1. A method for improving cardiac function, comprising:
- inserting a flexible leading end of a catheter into a patient'"'"'s heart;
inserting a compressive device into the patient'"'"'s heart through said catheter; and
after the inserting of said compressive device into the patient'"'"'s heart, operating said compressive device to bring opposite walls of only one ventricle of the patient'"'"'s heart into at least approximate contact with one another to thereby constrict and close off a lower portion of said one ventricle of the patient'"'"'s heart.

Abstract
A cardiac insert or implant is deployed in a patient'"'"'s heart so as to reduce ventricular volume, thereby improving cardiac function. The insert or implant may be a compressive device such as a tensile member inserted into the patient'"'"'s heart, and thereafter operated or deployed to bring opposite walls of a ventricle of the patient'"'"'s heart into at least approximate contact with one another to thereby constrict and close off a lower portion of that ventricle. The compressive device or tensile member is insertable into the patient heart via a catheter threaded through the patient'"'"'s vascular system and into the patient'"'"'s heart.

8. A method for improving cardiac function, comprising:
-
inserting a tensile member into a patient; and deploying said tensile member in the patient'"'"'s heart so as to effectively constrict and substantially close off a lower or apical portion only of only a right ventricle of the patient'"'"'s heart, thereby reducing the volume of the right ventricle and only the right ventricle of the patient'"'"'s heart. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for reducing ventricular volume, comprising:
-
inserting a leading end portion of a catheter through part of a patient'"'"'s vascular system and into a ventricle of the patient'"'"'s heart; deploying a cardiac insert or implant from said leading end portion of said catheter; and disposing said cardiac insert or implant in the patient'"'"'s heart to bring opposite walls of only a right ventricle of the patient'"'"'s heart into contact with one another and thereby close off a lower portion of the right ventricle to reduce the volume of only the right ventricle of the pateint'"'"'s heart.
