A Stented Autologous Valve Prosthesis

Brief Description of the Invention:
This invention introduces a stented autologous aortic valve prosthesis designed to replace the diseased aortic valve during cardiac surgery, aiming to reduce complications related to clotting,hemolysis, infection, patient-prosthesis mismatch, dysfunction, and the need for strong anticoagulation.
To address these issues and minimize the time the patient is on cardiopulmonary bypass, the invention features a two-part system. The first part consists of a flexible, expandable structure with a predetermined radial diameter that can be reduced for insertion into the aorta and expanded. This adaptability enables secure positioning while minimizing patient-prosthesis mismatch. Before positioning, the first part, along with the second part (which includes at least one protrusion), is assembled outside the heart with at least three equally-sized leaflet pockets, formed with a fabric graft. This system facilitates a smoother and more efficient surgical process, performed in an open environment to enhance surgeon control and reduce procedural risks. This innovative stented autologous valve prosthesis thus offers an improved alternative for aortic valve replacement, especially in patients requiring reduced anticoagulant dependency and a closer hemodynamic match within the annulus.
