Patent

CA 2549323

Implantable occlusion devices that include one or more flanges extending from a tubular body are disclosed. The flange or flanges may assist in retention of the device within a vessel, cavity, appendage, etc. At least one flange on the occlusion device may include a concave surface proximate one end of a body. Because of the shape of the flange, e.g., its concavity, the occlusion device may resist dislocation due to e.g., the forces generated within the left atrial appendage during atrial filbrillation.

Dispositifs d'occlusion implantable comprenant une ou plusieurs brides s'étendant depuis un corps tubulaire. Cette bride ou ces brides peuvent contribuer à retenir le dispositif à l'intérieur d'un vaisseau, d'une cavité ou d'un appendice. Au moins une bride de ce dispositif d'occlusion peut présenter une surface concave située à proximité d'une extrémité d'un corps. Etant donné la forme de la bride, par exemple, sa concavité, ce dispositif d'occlusion peut résister à la dislocation pouvant être provoquée par les forces générées à l'intérieur de l'appendice auriculaire gauche pendant une fibrillation auriculaire.
