Claims183
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent a wall of a heart chamber so that the member draws portions of the chamber wall towards each other;
- and
- fixing the member in the position so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent a wall of an intact heart chamber so that the member draws portions of the chamber wall towards each other;
- and
- fixing the member in the position so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent a wall of an intact heart chamber so that the member alters a shape of the chamber during systole;
- and
- fixing the member in the position so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent a wall of an intact heart chamber so that the member reduces a radius of the chamber during systole;
- and
- fixing the member in the position so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent a wall of an intact heart chamber so that the member reduces a cross-sectional area of the chamber during systole;
- and
- fixing the member in the position so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent portions of a wall of a heart chamber so that the member alters a shape of the chamber during systole;
- and
- fixing the member in the position so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent portions of a wall of a heart chamber so that the member reduces a radius of the chamber during systole;
- and
- fixing the member in the position so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- placing a member in a position adjacent portions of a wall of a heart chamber so that the member reduces a cross-sectional area of the chamber during systole;
- and
- fixing the member in the position so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- applying a force at a point on a wall of a heart chamber to change a shape of the chamber during systole;
- and
- controlling the force such that a space remains between the wall proximate the point on the wall and an opposing wall of the chamber.
An apparatus for treating a heart, comprising:
- a member adapted to remain external a heart chamber and contact a wall of the heart chamber external to the chamber during systole, the member including a first portion for contacting a first portion of the chamber wall external to the chamber and a second portion for contacting a second portion of the chamber wall external to the chamber, wherein the member is adapted to alter a shape of the chamber.
An apparatus for treating a heart, comprising:
- a member adapted to remain external a heart chamber and contact a wall of the heart chamber external to the chamber, the member including a first portion for contacting a first portion of the chamber wall external to the chamber and a second portion for contacting a second portion of the chamber wall external to the chamber and opposite to the first portion of the chamber wall, wherein the first and second portions of the member are adapted to alter a shape of the chamber and draw interior portions of the chamber wall towards each other so that the interior portions of the chamber wall remain in a noncontacting relationship and all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- providing a member having a first portion and a second portion;
- and
- altering a shape of a heart chamber during systole by engaging a first portion of a wall of the chamber external to the chamber with the first portion of the member and engaging a second portion of the chamber wall external to the chamber with the second portion of the member.
A method for treating a heart, the method comprising the steps of:
- placing a member within an intact heart chamber so that the member alters a shape of the chamber;
- and
- fixing the member to the chamber so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member within an intact heart chamber so that the member reduces a radius of the chamber;
- and
- fixing the member to the chamber so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member within an intact heart chamber so that the member reduces a cross-sectional area of the chamber;
- and
- fixing the member to the chamber so that all interior parts of the chamber remain in direct fluid communication.
A method for treating a heart, the method comprising the steps of:
- placing a member within a heart chamber at portions of a wall of the chamber so that the member alters a shape of the chamber;
- and
- fixing the member to the chamber so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- placing a member within a heart chamber at portions of a wall of the chamber So that the member reduces a radius of the chamber;
- and
- fixing the member to the chamber so that the portions of the chamber wall remain in a non-contacting relationship.
A method for treating a heart, the method comprising the steps of:
- placing a member within a heart chamber at portions of a wall of the chamber so that the member reduces a cross-sectional area of the chamber;

A method for treating a heart, the method comprising the steps of:
- applying a force at a point on a wall of a heart chamber to change a shape of the chamber;
- and
- controlling the force such that a space remains between the wall proximate the point on the wall and an opposing wall of the chamber, wherein the force is applied and controlled by a member within the chamber and coupled to the point on the wall.
