Abstract
Gastrointestinal apparatus (10) is provided, including a guiding element (16) and an inflatable mechanical device (96), adapted to pull the guiding element (16) through a colon of a patient. A gastrointestinal tool (12) is shaped to define a bore (14) therethrough, and the guiding element (16) is adapted to pass through the bore (14). Other embodiments are also described.
Claims47
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, and
- be advanced distally through the colon in response to pressure from the fluid pressure source applied to an external surface of the piston head.
