mm.
- the magnitude of the pitch is not impaired by the rapid growth of the vein wall, by allowing it to be weakened between the twists.
- a smaller step size prevents rapid revolutions of the venous wall after its mobilization during the operation.
- a larger value of the step creates the possibility of reducing the venous wall between the veins and the increase in internal pressure.
- a well-known range of die diameters of 0.3–0.60 mm has been reduced, which makes it possible to ensure that the pressure is not subject to pressure.
- a cross-section of less than 0.3 mm does not require the required stability, and a cross-section of more than 0.6 mm is not wired.
- 5 Ends are spiraling made in the form of a loop closed circuit ;. a country lying in the area of the area forming the elliptical qilin of the river. This type of operation allows the circuit breaker to automatically install the installation.
- the material for the manufacture of the equipment will double the temperature of the mechanical processing on the surface.
- the effect of the overhaul ensures the restoration of the form of the operation after the significant significant deformation during its installation.
- the ends of the quasi-sinusoid are made in the form of a closed loop lying in the rotational part of the elliptical cylinder.
- a convenient version of the cable allows you to ensure the automatic operation of the installation and operation of the device.
- the plate is made from a biological and inert material - titanium nikelide, compatible with live tissue and having a memory and a flash. Its approximate thickness is 0.3-0, 6 mm, the width of the grooves (2), performed in the plate, is selected to be the same as the value of 3 (it is equal to a little more than 1, it is equal to the value of 1;
- the total elliptical cylinder is 0.5–1.5 mm, and the optimal ratio of the ellipse is 0.7–0.9.
- the chosen interval of the thickness of the plate 0.3-0, 6 mm is stipulated by the fact that in this range the stability of the equipment withstands the maximum pressure is ensured.

- the selected platform for transferring the plate (an increase in the plate occupied by the metal must be set to 0.3-0.7) due to the fact that on this site 11 Provides normal external external supply ;. With a decrease in the area occupied by the metal, less than 0.3, the share does not have sufficient stability, and with an increase of 5 square meters, the increase is not significant.
- the width of the gap in the plate was equal to the width of the switch and was 1.0-1.5 mm.
- a large step size does not suppress a rapid revolu- tion of the vein wall, 0 preventing it from retreating to the vein.
- the smaller value at a step prevents rapid revolutions of the vein wall, the larger - creates the possibility of a decrease in venous venous distraction.
- a normal external supply of veins is ensured.
- the value of the indirect light in the transforming part of the elliptical cylinder (1) is ensured, which is also equal to 0.5-1.
- the plates are zagruzhennymi, in order to ensure the automation of the wall of the vein when installing the card.
- the selected housing of the entire ellipse / transverse section of the Hellenic cylinder / compartment in the range of 0.7-0.9 is connected to the house.
- a decrease in the rate below 0.7 - ⁇ and 5 leads to transverse vein deformity, and an increase above 0.9 does not affect an adequate valve operation.
- the extra-vasal component made in the form of a simple electric non-permanently formed cylinder (1) uses the following method. Before being installed on a vein, the plastic is deformed in a quasi-free mode in a cooled (-10 ° C to + 20 ° C) environment. In this case, the patient is guarded by a vein.
- the enlargement was performed as follows: after isolation and visualization, the valve was enlarged in an enlarged femoral vein;
- the 15th thigh phlebography revealed the instability of the valve of the obstructive femoral vein (Fig. 4).
- a phlebectomy is given because of the extrusion of an extra-vasal region of the valve of the obstructive femoral vein by an elliptical spiral.
- the valve is ⁇ issued in the same way as described in Example 1.
- Example 35 stasal obstruction of the valve of the femoral vein, such as described in Example 1. With the closure of the valve, the valve is lively (Fig. 7). Improvement of the regional venous hemodynamics, which made it possible to achieve quick healing of the ulcer. 05/15/95 phlebotomy of varicose veins 14 on the grave. The patient was discharged in a satisfactory condition.
