Problems solved by technology

Since the supporting force of the biodegradable self-expanding stent becomes weaker when the diameter is larger, the prospect of applying it to the treatment of stenotic lesions of large and medium arteries is very slim

Embodiment 1

[0076] Such as Figure 1 to Figure 5 The net-covered stent shown includes a self-expanding stent and a net-cover 3 , the net-cover 3 includes a ring body 31 and a net body 32 , and the proximal side of the net-cover 3 is connected with a mesh cable 4 . A covering mesh 3 is arranged outside the known self-expanding stent to constitute the main body of the system; the distal end of the covering mesh 3 forms a multi-point fixed connection with the self-expanding stent, and its connection point can be located on the self-expanding stent. Any position between the middle section of the expandable stent and the distal end; the cover mesh 3 forms a multi-point flexible connection with the proximal side of the self-expandable stent. The net rope 4 is used in cooperation with the taking-out tool when taking out the net-covering support. When the self-expanding stent is in an expanded state and fixed in the blood vessel lumen, when the mesh cable 4 is pulled by the pulling tool, the cov...

Embodiment 2

[0088] A mesh-covered stent, the rest of which are the same as in Embodiment 1, and a fusion layer is provided between the mesh body 32 and the self-expanding stent. Before the mesh body is stressed, the mesh body and the self-expanding stent form an integrated structure through the fusion layer. When the mesh body is stressed, the fusion layer breaks.

Embodiment 3

[0090] Such as Figure 6 ~ Figure 9 The net-covered stent shown includes a self-expanding stent and a net-cover 3 , the net-cover 3 includes a ring body 31 and a net body 32 , and the proximal side of the net-cover 3 is connected with a mesh cable 4 .

[0091] The self-expanding stent is a corrugated self-expanding stent 1, which includes a plurality of corrugated support rings and bridges 12, and adjacent corrugated support rings are connected through the bridges 12;

[0092] The wave-shaped support ring is provided with a limit hole 101 at its peak, and the axially adjacent peak point of the wave-shaped support ring is parallel to the axial centerline of the wave-shaped self-expanding stent 1;

[0093] The mesh body 32 of the covering mesh 3 is a tubular structure composed of mesh body mesh units and woven by a plurality of mesh wires 321, and the diagonal line of each mesh body mesh unit is in line with the wave The axial center line of the type self-expanding stent 1 is p...

Abstract

The invention relates to the technical field of medical devices, in particular to a mesh-covered stent, including a self-expandable stent and a mesh-covering, and the mesh-covering includes a ring body and a mesh body, wherein the ring body and the proximal center of the self-expandable stent The side is movably connected, and the distal end of the mesh body is fixedly connected with the self-expanding stent; the proximal side of the covered mesh is connected with a mesh cable. The beneficial effect of the present invention is to provide a mesh-covered stent device that can not only be implanted into the arterial blood vessel but also be removed from the arterial blood vessel after a period of time when treating arterial stenosis clinically, reducing even The adverse effect caused by long-term storage in the body of the existing self-expanding stent is eliminated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mesh-covered stent, which can not only be implanted into the arterial blood vessel, but also be taken out from the arterial blood vessel after a period of time for the clinical treatment of arterial stenosis. Background technique [0002] The self-expanding stent is a currently known device suitable for the treatment of large and medium arterial stenosis. The stent delivery catheter loaded with the self-expandable stent is sent to the arterial stenosis through the peripheral artery, and then the self-expandable stent is pushed out from the stent delivery catheter, and the self-expandable stent expands by itself and supports the arterial lesion. [0003] The main function of the self-expandable stent is to provide support for the pre-expanded arterial wall, keep the blood vessel in an expanded state, and prevent blood vessel collapse and occlusion. Necessary in arterial...
