  • Patent number: 10092402
    Abstract: Devices and methods provide enhanced treatment of a cardiac valve annulus. Methods generally involve contacting an anchor delivery device with the valve annulus and releasing a plurality of coupled anchors from the anchor delivery device to secure the anchors to the annulus. Anchors, which in some embodiments are super-elastic or shape memory self-securing anchors, are then drawn together to tighten the annulus. Devices generally include an elongate catheter having a housing at or near the distal end for releasably housing a plurality of coupled anchors. The housing may be flexible, may conform to a valve annulus, and in some embodiments may be coupled with an expandable member to enhance contact of the housing with annular tissue. In one embodiment, self-securing anchors lie approximately flat within the delivery device housing, allowing anchors with relatively large deployed shapes to be housed in and deployed from a relatively narrow delivery device.
