Method of implanting prosthetic heart valve in native valve
A recently granted patent (Publication Number: US12011351B2) outlines a method for treating a native valve in a patient's heart using a specialized valve catheter system. The method involves advancing the catheter over a guidewire through the patient's vasculature to position an expandable prosthetic heart valve adjacent to the treatment site in the heart. The prosthetic valve, in a collapsed state, is exposed and allowed to self-expand while remaining attached to flexible metal extension arms. A release mechanism is then actuated to detach the prosthetic valve from the extension arms, leaving it in place to replace the function of the native heart valve. The system includes features such as a rotator knob for controlled advancement, a lead screw mechanism for retracting the valve, and tethers for releasably retaining the prosthetic valve on the extension arms.
Furthermore, the patent details additional aspects of the method, including the use of a radiopaque band on the tubular sleeve, a hydrophilic coating on the sleeve, and the incorporation of shape memory materials for the extension arms. The method also involves reorienting the prosthetic valve relative to the native valve before final release, ensuring proper positioning and function. The system's design allows for precise and controlled deployment of the prosthetic valve, with mechanisms for both expansion and retraction as needed. Overall, the patented method offers a comprehensive approach to treating native heart valves, providing a detailed and innovative solution for patients in need of valve replacement procedures.
