What changed
USPTO published patent application US20260108349A1 for heart valve prostheses and transcatheter devices. The application describes an expandable anchoring frame with an interior area extending between proximal and distal portions, with an expandable stent frame containing a prosthetic valve structure mounted within. The stent frame is configured to be inserted into the anchoring frame interior and, when expanded, is biased radially outward to capture native leaflets between the stent frame outer surface and anchoring frame inner surface.
Affected parties include medical device manufacturers in the cardiac prosthetics space, cardiovascular device developers, and entities pursuing transcatheter valve technology. This publication establishes prior art and signals an active patent filing in the transcatheter heart valve space that could affect freedom-to-operate analyses for competing device developers.

Abstract
A heart valve prosthesis that includes an expandable anchoring frame having an interior area extending between a proximal portion of the expandable anchoring frame and a distal portion of the expandable anchoring frame. An expandable stent frame includes an interior area. A prosthetic valve structure is mounted within the interior area of the expandable stent frame. The expandable stent frame is configured to be inserted into the interior area of the expandable anchoring frame and, when the expandable stent frame is in an expanded configuration, the expandable stent frame is biased radially outward toward an inner surface of the expandable anchoring frame and is dimensioned to capture the at least one native leaflet between an outer surface of the expandable stent frame and the inner surface of the expandable anchoring frame.
