Mitral valve annuloplasty device with twisted anchor

A mitral valve therapy device, the therapy device comprising:

• an expandable first anchor, an expandable second anchor, and a connecting member extending therebetween, a distal end, a proximal end, and an axis that extends between the distal and proximal ends and along the connecting member,
• the expandable first anchor having an anchored configuration in which a first anchor apex is in an anchor portion that is spaced radially furthest away from the axis,
• the expandable first anchor comprising a first segment and a second segment, and in the anchored configuration the first segment engages the second segment to form at least one full twist around the second segment in the apex of the expandable first anchor in which the first segment passes over the second segment and then under the second segment and then over the second segment, and in which the second segment passes under the first segment and then over the first segment and then under the first segment,
• the expandable first anchor further comprising a securing member for securing an end of the first segment and an end of the second segment therein at a distal end of the securing member, the securing member generally aligned with the connecting member,
• the first segment extending distally from the securing member, below the axis and away from the apex, and forming a first stress relief portion, the second segment extending distally from the securing member, below the axis and away from the apex, and forming a second stress relief portion,
• wherein the first and second stress relief portions are located distal to where the first and second segments form the at least one full twist.
