Intravascular implanted device bag and preparation method for implanted device

Abstract

The invention relates to the field of medical instruments, in particular to an intravascular implanted device bag and a preparation method for an implanted device. The implanted device is an intravascular stent which is locally wrapped by a film, and can be implanted in a blood vessel to treat vascular diseases such as aneurysm, particularly intracranial aneurysm. The implanted device bag comprises a film material to be coated and a mesh stent, wherein a main ingredient of the film material is alkylcyanoacrylate. By using the preparation method provided by the invention, the implanted device is directly filmed on a tumor neck on site; the preparation method can be used for accurately and quickly closing the tumor neck; a branch can be kept open; a space occupying effect can be obviously improved; and thus, true cure of the aneurysm is realized.

Description

technical field [0001] The invention relates to the field of medical instruments. More specifically, the present invention relates to an intravascular implantation device package and a method of manufacturing the implantation device. The device can be used for implanting blood vessels to treat vascular malformations, such as aneurysms, etc., especially intracranial aneurysms. Background technique [0002] The vessel wall, especially the arterial vessel wall, may undergo local abnormalities under the action of internal and external factors such as mechanical injury, vascular sclerosis, hypertension, proliferation of vascular smooth muscle cells, bacterial or viral infection, induction of venous valve disease, and blood flow impact A dilation or bulge is called an aneurysm. Aneurysms can occur in different parts of the body, most commonly abdominal aortic aneurysms and intracranial aneurysms. Intracranial aneurysm is a cystic expansion of the intracranial blood vessel wall....

AI Technical Summary

Problems solved by technology

The results show that the proximal end is completely cured, while the distal end is closed, and the treatment of aneurysms needs further study

In addition, the local covered stent has defects such as inaccurate positioning and difficulty in achieving three-dimensional rotation of the microcatheter inside.
