METHODS AND APPARATUS FOR ACTIVE OR PASSIVE ASSISTANCE IN THE CIRCULATORY SYSTEM An apparatus for pumping blood in an animal, comprising: an outer cage (1040) movable from a substantially cylindrical stowed position to a deployed position and having a midsection that is substantially open to flow of blood in the deployed position; a pumping element (1060) rotatable within said outer cage (1040), said pumping element (1060) movable from a stowed position to a deployed position, said pumping element (1060) including a circumferentially continuous flexible outer member (1061) supported by an inner cage (1063) in the deployed position, said pumping element (1060) having a distal end, a proximal end, and a deployed midsection of greatest diameter intermediate of the distal and proximal ends and wherein rotation of said deployed pumping element (1060) provides flow of blood radially outward from the midsection of said pumping element (1060) and through the midsection of said outer cage (1040). |
