Abstract
Abstract An endoprosthesis includes an extensible tubular mesh embedded in a plastic or elastomer extensible film. A tool for positioning the endoprosthesis includes a tube-shaped guide provided at its distal end with a tulip-shaped housing. Cutting threads cause the housing to open longitudinally into several petal-like parts. Application is to endoluminal treatment of aneurisms and dilations.
