Patent ID: 7601156

Claim:
A bone distraction device, comprising: a first mount configured to be subcutaneously coupled to a first portion of a bone, wherein the first mount is contoured in an arc of at least π/3 radians to accommodate the circumference of the bone; a second mount configured to be subcutaneously coupled to a second portion of the bone, wherein the second mount is contoured in an arc of at least π/3 radians to accommodate the circumference of the bone; three or more guide rods, wherein a first end of each guide rod is coupled to the first mount, and wherein each of the guide rods is coupled to the second mount; and a distractor coupled to the first and second mounts, wherein the distractor is configured to subcutaneously move the second mount relative to the first mount during use such that the second portion of the bone is distracted from the first portion of the bone, wherein the distractor comprises an output shaft, the output shaft configured to subcutaneously rotate, and when rotated, the output shaft is configured to move the second mount relative to the first mount; and a transcutaneous actuator configured to transcutaneously engage the output shaft such that turning the transcutaneous actuator rotates the output shaft while the output shaft is subcutaneously disposed.
