Implant devices, systems, and methods for annulus reduction

A delivery system comprising:

• a delivery catheter;
• a delivery device deliverable through the delivery catheter to a treatment site;
• and
• an implantable annuloplasty device configured to reshape a cardiac valve annulus having a proximal end coupled to the delivery device and a distal end configured to be secured to tissue at the treatment site, the implantable annuloplasty device deliverable through the delivery catheter to the treatment site;
• wherein:
• the delivery device comprises at least one elongated member;
• the implantable annuloplasty device is expandable from a collapsed delivery configuration to an expanded deployment configuration while coupled to the delivery device;
• a proximal section of the implantable annuloplasty device adjacent the proximal end of the implantable annuloplasty device remains at a smaller angle with respect to the at least one elongated member of the delivery device than does a middle section of the implantable annuloplasty device extending distally from the proximal section when the implantable annuloplasty device shifts from the collapsed delivery configuration to the expanded deployment configuration while coupled to the delivery device;
• wherein the implantable annuloplasty device includes a tubular frame;
• wherein an outward bend is provided adjacent and spaced from a proximal end of the tubular frame to form the proximal section of the implantable annuloplasty device;
• wherein the outward bend defines a region of the tubular frame that is disposed radially outward of the proximal end of the tubular frame;
• wherein an inward bend is provided adjacent and spaced from a distal end of the tubular frame to form an anchoring section of the implantable annuloplasty device and
• wherein the tubular frame comprises a plurality of struts joined along proximal apices, and the outward bend is formed adjacent at least one of the proximal apices.

An implantable annuloplasty device, comprising:

• a tubular frame extending about a frame axis and having a proximal end configured to be coupled to a delivery device and a distal end configured to be secured to tissue;
• wherein the tubular frame has a middle section, a proximal section extending between the proximal end of the tubular frame and the middle section, and an anchoring section extending between the middle section and the distal end of the tubular frame;
• wherein the proximal section of the tubular frame bows outwardly relative to the proximal end of the tubular frame and the middle section;
• and
• wherein the anchoring section of the tubular frame extends radially inward relative to the middle section.
