COATED ENDOLUMINAL IMPLANT

摘要

A stent structure (30) particularly for use in treating cerebral aneurysms is provided with a fibrous coating (34) which reduces the permeability of the underlying stent (32) to an extent that the flow through the stent structure is sufficiently suppressed to allow for resorbtion of an aneurysm while still providing sufficient flow through the stent structure to allow for flow into the perforator vessels. The fibrous coating may have different permeabilities in different zones of the underlying stent (32). The coating could be applied to other devices such as filters and occluders.
