Embodiment Construction

[0018] The best mode of implementation of the present invention

[0019] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] As shown in Figure 2, the artificial vascular stent of the present invention comprises:

[0021] The artificial blood vessel main body 1 is sufficiently flexible to be bent in any direction, and the artificial blood vessel main body 1 has a structure in which an upper end portion thereof is formed in a single cylindrical shape or a partial cylindrical shape, and a lower end portion thereof is divided into sections of different lengths. Two small cylinders or parts of cylinders to enable insertion into the blood vessel and prevent intravascular pressure from being applied to the weakened vessel wall;

[0022] A cylindrical first stent component 2, the first stent component 2 is connected to the upper end of the main body of the artificial blood vessel to support the main b...

Abstract

The present invention discloses an artificial blood vessel stent, which can minimize the diameter of a stent insertion device because the diameter (profile) thereof is uniform and small over the entire length upon being loaded, and accordingly can be easily placed in a branched portion of a blood vessel using a puncture method. The artificial blood vessel stent comprises: (I) an artificial blood vessel body 1 in which the upper end part is formed with a single cylindrical shape or partially cylindrical shape and the lower end part is divided into two small cylindrical shapes or partially cylindrical shapes having different lengths; (II) a cylindrical first stent member 2 connected to the upper end of the artificial blood vessel body and being expandable; (III) a cylindrical second stent member 3 connected to the shorter side of the lower end part of the artificial blood vessel body and being expandable; and (IV) a cylindrical third stent member 4 inserted into the longer side of the lower end part of the artificial blood vessel body, so that the upper end surface coincides with the lower end surface of the second stent member, and being expandable.

Description

technical field [0001] The present invention relates to an artificial blood vessel stent, and, more particularly, to an artificial blood vessel stent whose diameter (shape) is within It is uniform and small over its entire length, so it can minimize the diameter of the stent insertion device (hereinafter referred to as "cannulation device"), and thus it is possible to easily place this artificial vascular stent using a puncture method such as A branch of a blood vessel such as an artery. [0002] An aneurysm as an example is characterized by dilation of an artery in a manner similar to that of a balloon, and an aneurysm is a very serious condition because if the pressure inside the blood vessel increases above a certain level, it weakens The arterial wall may rupture. Background technique [0003] Artificial vascular stents have been developed as a treatment for aneurysms, which can solve the problems associated with aneurysms through surgery and minimize the patient's pai...
