Thin film metallic devices for plugging aneurysms or vessels

摘要

An embolisation element (12) comprising a thin film of shape memory material having a plurality of pores (18) extending through the thin film, the embolisation element having a collapsed state and an expanded state in which the embolisation element assumes a generally funnel-shaped configuration in the expanded state, the generally funnel-shaped configuration of the embolisation element in the expanded configuration having a proximal end portion and a distal end portion that is sized and shaped to plug the neck of the aneurysm; an anchor element (14) for securing the embolisation element (12) within a blood vessel of a patient and, at least one connector element (16) connecting the embolisation device to the anchor element.
