Definitions

  • the area of technology is related to medicine, more precisely - to a cardiopathy, and specifically - to the heart valve,
  • valve ring or cabinet with accessory for installation a mounted disk for installing or closing and processing is installed.
  • This disk is installed in a floating state with the upper and lower operating parts or so-called
  • valves have a fixed access to services, including, for example, to ensure that they are free from a large volume of disks.
  • this type of heart valve has a rather massive disk due to the fact that it is distal
  • the task is to perform a heart disks in order to reduce its weight, in order to ensure that the condition of the car is improved - 2 -
  • the operation of the valve, and so the conditions for the rehabilitation of the patient are • improved.
  • the posed problem is solved in that, in the form of a valve of the heart, which contains the valve ring with the answer for
  • One of the variants of the invention is that there is a separate section of the remote access and the maximum condition of the room is the same. In this case, the best hemodynamic conditions are ensured for the flow in the circle of the valve.
  • FIG. 1 is a view, in part, partially of the nature, of a heart-shaped valve, in accordance with the latest embodiment of the invention
  • Fig. 2 is a partial view of a section of a panel disc for fig.
  • the proposed valve is manufactured from biologically inert materials, such as titanium alloys or carbonaceous materials.
