Prosthetic Heart Valve with Paravalvular Leak Mitigation Features
Summary
USPTO published patent application US20260090880A1 by St. Jude Medical for a prosthetic heart valve with paravalvular leak mitigation features. The application claims novel cuff configurations and finger elements positioned radially outward from stent cells, along with tapered struts for improved fatigue resistance. The filing date is December 8, 2025.
What changed
St. Jude Medical, Cardiology Division filed patent application US20260090880A1 disclosing a prosthetic heart valve design incorporating dual cuff structures and radially extending finger elements to address paravalvular leakage. The first cuff is disposed adjacent the stent while the second cuff with distal edge faces the outflow end and is positioned radially outward. The finger elements have first ends coupled to stent cells with free ends extending radially outward. The application also claims tapered stent struts to reduce collapsed circumference and improve fatigue resistance and bendability.
This is a patent application publication with no immediate compliance obligations. Medical device manufacturers developing transcatheter heart valves may reference this application to understand St. Jude Medical's design direction and avoid potential future infringement. No action is required at this time as patent applications do not create binding regulatory requirements.

Abstract
A prosthetic heart valve includes a collapsible stent and a valve assembly disposed within the stent. A first cuff is disposed adjacent the stent. A second cuff having a distal edge facing the outflow end of the stent is disposed about the stent radially outward of the first cuff and the stent. The stent may include a plurality of fingers each having a first end coupled to a corresponding cell of the stent and a free end adapted to extend radially outward of the corresponding cell. The distal edge of the second cuff may be coupled to the fingers at spaced locations around the circumference of the stent to position the distal edge radially outward from the corresponding cells at the spaced locations. Various stent struts may be tapered to reduce the stent circumference in the collapsed condition, and to improve the fatigue resistance and/or bendability of the stent.
