1. A method for reducing ventricular volume, comprising:
- inserting a catheter into a ventricle of a patient'"'"'s heart;
deploying a tensile member from a leading end of said catheter;
attaching said tensile member to the patient'"'"'s heart; and
exerting tension on said tensile member to draw walls of the patient'"'"'s heart towards one another to reduce the volume of at least one ventricle of the patient'"'"'s heart.

Abstract
A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient'"'"'s hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.

29. A method for reducing ventricular volume, comprising:
-
inserting a catheter into a ventricle of a patient'"'"'s heart; deploying a tensile member from a leading end of said catheter; attaching said tensile member to the patient'"'"'s heart so that said tensile member is contained completely within the patient'"'"'s heart and does not protrude therefrom; and exerting tension on said tensile member to draw walls of the patient'"'"'s heart towards one another to reduce the volume of at least one ventricle of the patient'"'"'s heart. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A surgical method for assisting cardiac function, comprising:
-
inserting a device into a patient; applying said device to a portion of the patient'"'"'s heart so as to compress and at least partially close a portion of at least one ventricle of the heart, said device including a wire provided at a free end with at least one anchoring mechanism, the applying of said device to the portion of the patient'"'"'s heart including; inserting a catheter into a ventricle of the patient'"'"'s heart; ejecting said free end of said wire from said catheter into the patient'"'"'s myocardium so that said free end and said at least one anchoring mechanism are embedded in the myocardium, surrounded thereby; and exerting tension on said wire to pull walls of the patient'"'"'s heart towards one another so as to compress said portion of said at least one ventricle of the heart. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)
