Abstract
Systems and methods for mitral valve repair having a docking station and a valve implant. The docking station is an anchoring device having a helix structure. The valve implant is made of an expandable frame and a valve, and is radially expandable to a diameter that is at least the same as an expanded diameter of the anchoring device. The method of delivering the docking station and valve implant is performed by inserting the components through device delivery catheters.

A system for replacing a cardiac valve, the system comprising:
- a first lumen comprising a proximal end and a distal end;
- a handle;
- a pushrod comprising a proximal end and a distal end, wherein the pushrod is slidably disposable in the first lumen;
- an anchor disposable in the first lumen, wherein the anchor comprises at least two helical turns in a deployed configuration;
- a second lumen comprising a proximal end and a distal end;
- an inner shaft disposed in the second lumen;
- and
- a replacement valve disposable in the second lumen, wherein the second lumen and inner shaft are configured such that retracting the second lumen uncovers the replacement valve;
- wherein the replacement valve comprises a replacement valve body including replacement valve leaflets;
- and
- wherein the first lumen and the second lumen are within a single catheter.
A system comprising:
- a catheter comprising a lumen, a proximal end, and a distal end;
- a handle connected to the catheter at the proximal end of the catheter;
- an anchor, wherein the anchor is transitionable between a straightened configuration, which can be disposed within the lumen for transvascular delivery through an opening in a blood vessel to a cardiac valve of a heart, and a deployed configuration comprising at least two turns;
- a replacement valve, wherein the replacement valve comprises an expandable frame and a valve body, wherein the valve body comprises multiple pieces of animal tissue sewn or bonded together to form replacement leaflets that can open to allow blood flow therethrough and close to prevent blood flow therethrough;
- wherein the replacement valve can transition from a collapsed configuration, for transvascular delivery through the opening in the blood vessel to the cardiac valve, to an expanded configuration;
- wherein the anchor can be transvascularly delivered through the lumen of the catheter to the cardiac valve such that at least one of the at least two turns encircles leaflets of the cardiac valve, and the replacement valve is configured such that the replacement valve can be transvascularly delivered to the cardiac valve in the collapsed configuration and expanded to the expanded configuration inside the anchor and thereby secure the replacement valve and the anchor at the cardiac valve;
- and
- wherein the expandable frame comprises a stent comprising a plurality of woven wires.
A system comprising:
- a first catheter comprising a first lumen;
- a handle connected to the first catheter;
- an anchor, wherein the anchor is transitionable between a straightened configuration, which can be disposed within the first lumen for transvascular delivery through an opening in a femoral vein to a cardiac valve, and a deployed configuration comprising at least two turns;
- a second catheter comprising a second lumen;
- a replacement valve, wherein the replacement valve comprises an expandable frame comprising a plurality of wires woven together and a valve body, wherein the valve body comprises multiple pieces of tissue that together form leaflets that can open to allow blood flow therethrough and close to prevent blood flow therethrough;
- wherein the replacement valve can transition from a collapsed configuration, in which the replacement valve can be disposed within the second lumen for transvascular delivery through the opening in the femoral vein to the cardiac valve, to an expanded configuration;
- and
- wherein the anchor can be transvascularly delivered through the first lumen of the first catheter to the cardiac valve, and the replacement valve is configured such that the replacement valve can be transvascularly delivered through the second lumen of the second catheter to the cardiac valve in the collapsed configuration and expanded to the expanded configuration inside the anchor and thereby secure the replacement valve and the anchor at the cardiac valve.
A system comprising:
- a catheter comprising a lumen, a proximal end, and a distal end;

- and
- wherein the replacement valve in the expanded configuration is configured to have a diameter smaller than a major axis of the cardiac valve, such that native commissural regions of the cardiac valve extend radially beyond the replacement valve.
A system comprising:
- a catheter comprising a lumen, a proximal end, and a distal end;
- a handle connected to the catheter at the proximal end of the catheter;
- an anchor, wherein the anchor is transitionable between a straightened configuration, which can be disposed within the lumen for transvascular delivery through an opening in a blood vessel to a cardiac valve of a heart, and a deployed configuration comprising at least two turns;
