  • Crimping heart valve with nitinol braid
    Patent number: 10898326
    Abstract: A system for crimping a fully deployed heart valve includes a delivery tube extending in a longitudinal direction and having a lumen for receiving the crimped heart valve, a deployment device including a first member and a second member moveably secured to the first member, and a sheath configured to at least partially enclose a radially collapsible stent. A first attachment area of the sheath is connected to the first member and a second attachment area of the sheath is connected to the second member such that movement of the first member relative to the second member tensions the sheath for crimping the heart valve. A method of crimping a fully deployed heart valve is also provided.
