DuraHeart LVAS

The DuraHeart LVAS is engineered to dramatically decrease the risk of cell damage and its related complications.

The system’s blood-friendly features are designed to:

REDUCE HEMOLYSIS AND THROMBUS FORMATION

• Actively controlled, magnetically levitated impeller helps minimize turbulence by promoting gentle and consistent flow patterns
• Unmatched wide, stable spacing between the impeller and chamber wall helps minimize pump-induced hemolysis by providing ample room for smooth, unimpeded flow and proper washout
• Consistent primary and secondary flow patterns help improve washout and reduce the potential for stasis, turbulence and, ultimately, pump thrombus

SIMPLIFY SURGERY AND CLINICAL FOLLOW-UP

• Angled inflow conduits in 3 sizes allow for optimal pump positioning
• No pre-clotting or coating required of the Vascutek Gelweave™ Outflow Graft
• Disk-shaped pump provides better anatomic fit
• Accurate flow measurements without the need for flow sensors

RESPOND TO EXERCISE

• Sensitivity to patient heart rate, preload and after load provides immediate physiologic-responsive flow
• Low shut-off pressure minimizes risk of ventricular suction
• No ventricular suction events1

IMPROVE SAFETY, RELIABILITY, DURABILITY

• Magnetically levitated impeller completely eliminates need for a mechanical bearing in the blood chamber
• Zero-contact impeller operation eliminates friction, minimizing heat production that can contribute to thrombus formation
• Failsafe hydrodynamic support system provides peace of mind as a back-up to magnetic levitation
