(54) FOOD ENDOPROTESIS

(57) The invention relates to medical technology, namely to devices for clamping blood vessels. The purpose of the invention

is to reduce the likelihood of scarring by reducing the morbidity of the endoprosthesis. The esophageal endoprosthesis comprises a body made in the form of an elastic cavity 1, with a notch 2, air ducts 3 and 4. An elastic ring 5, a removable fixing element in the form of a ligature 7. An endoprosthesis is inserted through the mouth into the desired esophagus, or through air ducts 3 and 4 (or any moving mixture, such as water, etc.) is pumped into cavity 1. Due to the coaxial installation inside cavity 1, at an equal distance from its ends of the elastic ring 5, the cavity symmetrically from it assumes a convex-concave shape. Next, in the recess 2, a fixing element in the form of a ligature 7 is installed, which presses the wall of the esophagus to the body of the prosthesis 1 sludge.

ABOUT

H)

The invention relates to medical technology, in particular to devices dp clamping blood vessels.

The aim of the invention is to reduce the likelihood of the development of the scar structure by decreasing the trap volume of the endoprosthesis unit.

The drawing shows the esophageal endoprosthesis, incision,

The endoprosthesis comprises a body made in the form of an elastic closed cavity 1, with a notch 2 on the outer surface and an air duct in the form of two tubes 3 and 4, an elastic ring 5, a centering sleeve B and a removable fixing element in the form of a ligature 7.

The endoprosthesis works as follows

Claims (1)

Through the mouth with the help of an endoscope, the necessary digestion is reduced by B, through ducts 3 and 4 with the help of air (or any moving mixture, for example glycerol, water, etc.), the outer diameter of the endoprosthesis is gradually increased to the required dimensions ( in each case individually) so as to slightly expand the wall of the esophagus. The installation site of the endoprosthesis and its dimensions are controlled by probing the latter through the wall of the esophagus. Due to the coaxial installation inside cavity 1, at an equal distance from its ends of the elastic ring 5, the cavity symmetrically assumes a convex-concave shape from it. Next, in the recess 2, a fixing element is installed in the form of a ligature, which presses the wall of the esophagus to the body of the endoprosthesis. Claims Esophageal endoprosthesis, comprising a cylinder-shaped body with a notch on the outer surface, made at equal distance from its ends, a centering sleeve installed in the body, and a removable locking element installed in the cavity, characterized by the fact that in order to reduce the likelihood of the development of the scar structure by reducing the traumatic process of installing the endoprosthesis, the body is made in a flexible closed zid cavity with a duct in the form of two tubes mounted on the same elasse This ring is attached to the outer wall inside the cavity at an equal distance from its ends.
