AN ENDOVASCULAR OCCLUSION DEVICE

Abstract: the present invention is concerned with an endovascular occlusion device for use in occluding a lumen of the endovascular system to treat certain medical conditions such as vascular malformations, bleeding vessels or occluding vessels in order to induce tissue ischemia or necrosis, the occlusion device including a deformable sleeve displaceable between a collapsed state and an expanded state and a conical array of cantilevered arms extending from a distal end of the sleeve and converging towards distal tips such as to define a first haemostatic valve about the distal end of the sleeve. the distal end of the sleeve will be at least partially covered with a polymer fluid impermeable membrane in order to provide a seal to prevent fluid flow through the occlusion device. the internal valve will be haemostatic regardless of the initial direction of blood flow and will allow distal endovascular delivery of a surgical instrument such as a catheter that can be manipulated and used to deliver therapeutic agents such as liquid or small particle embolics.
