Abstract
A bone transport system includes a nail having a proximal end and a distal end, the proximal end configured for securing to a first portion of bone, the distal end configured for securing to a second portion of bone. The system includes a housing having a wall with a longitudinal opening extending a length along a portion thereof. The system further includes a transport sled having a length that is shorter than the length of the longitudinal opening, the transport sled configured for securing to a third portion of bone, the transport sled further configured to be moveable along the longitudinal opening. The system further includes a magnetic assembly disposed within the nail and configured to be non-invasively actuated by a moving magnetic field, wherein actuation of the magnetic assembly moves the transport sled along the longitudinal opening. The system further includes a ribbon extending on opposing sides of the transport sled and substantially covering the longitudinal opening.
