Anteris Technologies has been granted a patent for a transcatheter delivery system that allows for precise alignment of a replacement heart valve prosthesis with an existing valve. The system includes a balloon shaft, balloon, handle with an actuator, and a valve prosthesis loaded onto the balloon. Rotation of the actuator allows for predictable rotation of the valve prosthesis during the procedure.

A newly granted patent (Publication Number: US11883286B2) discloses a transcatheter delivery system comprising a catheter assembly with a balloon shaft, a balloon, and a handle with an actuator. The system also includes a valve prosthesis expandable by the balloon's expansion, with the actuator's rotation predictably rotating the valve prosthesis. The balloon shaft is described as a braided shaft with optional coatings, and the valve prosthesis features a valve construct attached to a frame, including radiopaque markers for visibility during procedures.

Furthermore, the patent details a variation of the transcatheter delivery system with an inner and outer shaft, a lock mechanism, and a valve prosthesis loaded onto the inner shaft. Rotation of the inner shaft predictably rotates the valve prosthesis, with the lock preventing axial movement of the inner shaft when in the locked position. The system includes a handle with a locking switch for engaging and disengaging the lock, allowing controlled rotation and movement of the inner shaft. Additional features like alignment markers on the valve prosthesis and actuator stops on the handle enhance the precision and usability of the transcatheter delivery system for medical interventions.
