Abstract:
1. A device to occlude an aneurysm comprising: a laterally-expanding occluding member that is configured to be positioned within a parent vessel of the aneurysm and then expanded laterally; wherein the lateral expansion is primarily in directions that are configured to be parallel to a plane defined by a circumference of an aneurysm neck; and wherein the laterally expanding occluding member is expanded from a first configuration with a first width to a second configuration with a second width, wherein the second width is wider than the first width; and a radially-expanding structural member that is configured to be positioned within the parent vessel of the aneurysm and then expanded radially; wherein the radially-expanding structural member is configured to span a section of the parent vessel that includes the aneurysm neck; wherein the radially-expanding structural member is expanded from a first configuration with a first diameter to a second configuration with a second diameter, wherein the second diameter is larger than the first diameter; wherein the radially-expanding structural member is structurally resilient to maintain the second configuration after expansion while the radially-expanding structural member is configured to be within the parent vessel; wherein the radially-expanding structural member is positioned on a side of the laterally-expanding occluding member that is configured to face away from the aneurysm neck, such that the laterally-expanding occluding member is configured to be between the radially-expanding structural member and the aneurysm neck; and wherein expansion of the radially-expanding structural member presses and holds the laterally-expanding occluding member such that the laterally-expanding occluding member is configured to be in direct contact with the aneurysm neck, so that the laterally-expanding occluding member is configured to be at least partially covering the aneurysm neck and reduces blood flow to the aneurysm.
