Systems and methods for guidance of a gastrointestinal device through a gastrointestinal tract are provided. A gastrointestinal guidewire is positioned through the gastrointestinal tract, by introduction of an introducing element into the gastrointestinal tract. One end of the gastrointestinal guidewire is attached to the introducing element, and the other end of the gastrointestinal guidewire is attached to an anchoring element, anchored to a location outside of the gastrointestinal tract. Movement of the introducing element through the gastrointestinal tract results in positioning of the guidewire through the gastrointestinal tract. The guidewire is then used as a scaffold to guide the gastrointestinal device, wherein the gastrointestinal device may be externally controlled. This allows for speeding up, slowing down, reversal and stopping of the gastrointestinal device during its descent through the gastrointestinal tract.

L'invention concerne des systèmes et des procédés pour le guidage d'un dispositif gastro-intestinal dans le tractus gastro-intestinal. Un fil-guide gastro-intestinal est positionné dans le tractus gastro-intestinal, par introduction d'un élément introducteur dans le tractus gastro-intestinal. Une extrémité du fil-guide gastro-intestinal est attachée à l'élément introducteur et l'autre extrémité du fil-guide gastro-intestinal est attachée à un élément d'ancrage, ancré à un emplacement à l'extérieur du tractus gastro-intestinal. Le mouvement de l'élément introducteur dans le tractus gastro-intestinal permet le positionnement du fil-guide dans le tractus gastro-intestinal. Le fil-guide est ensuite utilisé en tant qu'échafaudage pour guider le dispositif gastro-intestinal, le dispositif gastro-intestinal pouvant être commandé extérieurement. Ceci permet d'accélérer, de ralentir, d'inverser et de stopper le dispositif gastro-intestinal pendant sa descente dans le tractus gastro-intestinal.
