Abstract: 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.

Abstract: 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.

Abstract: An implantable circulatory support system, configured to connect a ventricular chamber of a heart, including a valveless displacement blood pump, a deformable polymeric flow cannula, a pair of male and female fasteners, a coupler, a driveline assembly, and a co-pulsatile driver. Forward and backward flow communication between the blood pump and the heart chamber is accomplished using the present flow cannula invention which is anastomosed to the heart chamber in a sutureless manner. When providing circulatory support, the co-pulsatile driver ejects blood out of the blood pump during systolic ventricular contraction and fills the blood pump with blood during diastolic ventricular relaxation.

Abstract: 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.

Abstract: An inflow cannula assembly intended for connecting a ventricular assist device (VAD) to a heart chamber without suturing anastomosis is provided. The inflow cannula assembly includes a deformable flow cannula with funnel-shaped bellmouth intake at a first end and a second end interfaced to the inlet of a VAD with minimal interface discontinuity; also includes is a pair of male and female fasteners that can be screw locked to fix and seal the cannula bellmouth against the endocardium for hemostasis purpose; as well as a VAD coupler and a VAD inlet adapter that enable a quick connection of the cannula with the VAD.

Abstract: The invention discloses a novel vascular punch employing compressive normal force for tissue separation from a targeted vessel. This invention is particularly designed for making a large round hole without massive bleeding in vascular surgery. A clean, non-frayed hole-making guided by the normal force cutting principle is realized using a site-biting punch mechanism. The side-biting vascular punch comprises a U-shaped razor blade cutter, a backstop for receiving the cutter, and a linkage mechanism, forming an aligned line of contact for normal compression force generation and thereby severing tissue out of the targeted vessel.
