Abstract:
1. A system for replacing a heart valve, comprising: an expandable anchor having a collapsed delivery configuration and an expanded configuration, the expandable anchor comprising a distal end; a replacement valve commissure support element attached to the expandable anchor; a commissure portion of a replacement valve leaflet attached to the commissure support element; and a fabric seal at least partially disposed around an exterior portion of the expandable anchor when the anchor is in the expanded configuration, the fabric seal having an undeployed state and a deployed state, wherein in the deployed state the fabric seal comprises flaps that extend into spaces formed by native valve leaflets; wherein a distal end of the replacement valve leaflet is attached to the fabric seal and when the expandable anchor is in the collapsed delivery configuration, the fabric seal extends from the distal end of the replacement valve and back proximally over the expandable anchor, the fabric seal being adapted to prevent blood from flowing between the fabric seal and heart tissue.
