1. A device for securing an implant to body tissue, the device comprising:
- a cup defining a chamber and an opening leading to the chamber; and
a tissue piercing mechanism configured to rotate relative to the cup such that the tissue piercing mechanism rotates from a first position wherein the tissue piercing mechanism is substantially within the chamber to a second position wherein the tissue piercing mechanism lies substantially over the opening.

Abstract
Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning an implantable device outside and adjacent the heart wall such that the device alters the shape of the heart wall acting on the valve. The implantable device may alter the shape of the heart wall acting on the valve by applying an inward force and/or by circumferential shortening (cinching). The shape change of the heart wall acting on the valve is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example, to reduce regurgitation.

17. A device for improving heart valve function, the device comprising:
-
an elongate member having a first end and a second end; and
an anchoring member associated with each of the first end and the second end and configured to secure the device relative to the heart, wherein each of the anchoring members comprises a cup defining a chamber and an opening leading to the chamber; and
a tissue piercing mechanism configured to rotate relative to the cup such that the tissue piercing mechanism rotates from a first position wherein the tissue piercing mechanism is substantially within the chamber to a second position wherein the tissue piercing mechanism lies substantially over the opening. - View Dependent Claims (18, 19, 20, 21, 22, 23)

37. A delivery system for delivering an implant to a heart, the delivery system comprising:
-
a first catheter configured to simultaneously deliver to the heart an elongate member and a first anchor mechanism attached to a first end of the elongate member;
a second catheter configured to advance an intermediate component along the elongate member until the intermediate component is adjacent the first anchor mechanism; and
a third catheter configured to advance a second anchor mechanism along the elongate member to a position adjacent the intermediate component and on a side of the intermediate component opposite the first anchor mechanism. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

57. A device for improving heart valve function, the device comprising:
-
an elongate member having a first end and a second end;
an anchoring member associated with each of the first end and the second end and configured to secure the device relative to the heart such that the device provides a compressive force to an exterior portion of the heart sufficient to alter valve function; and
an intermediate component comprising a sleeve configured to be advanced over the elongate member and to be positioned between each anchoring member when the device is implanted in the heart, the sleeve being configured to distribute the force applied by the elongate member to the heart. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66)

84. A system for treating a heart valve, the system comprising:
-
an access device configured to access the pericardial space from a remote location, a portion of the access device being configured to be automatically inserted through the pericardium to a predetermined depth beyond the pericardium and to separate the pericardium from the epicardium; and
an implant configured to be delivered to the pericardial space and to be secured relative to the heart so as to exert a compressive force on the heart sufficient to alter valve function. - View Dependent Claims (85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100)
