First Claim
Patent Images
1. A method for improving cardiac function, comprising the steps of:
- inserting a tether device into a patient; and
inserting said tether device through the apex of the patient'"'"'s heart and into the left ventricle of the patient'"'"'s heart; and
attaching a first papillary muscle anchor of said tether device to a first papillary muscle within said left ventricle; and
attaching a second papillary muscle anchor of said tether device to a second papillary muscle of the patient'"'"'s heart; and
wherein said first papillary muscle anchor and said second papillary muscle anchor are joined by a tether member so as to reduce the volume of the left ventricle.

13. A medical device for improving cardiac function or reducing ventricular volume, comprising:
- a cannula having a tethering device disposed therein;
said cannula having a trocar for piercing the apex of the patient'"'"'s heart and a leakage control valve/sleeve;
said tethering device comprising at least one first papillary muscle anchor for attaching to a first papillary muscle within said left ventricle and at least one second papillary muscle anchor for attaching to a second papillary muscle of the patient'"'"'s heart;
said tethering device further comprising a tether member for joining said first papillary muscle anchor to said second papillary muscle anchor so as to reduce the left ventricular volume of the patient. - View Dependent Claims (14, 15, 16)
