Heart wall tension reduction apparatus and method

A method of disposing a heart wall tension reduction apparatus on a human heart having a plurality of chambers, comprising the steps of:

• providing a heart wall tension reduction apparatus including an elongate compression member having first and second ends;
• first and second elongate lever members, the first lever member extending from the first end of the compression member, and the second lever member extending from the second end of the compression member;
• a tension member extending between the first and second lever members;
• and
• extending the tension member through at least one chamber of the human heart.

A heart wall tension reduction apparatus, comprising:

• a rigid elongate frame member having a first end and a second end;
• a first cantilever member disposed at the first end of the frame member;
• and
• a second cantilever member disposed at the second end of the frame member.

A method of placing a heart wall tension reduction apparatus on a human heart having a plurality of chambers, comprising the steps of:

• extending a hollow needle through at least one chamber of the heart such that each end of the needle is external to the heart;
• providing a tension member having first and second ends;
• connecting the second end of the tension member to a first atraumatic pad;
• advancing the tension member trough the needle from one end of the needle to the other;
• further advancing the tension member until the first atraumatic pad engages the heart and the first end of the tension member is external to the at least one chamber;
• and
• connecting the first end of the tension member to a second atraumatic pad such that the second atraumatic pad engages the heart.

A method of placing a heart wall tension reduction apparatus on a heart having a plurality of chambers, comprising the steps of:

• extending a guide member through at least one chamber of the heart such that each end of the guide member is external to the chamber;
• providing a tension member having at least one lumen extending therethrough;
• extending a portion of the guide member through the lumen;
• advancing the tension member on the guide member such that a first end of the tension member is disposed to one side of and external to the at least one chamber, and a second end of the tension member is disposed to an opposite side of and external to the at least one chamber;
• and
• connecting a first atraumatic pad to the first end and a second atraumatic pad to the second end of the tension member.

A method of placing a heart wall tension reduction apparatus on a heart having a plurality of chamber comprising the steps of:

• extending a needle having a flexible tension member releasably connected thereto through at least one chamber of the heart such that opposite ends of the tension member are external to the chamber and exposed on opposite sides thereof;
• removing the needle from the tension member;
• and
• connecting a first atraumatic pad to one end of the tension member and a second atraumatic pad to the opposite end of the tension member.

A heart wall tension reduction apparatus, comprising;

• a first generally linear elongate tension member for drawing at least two walls of a chamber of the heart toward each other, the tension member having two oppositely disposed ends;
• a plurality of anchors, including an elongate anchor having a first end and a second end, one end of the first tension member being connected to the first end of the elongate anchor, and the opposite end of the first tension member being connected to one anchor to secure the tension member to the heart;
• and
• a second generally elongate tension member for drawing at least two walls of a chamber of the heart toward each other, the second tension member having two oppositely disposed ends, wherein one end of the second tension member is connected to the second end of the elongate anchor and the opposite end of the second tension member is connected to one of the anchors such that where the tension members are disposed between the anchors, the tension members are spaced from each other.
