1. An activation device, for applying energy to an implanted medical device, comprising:
- an outer elongate member having an outer elongate member distal end and an outer elongate member proximal end, and a lumen therebetween;
at least one inner elongate member having an inner elongate member distal end and in inner elongate member proximal end, wherein the at least inner elongate member is slidably inserted through the lumen of the outer elongate member;
wherein the at least one inner elongate member comprises a conducting member, situated within at least a portion of the inner elongate member, said conducting member effective to energetically couple an energy source to the implanted medical device;
wherein the conducting member further comprises an energy transfer element having a proximal end coupled to the conducting member, and a distal end that can be reversibly coupled to the implantable medical device; and
an engaging member, having a proximal end coupled to the distal end of the at least one inner elongate member, and a distal end effective to reversibly secure at least a portion of the activation device to at least a portion of the implantable medical device.

Abstract
An adjustable implantable medical device and adjustment device are described. In some embodiments, the adjustment device includes a lead with a distal end modified to permit better engagement and securement to the described implantable devices. In some embodiments, the contact of the lead is bent. Some embodiments include a coil that engages and secures the lead to the implantable device. Some embodiments include a suture line to aid in securing the lead to the implantable device.

17. A method, for applying energy to an implanted annuloplasty ring, the method comprising:
-
providing an activation device comprising; an outer elongate member having an outer elongate member distal end and an outer elongate member proximal end, and a lumen therebetween; an inner elongate member having an inner elongate member distal end and in inner elongate member proximal end, wherein the inner elongate member is slidably inserted through the lumen of the outer elongate member; a conducting member, situated within at least a portion of the inner elongate member, said conducting member effective to conduct energy from a energy source to the implanted medical device; an energy transfer element having a proximal end coupled to the conducting member, and a distal end that can be reversibly coupled to the implantable medical device; and an engaging member, having a proximal end coupled to the distal end of the at least one inner elongate member, and a distal end effective to reversibly secure at least a portion of the activation device to at least a portion of the implantable medical device; inserting at least a portion of the outer elongate member distal end, inner elongate member distal end, conducting member, energy transfer element, and engaging member, into an atrium of a patient'"'"'s heart at or near a base of an atrioventricular valve; engaging the activation device to the adjustable annuloplasty ring; and applying energy via the energy transfer element to the adjustable annuloplasty ring.
