ABSTRACT:
A cannula pump is provided which incorporates a miniature rotary pump into a cardiac cannula of essentially the same size as currently utilized with routine cardiopulmonary bypass. The pump may be inserted via a single small incision in the heart to obtain both inflow and outflow cannulation simultaneously, and provide sufficient flow to completely unload the ventricle during its use. Because application of the device is extraordinarily simplified, it is suitable for rapid emergency insertion in any setting where the chest can be safely opened, including emergency room and battlefield applications. A small electric motor, implanted within the heart, provides power to the impeller via a small shaft supported on blood immersed bearings. A disposable cannula pump utilized with a reusable motor provides an inexpensive device for routine surgical use.
