Description

A stent having a connector having a plurality of bent portions formed therein,

The present invention relates to a stent, and more particularly, to a stent having an irregular structure so that it can be twisted transversely as well as refracted. Therefore, the stent can be easily inserted into a body tube such as a blood vessel or a water tube, It is possible to prevent damage to the pipe, to maintain the expanded or open state, to increase the amount of deformation upon bending by being bent many times, to increase the application amount of the chemical solution by increasing the area, To a stent having a connector with a plurality of bent portions formed therein.

Generally, a stent is a tubular structure that is implanted in the body's conduits, blood vessels, or other body tubes to help expand or open such tubing.

Typically, the stent is delivered into the body in a compressed configuration and then once positioned at the target location within the tube to expand to its final diameter.

The stent is often used or replaced to prevent balloon angioplasty and future stenosis recurrence to treat stenosis, and more commonly, it is used in vessels, gallbladder, stomach, respiratory and other organs, It is being used to treat many body tubes like the same.

In one embodiment of such a conventional stent, a plurality of members are formed to have a serpentine pattern, as disclosed in Patent No. 10309485, which member is configured to interconnect with other adjacent patterns.

This is as shown in Fig. 1. When the stent 1 is used, the same binding force acts in the longitudinal direction and the circumferential direction.

However, as shown in Fig. 2, the stent 1 can be simply bent in any direction, but when the blood vessel 2 is warped in the transverse direction, the stent 1 can not be deformed transversely due to the same binding force .

As described above, if the transverse distortion of the blood vessel 2 is not accommodated, a problem may occur that the blood vessel 2 is damaged by the installed stent 1, which may worsen the situation.

Accordingly, there is an urgent need to develop a stent which can easily cope with warping in a transverse direction as well as being bent in any direction so that it can be easily dealt with deformation of a blood vessel.

A stent 10 having a connector having a plurality of bent portions formed therein is installed so as to expand or narrow the narrowed body tube.

The stent 10 is inserted into a body tube in a state where the stent 10 is curled to the outside of an insertion tube (not shown), and then the body tube is expanded as the body is expanded outward.

Of course, the insertion tube provided with the stent 10 is retracted again and then disengaged from the body tube.

As shown in FIGS. 3 to 4, when the stent 10 is viewed flat, a plurality of cell units are formed in the longitudinal direction, and each cell unit is divided into a plurality of cells 100 in the width direction And a node 400 connecting the plurality of cells 100.

Here, the longitudinal direction is defined as the longitudinal direction of the tubularly-shaped stent 10, and the transverse direction is defined as the transverse direction of the expanded circumferential direction of the stent.
