DEVICES AND METHODS FOR TREATMENT OF VASCULAR ANEURYSMS

摘要

Devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms (3) found in blood vessels are disclosed. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure (1) and the other part is an expandable tubular mesh structure (2), is provided. In the first embodiment, the expandable sponge structure (1) is intended to fill the aneurysm cavity (3) to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure (2) is placed across the aneurysm (3), contacting the inner wall of healthy vessel proximal and distal to the aneurysm (3).
