Abstract
Some pump impellers used in mechanical circulatory support systems such as percutaneous ventricular assist devices can be expandable. Some such impellers can be inflatable, for example. Some inflatable impellers can have an inflatable main body and a plurality of inflatable fins extending along the main body in a linear or a spiral arrangement. In some cases, such fins can be non-inflatable. Such fins can also be coupled to each other in an arrangement of two or more fin members in a stacked configuration.
