A device for denuding the endothelium of a vascular cavity wall in order to maximize thrombosis and prevent recanalization in the vascular cavity. The device comprises an endovascular tool, such as a guidewire, microcatheter, microballoon or coil, and at least one denuding element attached to the endovascular tool, adapted to remove at least part of the endothelium of the vascular cavity wall while avoiding wall perforation. This invention also includes a method of preparing a vascular cavity having blood therein before vascular cavity occlusion by removing at least part of the endothelium of the cavity wall in order to maximize thrombosis and prevent recanalization in the vascular cavity. The method comprises the steps of endovascularly disposing at least one denuding element inside the cavity and using the at least one denuding element to remove at least part of an endothelium of a cavity wall while avoiding wall perforation.
