Systems and methods for predictable commissural alignment of a replacement heart valve
Summary
The USPTO granted patent US12594161B2 to Anteris Technologies Corporation covering a balloon-mounted replacement heart valve prosthesis with a catheter system that allows rotational alignment of the valve commissures during implantation. The patent includes 20 claims covering the catheter handle actuator mechanism enabling predictable commissural alignment. The filing date was December 21, 2023, with application number 18393475.
What changed
USPTO issued patent grant US12594161B2 to Anteris Technologies Corporation for a replacement heart valve prosthesis loaded onto a balloon catheter system. The invention features a rotatable balloon shaft engaged with a handle actuator allowing controlled rotation of the valve prosthesis by a known amount during the procedure, enabling predictable commissural alignment between the replacement valve and the native valve. The patent contains 20 claims covering the catheter handle, actuator mechanism, and alignment method.
For medical device manufacturers and cardiovascular device developers, this patent defines intellectual property boundaries around rotational alignment mechanisms for transcatheter heart valve systems. Competitors developing similar balloon-mounted delivery systems with rotational control features should review this patent for potential infringement exposure. The patent's broad claim scope covering the actuator-to-shaft rotatable engagement may affect product development strategies in the transcatheter aortic valve replacement (TAVR) space.

Abstract
A replacement heart valve prosthesis is loaded onto a balloon mounted onto a balloon shaft of a catheter system. The balloon shaft is rotatably engaged with an actuator on the handle of the catheter system. Rotation of the actuator by a first amount in a first direction permits rotation of the heart valve prosthesis by a known amount during the procedure so that alignment of the commissures of the replacement valve with the commissures of the existing valve can be predictably achieved.
