Pulsatile blood pump

Research output: Patent

Abstract

There is described a pulsatile blood pump for implantation into a patient. The blood pump comprises a flexible, substantially tubular body for disposal coaxially within a blood vessel of the patient. The tubular body has first and second ends with a blood passageway extending therebetween for the passage of blood, and the tubular body has a collapsed state for use during delivery and an expanded state for use during pumping. The blood pump further comprises deformable elements coupled to the tubular body and arranged to retain the tubular body in the expanded state following delivery. The blood pump further comprises a flexible membrane attached to the tubular body so as to form a fluid chamber within the tubular body. The flexible membrane separates the fluid chamber from the blood passageway. In the expanded state of the tubular body, the blood pump is arranged such that fluid is able to flow into and out of the fluid chamber whereby the volume of the fluid chamber increases and the volume of the blood passageway decreases when fluid flows into the fluid chamber, and whereby the volume of the fluid chamber decreases and the volume of the blood passageway increases when fluid flows out of the fluid chamber, thereby enabling the blood pump to pump blood along the blood passageway. There is also described a blood pump system comprising the present blood pump, a method for the treatment of heart failure in a patient using the present blood pump, and a method for augmenting peripheral blood circulation in a patient using the present blood pump.
