Abstract

The invention relates to an embolism protection device. The embolism protection device comprises a conveying guide wire and a filter screen. The filter screen is arranged on the conveying guide wire and comprises a mesh basket formed by weaving metal wires, the mesh basket comprises a near-end section, a far-end section and a middle section connected with the near-end section and the far-end section, the near-end section is of an opening structure, the far-end section is of a closing structure, the middle section is of a cylindrical structure, the near-end section and the far-end section are connected with the conveying guide wire, a projection of the mesh basket on a plane perpendicular to the extending direction of the conveying guide wire comprises a first inclined edge, a first connecting edge, a second inclined edge and a second connecting edge which are connected in sequence, the first connecting edge is parallel to the second connecting edge, and the length of the first connecting edge is 1 / 4-1 / 3 of that of the second connecting edge. The contact area of the embolism protection device and the blood vessel wall is relatively large, so that the risk of displacement under bloodflow is reduced, and the possibility of embolus leakage is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an embolism protection device. Background technique [0002] What is presented in this section is background information related to the disclosure of the present application only and is not necessarily prior art. [0003] At present, cardiovascular and cerebrovascular interventional treatment methods, such as balloon dilation, atherectomy of vascular plaques, stent expansion, valve surgery, etc., are prone to emboli during the operation. These emboli are lumps within blood vessels that travel along the direction of blood flow into narrowed vessels and can cause blockage of blood vessels in distal parts of the body, such as in valve repair or replacement surgery where manipulation of a calcified valve can result in calcified material Calcified material, tissue particles, and other debris move, and calcified material, tissue particles, and other debris may form a mass,...
