First Claim
Patent Images
1. Gastrointestinal (GI) apparatus comprising:
- a guiding element;
an inflatable mechanical device, adapted to pull the guiding element through a colon of a patient;
a gastrointestinal tool shaped to define a bore therethrough, the guiding element passing through the bore; and
a biologically-compatible-fluid pressure source,wherein the inflatable mechanical device comprises a piston head coupled to a distal portion of the guiding element and adapted to;
be inflated so as to form a pressure seal with a wall of the colon when the guiding element is in the colon, andbe advanced distally through the colon in response to pressure from the fluid pressure source applied to an external surface of the piston head.
