A transcatheter occluder device (1) for closing an opening in a tissue wall for the repair of cardiac defect has a body member formed of an open cell polymer foam which can be held in a desired occluder shape but is resiliently compressed for transcatheter deployment. The defect occluder (1) comprises a pair of spaced-apart discs (2, 3) joined by a narrow plug (4). Encapsulated within the body member are three spaced-apart reinforcing and anchoring clips (5) of substantially C-shape each having a pair of retaining arms (6) projecting from a central support stock (7). Because the anchoring clips (5) are separate, there is no kinetic loading on one anchorage clip (5) due to the movement of another anchorage clip (5). The anchorage clips (5) will therefore move with the issue wall. |
