Abstract
A pump for inducing flow within a vascular system comprises two inlets. The pump has a first configuration for deployment within the vascular system and a second, operable configuration for directing the fluid flow within the vascular system, where the second configuration has a greater diameter than the first configuration. A centrifugal impeller is configured to induce the fluid flow by rotation about an axis of rotation, where the flow is in a direction generally transverse to the impeller's axis of rotation.
