Endo-leak free aortic adapter assembly and method of device delivery

A blood pump device, for an implantable ventricular assist device, comprising:

• a blood pump, having an inlet adapter, wherein the inlet adapter has a cone-shaped beak;
• an aortic adapter assembly, for an implantable ventricular assist device, comprising:
• a T-shaped flow connector, including:
• an inserted conduit portion and an extruded neck portion;
• wherein the inserted conduit portion is joined with the extruded neck portion;
• both having a blood-contacting surface which is smooth;
• 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 the inlet adapter of a blood pump;
• wherein the cone-shaped beak is able to fit with the proximal end of the extruded neck portion.
