Percutaneous access sheaths used to provide access to the vasculature and heart for the introduction of percutaneous ventricular assist devices (pVADs), and to remain in place for the duration of pVAD use. The sheaths include actively closeable seals engageable to seal against the drive lines of the pVADs to minimize blood loss during pVAD use.

An intra-ventricular pulsatile assist system is provided including an intra-ventricular blood pump including a chamber having a distal portion and a proximal portion opposite the distal portion, the proximal portion and the distal portion defining an axis extending therebetween and the distal portion defining an outlet; a valve at the distal portion of the chamber, the valve including a closed position in which the outlet is sealed and an open position in which the outlet is unsealed; and a control circuit including a processor in communication with the blood pump, the processor having processing circuitry configured to determine a pressure value in the chamber and transition the valve between the closed position and the open position when the pressure value in the chamber deviates from a predetermined threshold value.

A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

A heart failure recovery device includes a fluid pump having an inlet and an outlet in fluid communication with a pump reservoir, and a pumping element disposed within the pump reservoir, the pumping element including a protrusion that in an active state is configured to rotate and move fluid away from the inlet and towards the outlet. A receiver coil can be electrically coupled to the fluid pump and is configured to subcutaneously absorb electromagnetic energy for powering the fluid pump. In certain embodiments, an implantable port provides fluid access to the pump reservoir for cleaning and maintaining the fluid pump. In other embodiments, a valve closes fluid access to at least one of the inlet and the outlet during periods when the device is not being used for treatment.
