Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "distal" and "proximal" in the context of the present invention should be understood as viewed from the direction of the attending physician. Distal is the side away from the attending physician, while proximal means towards the attending physician. If the phrase "axial direction" is used in this document, it should be understood to mean the direction in which the device of the present invention is propelled, and the direction perpendicular to the axial direction is defined as "radial". Describes, but does not indicate or imply that the device or element referred to must have a spec...

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a novel cerebral thrombus removal device and a method for removing a thrombus by using the device. The cerebral thrombus removal device includes a stent and a transportation system connected with the near end of the stent, the stent is of a self-expansion pipe network structure formed through mutualconnection of multiple mesh units, the surface of the stent is curved in a wave shape, the stent is transported to the vascular embolism position of an intracranial great vessel through the transportation system, the stent of the pipe network structure is unfolded through self-expansion, and the thrombus is captured. The surface of the stent is arranged to be curved in a wave shape, so that the contact area of the surface of the stent and a vessel wall is small, the metal coverage is low, in the process of thrombus removal, damage to the intima of the vessel is less, friction between the thrombus and the vessel wall is reduced at the same time, and therefore the thrombus is easy to remove and maintained to be relatively integrated to prevent thrombus debris from entering the far end or anormal vessel; the thrombus can be removed fast, and the stability of thrombus removal is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel device for removing a cerebral thrombus and a method for removing a thrombus using the device. Background technique [0002] At present, China is a major stroke country in the world, and stroke has become the first cause of death among Chinese residents. According to relevant foreign epidemiological studies, 3 out of every 4 stroke patients suffer from different degrees of disability. [0003] Acute ischemic stroke (acute ischemic stroke, AIS, commonly known as cerebral infarction) is the most common type of stroke, accounting for 80% of all strokes, especially acute stroke caused by large vessel occlusion, which is often dangerous, with mortality and disability. The high rate will cause the greatest harm to the patient. Once a stroke occurs, it will cause a heavy burden to the patient himself, his family and the society. [0004] Time is life, ultra-early thro...
