Abstract: A percutaneous circulatory support device includes a housing comprising an inlet and an outlet, an impeller disposed within the housing and being rotatable relative to the housing to cause blood to flow into the inlet, through the housing, and out of the outlet, a cannula coupled to the housing, the cannula extending between a proximal section and a distal section opposite the proximal section, and an expandable element configured for inflation and deflation, the expandable element having a length that is approximately equal to a length of a body of the cannula. The expandable element is configured for providing an increased stiffness to the cannula.

Abstract: An example introducer is disclosed. An example introducer includes a tubular member including an inner layer and an outer layer, the inner layer having an inner surface, an outer surface and wall extending therebetween. The outer layer is disposed along the outer surface of the inner layer. The inner layer includes a plurality of longitudinal channels extending radially outward from the inner surface. Each channel of the plurality of channels has a circumferential width. Further, the tubular member is designed to shift from an unexpanded configuration to an expanded configuration, wherein the width of each channel increases as the tubular member shifts from the unexpanded configuration to the expanded configuration.
