Abstract
An instrument is provided for migration through a lumen of a tubular part. The instrument comprises a distal section including a distal bladder adapted to be inflated and deflated; a proximal section including a proximal bladder adapted to be inflated and deflated; and, an intermediate section including an intermediate bladder adapted to be inflated and deflated. A device is associated with the distal section. A coupler is interposed between the distal and intermediate sections for movably coupling the distal section to the intermediate section. A drive mechanism is coupled between the distal and intermediate sections for effecting movement of the distal section about the coupler. A controller is provided for selectively inflating and deflating the distal, proximal and intermediate bladders to effect migration of the distal, intermediate and proximal sections through the lumen.
