Abstract
A pump for inducing flow within a vascular system comprises a cannula having a first configuration for deployment within the vascular system and a second configuration for directing the fluid flow within the vascular system, where the second configuration has a greater diameter than the first configuration. An impeller is configured to induce the fluid flow by rotation about an axis. The impeller has a first radius in the first configuration and a second radius in the second configuration, where the second radius is greater than the first radius.
