  • Ventricular pump coupling
    Patent number: 8932197
    Abstract: A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.

  • Apparatus and methods for use of expandable members in surgical applications
    Patent number: 8926620
    Abstract: In some embodiments, an apparatus includes an elongated member, an expandable member coupled to the elongated member, and an outer sheath. The outer sheath, which can be constructed from a different material than the expandable member, is disposed about the expandable member such that an outer surface of the expandable member is in discontinuous contact with an inner surface of the outer sheath. The expandable member and the outer sheath are configured to cooperatively displace a bone structure when moving between a collapsed configuration and an expanded configuration.
