Abstract

The invention relates to a hemangioma plugging device, a hemangioma plugging treatment device and a hemangioma plugging system.The hemangioma plugging device comprises a net-shaped expansion structure and a guiding structure, and the net-shaped expansion structure has an unfolded state in which the net-shaped expansion structure is wound into a spiral shape from the far end to the near end and a compressed state in which the net-shaped expansion structure is delivered to hemangioma from the inside of a blood vessel; at least one part of the guide structure is arranged in an inner cavity of the net-shaped expansion structure, and when the net-shaped expansion structure is in a spiral shape, at least one part of the guide structure is unfolded in the inner cavity of the net-shaped expansion structure to be in a spiral shape. According to the invention, stable and compliant filling is realized, and the method also has the advantages of preventing hemangioma rupture, preventing vascular embolism, improving the coverage rate of a tumor neck opening, promoting the formation of thrombus in a tumor, accelerating hemangioma embolism and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hemangioma blocking device, a hemangioma blocking treatment device and a hemangioma blocking system. Background technique [0002] Intracranial aneurysm is a pathological protrusion of the intracranial artery wall, with an incidence rate of 5% to 10%. MRA research shows that the incidence rate of unruptured aneurysm in Chinese adults aged 35 to 75 is about 7.0%. Although subarachnoid hemorrhage caused by intracranial aneurysm rupture accounts for about 5% of strokes, the mortality rate for the first rupture is 20% to 30%, and the mortality rate for the second rupture is as high as 60%. The root of the treatment of aneurysms is to completely isolate the aneurysm from blood circulation through therapeutic means. Current treatment methods mainly include craniotomy and clipping therapy and endovascular interventional therapy. Among them, endovascular interventional therap...
