Abstract

See full text

Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.
