Heart valve regurgitation anchor and delivery tool

A method of deploying a heart valve anchor apparatus, comprising:

• inserting a tissue penetrating device into tissue forming a heart valve annulus such that a distal end of the tissue penetrating device protrudes from the tissue, the tissue penetrating device having a heart valve anchor apparatus disposed within a lumen of the tissue penetrating device in a delivery configuration, the heart valve anchor apparatus comprising:
• a body comprising:
• a first radially expandable portion at a proximal portion of the body;
• a second radially expandable portion at a distal portion of the body;
• and
• a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent;
• wherein the first radially expandable portion is configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained;
• wherein the second radially expandable portion is configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained;
• actuating a handle element of the tissue penetrating device to push the second radially expandable portion out of the distal end of the tissue penetrating device outside of the tissue;
• withdrawing the tissue penetrating device through the tissue, thereby releasing the root portion within the tissue and the first radially expandable portion outside of the tissue, such that the first radially expandable portion and the second radially expandable portion both engage the tissue disposed between them in an unstressed configuration;
• wherein in the unstressed configuration, the body defines a longitudinal centerline that extends away from a plane tangent to the root portion.
