17 Claims

1. An anchor system configured to secure an implantable device within a body, the anchor system comprising:

an anchor assembly comprising a first anchor element and a second anchor element;

an anchor drive mechanism;

a first actuator configured to engage the first anchor element to move the first anchor element independently of the second anchor element; and

a second actuator configured to engage the second anchor element, and engageable with the first actuator to allow the first actuator to move relative to the second actuator to move the first anchor element independently of the second anchor element, and to move together with the first actuator, while engaged with the first actuator, to move the second anchor element independently of the first anchor element.

14. An implantable device comprising:

a frame;

an anchor assembly mounted on the frame and comprising a first anchor element and a second anchor element;

an anchor drive mechanism;

a first actuator portion configured to engage the first anchor element; and

a second actuator portion configured to engage the second anchor element and the first actuator portion, and mounted to move together with the first actuator portion to move the second anchor element independently of the first anchor element while the second actuator portion is engaged with the first actuator portion, and to allow the first actuator portion to move the first anchor element independently of the second anchor element.
