Abstract

The invention provides a support. The support comprises a support body and at least one identification mark arranged on the support body. Wherein the stent body is tubular and is provided with two opposite ends and a middle area connected between the two ends, and at least one identification mark is arranged on the middle area. Therefore, in the stent provided by the invention, at least one identification mark is arranged in the middle area, so that the problem that the release amount cannot be determined due to the fact that the identification marks are arranged at the two ends of the stent body is solved. Besides, at least one identification mark arranged in the middle area is convenient for a doctor to clearly judge the release amount of the stent and determine the placement position of the stent in an operation, so that the stent can be placed in a better position.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent. Background technique [0002] Cerebrovascular disease refers to various diseases of the blood vessels in the brain, including cerebral atherosclerosis, stenosis, occlusion, cerebral aneurysm, intracranial vascular malformation, cerebral arteriovenous fistula, etc. The common feature is the ischemia of the brain tissue. Or hemorrhagic accident, resulting in disability or death of the patient. At present, interventional therapy can cure many diseases that are difficult to treat clinically. For example, intracranial aneurysms, arteriovenous malformations, etc. Usually, for patients with cerebrovascular disease, interventional therapy refers to the diagnosis and treatment of cerebrovascular disease using endovascular interventional technology under the monitoring and guidance of medical imaging. The stent implantation is completed by catheter digital subtraction, ...
