Abstract
A delivery system for delivering a spiral anchor to a diseased native valve of a heart includes an anchor control catheter and an anchor guide extending from the anchor control catheter. The anchor guide includes a flexible configuration and a rigid configuration. The anchor guide in the rigid configuration includes a proximal section, a middle section, and a distal section. The proximal section includes a straight central axis and extends from the anchor control catheter, the middle section spirals axially and radially outwards from the central axis, and the distal section curves concentrically about the central axis in a plane that is perpendicular to the central axis.
