Abstract:
A distraction device for controlled movement of at least two sections of regenerative living tissue, such as bone, within the body of a living thing relative to each other to foster reshaping of the living tissue, the device comprising:a first jack unit comprising a first linear control jack and a first angular control jack, wherein the first linear control jack has a first extendable member adapted for attachment to one of the sections of living tissue, said first angular control jack being adapted for pivoting movement of the first extendable member within a first plane and said first linear control jack being adapted for movement of the first extendable member along a line within said first plane; a second jack unit comprising a second linear control jack, wherein the second linear control jack has a second extendable member adapted for attachment to the other of the sections of living tissue, said second linear control jack being adapted for extension of the second extendable member; an actuator for actuating extension of the extendable members and pivoting movement of the first extendable member to move the sections of living tissue apart for controlled regeneration of tissue between the sections; and a joint interconnecting the first and second jack units, the joint being adapted to permit orientation of the first and second jack units relative to each other, the jack units and joint being sized and shaped for implantation entirely within the body for living tissue reshaping with movement of the device confined entirely within the body.
