SmartHeart Left Ventricular Assist Device:
The SmartHeart LVAD is comprised of an implanted centrifugal blood pump which is placed in the patient's chest below the heart. The pump takes blood from the patient's left ventricle via a titanium inlet cannula and returns it to the ascending aorta via a coated Dacron graft. The implanted pump is fabricated from titanium with a biocompatible coating applied to a portion of the blood-contacting surfaces. A power cable extends from the implanted pump through the skin to an external controller which powers the pump and regulates pump speed.

The SmartHeart LVAD's elegant, simple design is intended to provide long term reliability and minimize complications. The pump's rotor, it's single moving part, turns on a hemodynamic bearing, a thin film of blood which supports and stabilizes the spinning rotor, obviating the need for mechanical bearings or other wear elements. This feature combined with the optimized blood flow path allows for minimal on-going anticoagulation. Since this design does not require active magnetic stabilization, the percutaneous power cable is small and flexible, minimizing exit site infections. The pump's small profile and integrated inlet cannula provide for intra-thoracic placement even in patients of small stature, reducing placement time and minimizing surgical complications.

The SmartHeart is the only continuous flow LVAD with automatic control, that ability to respond the patient's activity levels and physical needs, as its primary mode of operation. This automatic control system is integrated into the brain of the system, the Patient Electronics Module (PEM). The small and lightweight PEM automatically controls the pump's speed based on parameters provided by the physician and outputs critical parameters such as flow rate, pressures other hemodynamic parameters. It also logs these key parameters for later examination by the treating physician. The PEM communicates with a programming and display monitor The system is powered by interchangeable rechargeable batteries, which provide the patient with several hours of mobility between battery changes.
