Summary
The USPTO granted Patent US12605246B2 to St. Jude Medical, Cardiology Division, Inc. on April 21, 2026. The patent covers a prosthetic heart valve with an atrial drain design featuring an inner frame positioned radially inward of an outer frame, connected by plural connecting arms, with a bridging skirt extending from the outer sealing skirt to the inflow edge of the inner sealing skirt to cover the gap between the frames. The patent contains 20 claims.
“A bridging skirt extends from the outer sealing skirt to an inflow edge of the inner sealing skirt.”
What changed
The USPTO issued Patent US12605246B2 to St. Jude Medical, Cardiology Division, Inc. for a prosthetic heart valve featuring a dual-frame architecture with an inner frame mounted radially inward of an outer frame, connected by plural connecting arms. A bridging skirt extends from the outer sealing skirt to the inflow edge of the inner sealing skirt to cover the gap between the inner and outer frames. The inner sealing skirt may include one or more trenches interrupting the circular inflow edge shape.
Manufacturers and developers of transcatheter heart valve systems should review this patent when designing similar dual-frame or bridging-skirt valve structures to assess potential freedom-to-operate considerations. Medical device companies active in the prosthetic heart valve space should evaluate whether their own products incorporate the claimed structural elements, including trench features on inner sealing skirts and bridging skirt coverage of inter-frame gaps.

Abstract
A prosthetic heart valve includes an outer frame, an outer sealing skirt, an inner frame, an inner sealing skirt, a plurality of prosthetic leaflets mounted within the inner frame, and a plurality of connecting arms connecting the inner frame to the outer frame so that the inner frame is positioned radially inward of the outer frame. A bridging skirt extends from the outer sealing skirt to an inflow edge of the inner sealing skirt. The bridging skirt covers a gap between the inner frame and the outer frame. The inner sealing skirt may include at least one trench that interrupts an otherwise circular shape of the inflow edge of the inner sealing skirt, the trench extending in an outflow direction of the prosthetic heart valve.
