Abstract

1. Стент, предотвращающий собственную миграцию, содержащий:полое цилиндрическое тело, изготовленное из металлической проволоки;первые блокирующие части, выступающие наружу из тела; ивторые блокирующие части, сформированные на расстоянии от первых блокирующих частей в продольном направлении тела в симметричном отношении по отношению к первым блокирующим частям вокруг вертикальной поверхности по отношению к продольному направлению тела.2. Стент по п.1, в котором сформировано множество, по меньшей мере, одних из первых блокирующих частей и вторых блокирующих частей.3. Стент по п.2, в котором, по меньшей мере, одни из первых блокирующих частей и вторых блокирующих частей расположены на одинаковом расстоянии друг от друга вдоль внешней периферийной поверхности тела для образования ряда, и, по меньшей мере, один или более рядов сформированы вдоль продольного направления тела.4. Стент по п.3, в котором первые блокирующие части и вторые блокирующие части сформированы с наклоном по отношению к внешней периферийной поверхности тела.5. Стент по п.4, в котором, по меньшей мере, одни из первых блокирующих частей и вторых блокирующих частей продолжаются от участка металлической проволоки, образующей тело, или выступают от внешней периферии тела отдельной металлической проволокой.6. Устройство для изготовления стента, предотвращающего собственную миграцию, содержащее:зажимную часть, имеющую цилиндрическое тело, подготовленное для изготовления стента, и, по меньшей мере, одно или более крепежных углублений, сформированных на внешней периферийной поверхности тела;опорные пальцы, выполненные с возможностью вставки в крепеж�1. A stent that prevents its own migration, comprising: a hollow cylindrical body made of metal wire, the first blocking parts protruding outward from the body; and second blocking parts formed at a distance from the first blocking parts in the longitudinal direction of the body in a symmetrical manner with respect to the first blocking parts around a vertical surface with respect to the longitudinal direction of the body. 2. A stent according to claim 1, wherein a plurality of at least one of the first blocking parts and the second blocking parts are formed. The stent according to claim 2, in which at least one of the first blocking parts and the second blocking parts are located at the same distance from each other along the outer peripheral surface of the body to form a row, and at least one or more rows are formed along longitudinal direction of the body. 4. The stent according to claim 3, in which the first blocking parts and the second blocking parts are formed with an inclination with respect to the outer peripheral surface of the body. The stent according to claim 4, in which at least one of the first blocking parts and the second blocking parts extend from a portion of the metal wire forming the body, or protrude from the outer periphery of the body by a separate metal wire. A device for manufacturing a stent that prevents its own migration, comprising: a clamping part having a cylindrical body prepared for the manufacture of a stent, and at least one or more mounting recesses formed on the outer peripheral surface of the body; supporting fingers configured to be inserted into fasteners�

Claims

1. A stent that prevents its own migration, containing:

a hollow cylindrical body made of metal wire;

first blocking parts protruding outward from the body; and

second blocking parts formed at a distance from the first blocking parts in the longitudinal direction of the body in a symmetrical manner with respect to the first blocking parts around a vertical surface with respect to the longitudinal direction of the body.

2. The stent according to claim 1, in which a plurality of at least one of the first blocking parts and the second blocking parts are formed.

3. The stent according to claim 2, in which at least one of the first blocking parts and the second blocking parts are located at the same distance from each other along the outer peripheral surface of the body to form a row, and at least one or more rows formed along the longitudinal direction of the body.

4. The stent according to claim 3, in which the first blocking parts and the second blocking parts are formed with an inclination with respect to the outer peripheral surface of the body.

5. The stent according to claim 4, in which at least one of the first blocking parts and the second blocking parts extend from a portion of the metal wire forming the body, or protrude from the outer periphery of the body by a separate metal wire.

6. A device for the manufacture of a stent that prevents its own migration, containing:

a clamping part having a cylindrical body prepared for the manufacture of the stent, and at least one or more mounting recesses formed on the outer peripheral surface of the body;

supporting fingers configured to be inserted into the mounting recesses to support the metal wire forming the stent so that the metal wire bends in a zigzag configuration on the surface of the clamping part; and

fixing parts forming fingers, each of which has an insertion hole formed in its inner part so as to insert a corresponding support finger into it, and fixing recesses made along its outer peripheral surface.

7. The device according to claim 6, in which the fixing parts forming the fingers have an inner diameter larger than the outer diameters of the supporting fingers so that the fixing parts forming the fingers are connected to the supporting fingers.

8. The device according to claim 7, in which at least one or more of the locking recesses are formed along the outer peripheral surface of each locking part forming a finger in the longitudinal direction of each fixing part forming a finger.

9. The device of claim 6, in which the locking fingers and the locking parts forming the fingers are made integrally with each other.

10. A device for the manufacture of a stent that prevents its own migration, containing:

a clamping part having a cylindrical body prepared for the manufacture of the stent and at least one or more mounting recesses formed on the outer peripheral surface of the body; and

locking fingers configured to be inserted into the mounting recesses so as to protrude from the outer peripheral surface of the clamping part, and having recesses formed along their outer peripheral surfaces.

11. A method of manufacturing a stent that prevents its own migration, which includes stages in which:

connecting the stent with a clamping part having a cylindrical body;

inserting the locking fingers into at least one or more mounting recesses formed on the outer peripheral surface of the clamping part;

connecting the fixing parts forming the fingers, each of which has a recess formed along its outer peripheral surface with the locking fingers;

attach the metal wire to one side and to the other side of the stent so that it protrudes outward from the stent, thereby forming the first blocking parts, and rigidly block the first blocking parts in the recesses formed around the fixing parts forming the fingers; and

the second blocking parts are formed symmetrically with respect to the first blocking parts around a vertical surface with respect to the longitudinal direction of the stent.

12. The method according to claim 11, in which at least one of the first blocking parts and the second blocking parts extend from a portion of the metal wire forming the body, or protrude from the outer periphery of the body in the form of a separate metal wire.
