Abstract
An improved inflow conduit for an implantable ventricular assist device comprising covering the flexible porous tubular graft body of the conduit with an attached non-porous polymer to produce a non-porous conduit. The flexible conduit has an upstream end and a downstream end, a ventricular attachment structure to which the upstream end of the body connects; and a coupling fitting on the downstream end of the body. Also taught is a combination of the improved inflow conduit with an implantable ventricular assist device. A method for the treatment of congestive heart failure, comprising implanting the implantable ventricular assist device in a patient in need of such treatment, as well as an article of manufacture, comprising packaging material and the implantable ventricular assist device contained within the packaging material are also provided.
