abstract the invention relates to an endoprosthesis (1), in particular a vascular or cardiac endoprosthesis (1), having a body (2) and also one or more thrombogenic elements (3) that are fixed to the endoprosthesis (1) and that are able to extend a distance away from the body outside the latter. the endoprothesis comprises means (33) for selectively retaining the thrombogenic elements near the body (2). the release of the one or more thrombogenic elements, after the endoprosthesis has been fitted in place by a conventional method via a sheath, promotes thrombosis. *********************** Translation of the abstract patent summary: "endoprosthesis and delivery device for implanting such an endoprosthesis". the invention relates to a stent graft (1), in particular a vascular or cardiac stent graft (1), which has a body (2) and also one or more thrombogenic elements (3) which are attached to the stent graft (1) and which are capable of extending a distance in the opposite direction of the body out of the latter. The stent graft comprises means (33) for selectively retaining thrombogenic elements near the body (2). release of one or more thrombogenic elements after the stent graft has been snapped into place by a conventional sheathed method promotes thrombosis. 23226032v1 1/1 23226032v1abstract the invention relates to an endoprosthesis (1), in particular a vascular or cardiac endoprosthesis (1), having a body (2) and also one or more thrombogenic elements (3) that are fixed to the endoprosthesis (1) and that are able to extend a distance away from the body outside the latter. the endoprothesis comprises means (33) for selectively retaining the thrombogenic elements near the body (2). the release of the one or more thrombogenic elements, after the endoprosthesis has been fitted in place by a conventional method via a sheath, promotes thrombosis. *********************** tradução do resumo resumo patente de invenção: "endroprótese e dispositivo de aplicação para implanta
