Problems solved by technology

[0002] Cerebral angioplasty solves the problem of cerebrovascular stenosis very well, but the stent exists in the cerebrovascular for a long time, and there is a risk of further thrombosis and stenosis under the action of the immune system
Moreover, the stent exists as a foreign body for a long time, and the patient needs to use Canning drugs for a long time. The long-term psychological and physical discomfort of the patient causes great pressure to the patient.

Abstract

The invention belongs to the technical field of medical apparatuses, and in particular relates to a loop-type temporary cerebrovascular stent. The stent comprises a metal stent main body, a blood flow channel which is used for supporting a vascular wall and is capable of offering a hollow space for a blood flow, and a suture line which is fixedly arranged on the edge part of the metal stent main body. The loop-type temporary cerebrovascular stent provided by the invention, when applied to dilation therapy of cerebrovascular occlusion and stenosis, can effectively avoid a risk that vascular thrombosis or stenosis attacks once again; and by arranging the suture line on the edge part of the metal stent main body, the stent can be taken out conveniently after control and treatment of cerebrovascular stenosis.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a cerebrovascular loop-type temporary support. Background technique [0002] Cerebral angioplasty has solved the problem of cerebrovascular stenosis very well, but the stent exists in the cerebrovascular for a long time, and there is a risk of further thrombosis and stenosis under the action of the immune system. Moreover, the stent exists as a foreign body for a long time, and the patient needs to take Canning medicine for a long time. The patient feels a lot of psychological and physical discomfort for a long time, which causes great pressure to the patient. [0003] With the use of the loop-type stent, when the cerebrovascular stenosis is controlled and treated clinically, the doctor can easily take the stent out of the body with a recovery catheter, thereby avoiding the occurrence of the above side effects. Contents of the invention [0004] In order to solve the a...
