Abstract: An example introducer and method of use is disclosed. The example introducer sheath includes a shaft including a tubular portion, an expandable portion coupled to the tubular portion and a longitudinal axis. Additionally, the expandable portion includes a first pair of leaflets and a second pair of leaflets and both the first pair of leaflets and the second pair of leaflets extend along the longitudinal axis. Additionally, the second pair of leaflets are spaced radially inward of an inner surface of the first pair of leaflets and the expandable portion is designed to shift between a first configuration and a second expanded configuration.

Abstract: A percutaneous circulatory support device includes a housing and an impeller disposed within the housing and being rotatable relative to the housing to cause blood to flow through the housing. A cannula is coupled to the housing, and a distal tip portion is coupled to the cannula opposite the housing. A control wire is movable to modify at least one of a radius, a stiffness, and a shape of the distal tip portion.
