1. A device for improving the function of a heart, the device comprising:
- an elongate member configured to be positioned transverse a chamber of the heart; and
a release mechanism connected to the elongate member, the release mechanism being configured to releasably engage with each of a plurality of anchoring members having differing configurations to releasably attach the elongate member to each of the plurality of anchoring members one at a time.

Abstract
Devices, systems and methods for improving the function of a valve of a heart by implanting the device adjacent the valve such that the device indirectly applies a force to the valve and increases coaptation of the leaflets, or otherwise improves valve function. The device may be implanted in a position that does not directly contact the valve structures. The force may be applied to a wall of the heart, and the force may be an inward force applied to two walls of the heart, such as the left ventricular free wall and the ventricular septum, or the left ventricular free wall and the right ventricular free wall, to improve mitral valve function.

25. A method for improving the function of a heart, the method comprising:
-
providing a plurality of anchoring members having differing configurations;
providing an elongate member and a release mechanism connected to the elongate member, the release mechanism being configured to releasably engage with each of the plurality of anchoring members;
selecting one of the plurality of anchoring members;
positioning the elongate member transverse a chamber of the heart; and
engaging the release mechanism with the selected anchoring member so as to releasably attach the elongate member to the selected anchoring member.

26. A method of delivering a device to be positioned relative to a heart chamber, the method comprising:
-
providing an elongate member having a first end and a second end, the second end having an expandable anchoring member attached thereto;
advancing the first end of the elongate member through a first heart wall, a septal wall, and a second heart wall substantially opposite the septal wall such that the elongate member extends substantially transverse a heart chamber; and
expanding the expandable anchoring member such that the expandable anchoring member prevents the second end of the elongate member from being able to pass through the septal wall and into the heart chamber. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A device for securing an elongate member in a position transverse at least one heart chamber, the device comprising:
an anchor assembly configured to be secured to the elongate member, the anchor assembly having a collapsed configuration and an expanded configuration and comprising a first arm, a second arm, and at least one biasing member connecting the first arm and the second arm, wherein, in the absence of external force, the biasing member is configured to exert a biasing force on the first arm and the second arm such that the anchor assembly is in the expanded configuration. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. An alignment device comprising:
-
an arm; and
a tissue engaging member configured to engage a tissue surface connected to the arm, the tissue engaging member comprising a cover defining a cover opening, and a rotatable insert defining a plurality of openings configured to be individually aligned with the cover opening by rotating the insert with respect to the cover, wherein, when the cover opening and one of the plurality of openings are aligned, the cover opening and one of the plurality of openings are configured to receive a needle assembly. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57)
