  • Patent number: 7481838
    Abstract: A highly flexible tissue-type heart valve is disclosed having a structural stent in a generally cylindrical configuration with cusps and commissures that are permitted to move radially. The stent commissures are constructed so that the cusps are pivotably or flexibly coupled together at the commissures to permit relative movement therebetween.
    Type: Grant
    Filed: December 5, 2003
    Date of Patent: January 27, 2009
    Assignee: Edwards Lifesciences Corporation
    Inventors: Alain F. Carpentier, Stefan G. Schreck, Richard S. Rhee, Diana Nguyen-Thien-Nhon, Hung Ly Lam, William Recktenwald
  • Publication number: 20040148018
    Abstract: A highly flexible tissue-type heart valve is disclosed having a structural stent in a generally cylindrical configuration with cusps and commissures that are permitted to move radially. The stent commissures are constructed so that the cusps are pivotably or flexibly coupled together at the commissures to permit relative movement therebetween. The stent may be cloth-covered and may be a single element or may be made in three separate elements for a three cusp valve, each element having a cusp portion and two commissure portions; adjacent commissure portions for each pair of adjacent stent element combining to form the stent commissures. If the stent has separate elements their commissure portions may be pivotably or flexible coupled, or may be designed to completely separate into independent leaflets at bioresorbable couples. The cloth covering may have an outwardly projecting flap that mates with valve leaflets (e.g., pericardial leaflets) along the cusps and commissures.
