Problems solved by technology

The "Y"-shaped stent technology can reshape the aneurysm neck, exert mechanical barriers, place coils to protrude into the parent artery, and can reduce the blood flow guide and promote the intima of the aneurysm neck through the stent. The possibility of aneurysm recurrence, but the "Y" type stent technique is complicated to operate, the operation process is complicated, and it is difficult to implement

Embodiment Construction

[0021] The core of the present invention is to provide a vascular stent, which simplifies the operation process, improves the success rate of the operation, and reduces the operation cost.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a specific embodiment of the vascular stent provided by the present invention.

[0024] The vascular stent provided by the specific embodiment of the present invention includes an elastic hollow sphere 1, which is provided with a hollow hole, and the elastic hollow sphere 1 can be compressed and elongated to move in the blood vessel, and the elastic hollow sphere 1 can move in the blood vessel. Expand into a sphere, so that the outside of the elastic hollow sphe...

Abstract

The invention discloses an intravascular stent. The intravascular stent comprises an elastic hollow sphere; hollow holes are formed in the elastic hollow sphere; the elastic hollow sphere can be compressed and stretched to move in a blood vessel, and the elastic hollow sphere can be unfolded to form a sphere in the blood vessel, so that the exterior of the elastic hollow sphere is tightly adhered and fixed to the inner wall of the blood vessel. No matter what position the intravascular stent is placed, the intravascular stent appears a uniform sphere after being unfolded, so that the intravascular stent can be released without being positioning deliberately; therefore, a surgical operation is facilitated; the surgery success rate is improved; the surgery cost is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a blood vessel stent. Background technique [0002] In many surgical procedures, it is necessary to place vascular stents in the blood vessels to support the corresponding components. For example, the operation for the treatment of basilar artery tip aneurysm is recognized as one of the refractory intracranial aneurysms. The aneurysm is located deep and close to the brain. The trunk and multiple groups of intracranial nerves make it difficult to expose the tumor by surgery, and the treatment risk is high. Interventional treatment such as bifurcation aneurysms in the brain is also difficult. For such bifurcation aneurysms, the traditional treatment is the "Y" stent technology assisted by coil embolization technology, which can protect the parent artery to the greatest extent and at the same time densely pack the aneurysm. The so-called "Y"-shaped stent technology is to first place ...
