Hyderabad surgeon patents US heart valve that eliminates need for blood thinners

A cardiac surgeon based in Hyderabad has been granted a United States patent for a new heart‑valve design that aims to stop clot formation without the routine use of anticoagulant drugs. The device incorporates a specialized leaflet geometry and surface coating that promote laminar blood flow, reducing the likelihood of thrombus development inside the valve. By eliminating the need for long‑term blood‑thinners, the valve could lower the risk of bleeding complications that many patients experience after valve replacement surgery. The inventor plans to commence clinical trials in India later this year, after completing pre‑clinical safety assessments and obtaining regulatory clearance. If successful, the technology could expand treatment options for Indian patients with valve disease and position the country as a hub for innovative cardiac devices.
