BIOCOMPATIBLE ENDOPROSTHESES

摘要

The vascular endoprosthesis comprises an array of cylindrical elements (4) arranged internally or externally and secured (8) to a continuous tubular element (7). This composite device is described as an arrayed stent graft. The cylindrical elements of the arrayed stent graft are constructed of metal or other suitable material, and the tubular element may be either knitted or woven textile, a thin walled polymer tube, a thin walled elastomeric tube or a composite of two or more of these or other compounds. All external surfaces of the arrayed stent graft are composed of biocompatible material consisting of a polymer having both non-thrombogenic and anti-thrombogenic properties on the same polymer backbone or, if required, only non-thrombogenic or only anti-thrombogenic properties as described in WO 97/41164.
