Abstract
Abstract The invention relates to an assembly for the removal of a stent from a body vessel without an operation being necessary to gain access to this stent. This assembly comprises for this purpose an expandable element, connected to a pulling device, the outer surface of which is covered with an adhesive medium and which, when the element is positioned inside the stent, is expanded and lies with its outer surface against the inner surface of the stent and thereby causes an attachment between this outer surface and the inner surface of the stent. The element with the stent attached to it can be then be withdrawn via the body vessel.
