Embodiment Construction
[0058] The various aspects of the invention to be discussed herein generally pertain to devices and methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other similar heart failure conditions. Each device of the present invention preferably operates passively in that, once placed in the heart, it does not require an active stimulus, either mechanical, electrical, or otherwise, to function. Implanting one or more of these devices alters the shape or geometry of the heart, both locally and globally, and thereby increases the heart's efficiency. That is, the heart experiences an increased pumping efficiency through an alteration in its shape or geometry and concomitant reduction in stress on the heart walls. In addition, the devices of the present invention may operate to assist in the apposition of heart valve leaflets to improve valve function.
[0059] The inventive devices and related methods offer numero...

A method for placing a splint assembly transverse a heart chamber includes providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to at least the first end. The method includes advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a wall surrounding the heart chamber and the second end extends through a second location of the heart chamber wall substantially opposite the first location. A deployable heart-engaging assembly is deployed such that it engages with a first exterior surface portion of the heart chamber wall adjacent the first location. The elongate member is secured with respect to the heart with a second heart-engaging assembly connected to the second end. The second heart-engaging assembly engages with a second exterior surface portion of the heart chamber wall adjacent the second location. A splint assembly includes an expandable heart-engaging assembly formed partially from portions forming the elongate member of the splint assembly. A delivery tool includes a tubular member configured to be advanced through vasculature structure and has a curved distal end.
Description
FIELD OF THE INVENTION [0001] The present invention pertains to devices for treating a failing heart and related methods for placing the devices. In particular, the invention pertains to splinting devices placed on the heart to reduce the radius of curvature and / or alter the geometry or shape of the heart to thereby reduce wall stress in the heart and improve the heart's pumping performance. The devices and methods of the present invention are directed toward endovascular techniques used to facilitate placement of the splinting devices on the heart. BACKGROUND OF THE INVENTION [0002] Heart failure is a common outcome in the progression of many forms of heart disease. Heart failure may be considered as the condition in which an abnormality of cardiac function is responsible for the inability of the heart to pump blood at a rate commensurate with the requirements of the metabolizing tissues, or can do so only at an abnormally elevated filling pressure. There are many specific disease ...
