Patent ID: 8100916

Claim:
A system comprising an implantable device and an instrument for manipulating the implantable device, the instrument comprising: an engagement mechanism extending along an axis and selectively engaging a first portion of the implantable device, an alignment mechanism disposed on an exterior surface of the engagement mechanism, moveable relative to the engagement mechanism, and selectively engaging a second portion of the implantable device to align the second portion of the implantable device with the first portion of the implantable device, and a plurality of stops formed on the exterior surface of the engagement mechanism for defining multiple positions of the alignment mechanism on the exterior surface of the engagement mechanism, wherein the alignment mechanism includes a component to selectively engage the plurality of stops such that an engagement of the alignment mechanism with each of the plurality of stops prevents the alignment mechanism from moving along the axis of the engagement mechanism, the alignment mechanism rotating around the axis of the engagement mechanism at the positions where the alignment mechanism engages the plurality of stops; a counter-rotation mechanism disposed on an exterior surface of the alignment mechanism and rotating independently of the engagement mechanism and the alignment mechanism to selectively orientate the second portion of the implantable device relative to the first portion of the implantable device during operation of the implantable device, wherein the implantable device is inserted, adjusted and removed with the instrument.
