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 endoprosthesis 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.
Claims34
An endoprosthesis comprising:
- at least one body part having an outer surface,
- wherein thrombogenic elements are arranged at least partially on the outer surface of the at least one body part of the endoprosthesis and, during use, the thrombogenic elements extend a distance away from the outer surface of said at least one body part, and
- the endoprosthesis is provided with at least one retaining means for retaining the thrombogenic elements near the surface of said at least one body part;
- wherein the at least one retaining means has first and second configurations and is changeable from the first to the second configuration, the at least one retaining means, when in the first configuration, maintains the thrombogenic elements adjacent to the outer surface of the endoprosthesis to assist with installation and implantation of the endoprosthesis, but when the at least one retaining means is changed to the second configuration, the thrombogenic elements are released and thus free to move away from the outer surface and promote thrombosis.
