First Claim
Patent Images
1. A method of limiting diastolic expansion of the left ventricle, comprising positioning a prosthesis in a coronary venous pathway which surrounds at least a portion of the left ventricle;
- tensioning the prosthesis; and
attaching a proximal portion of the prosthesis to a distal portion of the prosthesis to form a closed loop for restraining expansion of the left ventricle.

Abstract
A left ventricle restriction device is designed to be transvenously advanced and deployed within the coronary sinus and in some embodiments other coronary veins. The device places tension on adjacent structures, reducing the diameter and/or limiting diastolic expansion of the left ventricle. This may be beneficial for patients with dilated cardiomyopathy.
