Heart failure leaves patients with weakened hearts that can’t pump enough blood. Current devices, like Left Ventricular Assist Devices (LVADs), require risky open-heart surgery, cause long-term dependence on the machine, and often damage blood cells. Smaller, less invasive pumps exist, but they spin so fast they damage blood and can’t be used long-term.
Core Features
This invention is a new implantable blood pump that sits in or replaces a small section of the aorta (the main artery from the heart). Unlike older pumps, it uses larger blades and a stable housing that matches the vessel’s size, allowing smoother blood flow. It can be implanted through minimally invasive methods or via surgery, depending on patient needs.
Inventive Step
The breakthrough is designing the pump so it engages with or replaces part of the artery wall. This gives it more space for bigger blades and built-in bypass channels, which reduce blood damage. The impeller (the rotating part) is also magnetically levitated—meaning it floats without grinding bearings—further protecting blood from clotting and damage.
Benefits
- Less invasive than LVADs—can be implanted with techniques like those used for heart valve replacements.
- Safer for blood: reduces risk of clotting and cell damage.
- Versatile: can be used in frailer patients who can’t undergo major surgery.
- Failsafe: if the pump stops, natural blood flow can continue through bypass channels.
- Adaptable: can operate in continuous or pulse mode to better match natural heart rhythms.
Broader Impact
This device could greatly expand access to life-saving heart support, reduce complications, and lower costs compared to LVADs. It may allow many more patients to live longer, higher-quality lives while waiting for transplants—or even avoid transplants altogether. By reducing surgery risks and improving efficiency, it advances both patient care and healthcare sustainability.
