Anteris Technologies has filed a patent for a replacement heart valve assembly that allows for easier delivery and positioning during endovascular heart valve repair. The assembly includes a stent with a locking element and a valve with leaflets and a body portion. The valve is loaded separately from the stent and is pulled towards the stent to engage the locking mechanism.

Replacement heart valve assembly for endovascular heart valve repair
A recently filed patent (Publication Number: US20230293296A1) describes a replacement valve assembly for endovascular heart valve repair. The assembly consists of a stent and a valve. The stent has a proximal end and a distal end, with an outer surface and an inner surface defining a stent lumen. It also includes at least one stent locking element. The valve, on the other hand, has a proximal end and a distal end, with at least one valve leaflet and a valve body portion connected to the leaflet. In the delivery position, the proximal end of the valve is positioned distally from the distal end of the stent.
The patent also mentions additional features of the valve. It includes a cuff at the distal end of the valve, which defines a valve channel between the cuff and the outer surface of the valve body portion. The valve also has at least one valve locking feature for engagement with the stent locking element. In the expanded position, the valve is moved in a proximal direction towards the distal end of the stent until the valve locking feature is engaged with the stent locking element, and the distal end of the stent is positioned within the valve channel. The valve locking feature is positioned within the valve channel and is described as an L-shaped flange.
Furthermore, the patent mentions the use of cable wires in the replacement valve assembly. At least one cable wire is connected to the distal end of the valve, and another cable wire is connected to the valve locking feature. The stent locking element is located at the proximal end of the stent and is aligned with the commissure of the valve body. The valve itself can be made of either tissue material or polymer.
In addition to the replacement valve assembly, the patent also describes a standalone replacement heart valve. This valve includes a valve body with at least one valve leaflet and a cuff at the distal end, overlapping a portion of the valve body. A valve channel is present between the cuff and the outer surface of the valve body. The valve also includes at least one valve locking feature, which can be positioned within the valve channel, on the outer surface of the valve body, or on the inner surface of the valve. Similar to the replacement valve assembly, the valve body and valve leaflets can be made of tissue material or polymer, and the valve locking feature can be an L-shaped flange.
Overall, this patent presents a replacement valve assembly and a standalone replacement heart valve with various features and configurations that can be used for endovascular heart valve repair.
