Patent number: 11744705Abstract: A method of implanting a percutaneous heart valve prosthesis via a catheter. The heart valve prosthesis includes a valve body frame made of a nickel-titanium alloy. The valve body frame is collapsible for fitting within the catheter. A flexible skirt is sutured to the valve body frame for blocking retrograde blood flow. A one-way valve is positioned within the valve body frame for permitting blood to flow from a first end of the valve body frame to a second end. The one-way valve is preferably formed by three flexible valve leaflets made from a pericardial material. A plurality of barbs is spaced about the periphery of the valve body frame. Each of the prongs points toward the first end of the valve body frame for preventing migration of the heart valve prosthesis towards an atrium of the heart.Type: GrantFiled: December 15, 2021Date of Patent: September 5, 2023Assignee: Percutaneous Cardiovascular Solutions Pty LtdInventors: Suku Thambar, Stayajit Rohan Jayasinghe

Patent number: 10856858Abstract: A method of treating a heart includes radially expanding a housing component within a native atrioventricular valve. The housing component includes an atrial anchoring mechanism for deployment in the left atrium and ventricular prongs for engagement with native tissue in the left ventricle. The housing component also includes an interior passageway sized for receiving a valve component. After the housing component has been deployed, the valve component is radially expanded within the passageway of the housing component. The valve component includes three leaflets configured for allowing blood to flow from the left atrium to the left ventricle. After expansion within the housing component, the valve component may have an inflow end portion that protrudes above the housing component into the left atrium. The housing component and valve component are preferably collapsible for advancement through a patient's vasculature using one or more catheters.Type: GrantFiled: December 19, 2018Date of Patent: December 8, 2020Assignee: Percutaneous Cardiovascular Solutions Pty LtdInventors: Suku Thambar, Martin Christopher Cook, Stefan Schreck, Stayajit Rohan Jayasinghe

Patent number: 10213298Abstract: A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6). A failed or failing mitral heart valve (101) is treated by percutaneously locating the valve body (2) in the mitral valve orifice (102) with the anchor device (5) located in the right atrium (107) and engaging the inter-atrial septum (103), such that the taught anchor line (6) acts to secure the valve body (2) within the mitral valve orifice (102).Type: GrantFiled: February 16, 2015Date of Patent: February 26, 2019Assignee: Percutaneous Cardiovascular Solutions Pty LtdInventors: Suku Thambar, Stayajit Rohan Jayasinghe
