An aortic adapter assembly is provided, including a T-shaped flow connector, including: an inserted conduit portion, having a blood-contacting surface which is smooth; an extruded neck portion, wherein the inserted conduit portion is joined with the extruded neck portion; and a truss, disposed in the inserted conduit portion; wherein the T-shaped flow connector has a polymeric elastomer reinforced by the truss having a Nitinol material; wherein the inserted conduit portion has an inner wall which is gradually thinning at two conduit ends of the inserted conduit portion, with a proper distance of a tip of the conduit end to the outmost boundary of the truss, and the conduit end possesses a compliance-matching effect to an implant site artery; wherein a proximal end of the extruded neck portion is configured to be joined with an inlet adapter of a blood pump. The aortic adapter assembly is accompanied with a quick-connector type coupler and a deployment method to accomplish an insertion type flow communication between a ventricular assist device and the human circulation.

A para-aortic blood pump device includes a blood pump, an aortic adapter, a driveline, and a driver. The blood pump includes a blood sac, a pump housing and a pressure sensor, whereas the pressure sensor is installed in the pump housing for monitoring the blood pressure inside the blood pump. The aortic adapter is a T-manifold shaped conduit connected to the blood pump and is used for connecting the blood pump with human aorta to facilitate circulatory support. The driveline allows a pneumatic communication to the blood pump in addition to transmitting the electrical blood pressure signal to the driver. The driver receives and processes the electrical blood pressure signal, decides the timing, speed and duration of blood pump fill and eject actions so as to provide counter-pulsatile circulatory support to assist human circulation.

A ventricular assist device is provided, including a blood pump, a driveline and a feedthrough. The blood pump includes a pump housing, an axi-symmetric oval-shaped blood sac and stem assembly received in the pump housing, and a pressure sensing system embedded in the pump housing. The driveline includes a pneumatic lumen, at least one electric wire and a tether included in a wall of the driveline, wherein the electric wires and the tether are disposed on the pneumatic lumen. The feedthrough connects the driveline to the pump housing.
