Abstract

The invention provides a medical implant and a medical device. The medical device comprises the medical implant, and the medical implant comprises a plugging part and a thrombosis promoting coating; the plugging part is of a curved surface structure and is used for being arranged at an opening of a target object. The plugging part comprises a supporting body and a covering film attached to the supporting body, and the thrombosis promoting coating is formed on at least partial area of the surface, closest to the inner cavity of the target object, of the covering film. For example, if the target object is an aneurysm, when the medical implant is arranged at the neck opening of the aneurysm, the thrombosis promoting coating is arranged towards the aneurysm cavity, thrombosis of the aneurysm can be promoted, the aneurysm cavity does not need to be filled with an embolism spring ring, and the risk that the embolism spring ring falls off to cause thrombus is avoided; and regrowth of the aneurysm is not caused.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to medical implants and medical devices. Background technique [0002] The incidence rate of intracranial aneurysm in the general population is 3% to 5%, and the annual probability of aneurysm rupture is about 0.95%. Once an aneurysm ruptures, the fatality rate is as high as 40%. Brain injury due to aneurysm can change the life style of patients and their caregivers, and its loss of quality of life and direct treatment costs impose a huge burden on society and the medical system. [0003] The traditional treatment of intracranial aneurysms is open surgery, which involves craniotomy, is extremely invasive, has high technical requirements, high mortality, and long postoperative recovery time. In recent years, vascular interventional surgery has been applied to the treatment of intracranial aneurysms. By introducing embolic coils, the embolic coils are used to fill the aneurys...
