Abstract

Tissue restraining systems and devices as well as methods of using these devices are disclosed herein. According to aspects illustrated herein, there is provided a tissue restraining device that may include a first anchor having one or more contact points along a portion of the first anchor in a spaced relation to one another. The tissue restraining device may also include a second anchor for placement in a substantially opposing relation to the first anchor. A restraining matrix may extend from the contact points of the first anchor to the second anchor.

Claims

1. A method of treatment of a prolapsed mitral valve comprising:

embedding a second anchor into a tissue in a left ventricle;

deploying a first anchor in a left atrium, the first anchor having a connection point at the first end of the first anchor a first arm and a second arm situated adjacent to the first arm and extending in a same direction as the first arm, the first arm and the second arm both extending in the longitudinal direction of the first anchor from the connection point between the first end and the second end of the first anchor, the first arm and the second arm being biased toward each other;

pinching a common wall between the coronary sinus and the left atrium between the first arm and the second arm thereby securing the first anchor to the common wall;

extending a restraining matrix from the first anchor over the mitral valve and into the left ventricle to connect the restraining matrix to the second anchor such that the restraining matrix is draped over the mitral valve; and

adjusting the restraining matrix to correct a prolapsing segment of the mitral valve.

2. The method of claim 1, wherein, in the step of deploying, the first arm is deployed in the coronary sinus and the second arm is deployed in the left atrium to secure the first anchor to the common wall between the coronary sinus and the left atrium.

3. The method of claim 2, wherein, in the step of deploying, the first arm is advanced over a coronary sinus guidewire and the second arm is advanced over a transeptal guidewire such that the first arm is deployed in the coronary sinus and the second arm is deployed in the left atrium.

4. The method of claim 1, wherein in the step of adjusting, the restraining matrix is formed by one or more restraining chords.

5. The method of claim 1, wherein in the step of adjusting, the restraining matrix is adjusted by individually adjusting the restraining chords.

6. The method of claim 1 further including a step of coupling a sheath attached to a proximal end of the restraining matrix to the first anchor to secure the proximal end of the restraining matrix in the left atrium.

7. The method of claim 1, wherein the mitral valve is accessed via a minimally invasive approach.

8. The method of claim 7, wherein the mitral valve is accessed via a percutaneous approach.

9. The method of claim 1, wherein the mitral valve is accessed via an open heart approach.
