An adaptive aneurysm flow disturbance device and aneurysm treatment system
By designing an adaptive aneurysm disturbance device, the sliding connection between the first and second components and the retractable components are used to solve the problem that existing devices cannot adapt to the size of the aneurysm neck, achieving stable support and rapid thrombus formation, and preventing dislodgement and displacement.

Abstract
This invention discloses an adaptive aneurysm disturbance device and an aneurysm treatment system. The disturbance device includes: a first component having a self-expanding first expansion configuration, which provides a first radial support force when constrained; a second component having a self-expanding second expansion configuration, which seals the neck of the aneurysm; the first component and the second component are slidably connected, and the first and second components slide relative to each other when the aneurysm deforms to follow the volume change of the aneurysm; and / or the second component is sleeved around the first component, and the second component provides radial force through the first component when the aneurysm deforms to follow the volume change of the aneurysm. In this invention, when the aneurysm increases in volume due to blood flow pressure, the first and second components slide, and / or under the action of the radial force of the first component, the volume of the disturbance device also increases with the volume of the aneurysm, thereby forming an adaptive shape change.
