Demonstration of a low cost implantable blood pump

A new, smaller heart pump is being tested in the lab and in animals to prove it is safe and effective enough for human trials. Advanced heart failure affects a growing number of patients, and current treatments have serious limits. Drugs and pacemakers often stop working, and donor hearts are scarce. Existing mechanical pumps (ventricular assist devices, or VADs) can keep people alive, but they cost tens of thousands of pounds, cause frequent complications like bleeding and infection, and require major open-heart surgery to implant. The Calon MiniVAD is designed to be smaller, gentler on blood cells, and cheaper to manufacture and use. If the MiniVAD passes these safety tests, it could enter human clinical studies. Success would mean a less invasive implant procedure, fewer hospital readmissions from pump-related complications, and lower overall costs for the NHS. For patients with end-stage heart failure who are not candidates for transplant, this could transform a short, restricted life into years of relatively normal activity. The project does not study the fundamental biology of heart failure; it is an engineering and regulatory step toward a specific medical device.
