A delivery device for delivering a gastrointestinal device into a gastrointestinal tract of a patient, said gastrointestinal device comprising a porous structure configurable between a compressed pre-deployment configuration and an expanded post-deployment configuration, an anti-migration collar proximate a distal end of said porous structure, and an elongate sleeve coupled to the distal end of said porous structure, said delivery device comprising: a flexible outer catheter having a proximal end, a distal end, and a lumen; a flexible inner catheter having a proximal end, a distal end, and a lumen configured to slidably receive a guide wire, wherein said inner catheter is positioned coaxially and is configured to be slidably movable within the lumen of said outer catheter; wherein said outer catheter is configured to be retracted in a proximal direction over said inner catheter while maintaining said inner catheter in place to expose said gastrointestinal device from said distal end of said delivery device, and further comprising a first handle attached to the proximal end of said inner catheter and having a proximal end, a distal end, and a lumen configured to slidably receive said guide wire; a second handle attached to the proximal end of said outer catheter and having a proximal end, a distal end, and a lumen configured to slidably receive said inner catheter, wherein, prior to delivery of said intragastric device, a proximal portion of said inner catheter positioned between said first and second handles is exposed and not covered by said outer catheter; characterised by further comprising: an elongate flexible pilot component having a proximal end, a distal end and a length having a variable stiffness, said pilot component comprising a distal spherical component and a proximal spherical component and extending from said distal end of said inner catheter; a first stopping mechanism removably attached to said exposed portion of said inner catheter; and a second stopping mechanism removably attached to said exposed portion of said inner catheter and positioned proximal to said first stopping mechanism; wherein said first and second stopping mechanisms are configured to be sequentially removed from said inner catheter as said outer catheter is retracted. a flexible outer catheter having a proximal end, a distal end, and a lumen; a flexible inner catheter having a proximal end, a distal end, and a lumen configured to slidably receive a guide wire, wherein said inner catheter is positioned coaxially and is configured to be slidably movable within the lumen of said outer catheter; wherein said outer catheter is configured to be retracted in a proximal direction over said inner catheter while maintaining said inner catheter in place to expose said gastrointestinal device from said distal end of said delivery device, and further comprising a first handle attached to the proximal end of said inner catheter and having a proximal end, a distal end, and a lumen configured to slidably receive said guide wire; a second handle attached to the proximal end of said outer catheter and having a proximal end, a distal end, and a lumen configured to slidably receive said inner catheter, wherein, prior to delivery of said intragastric device, a proximal portion of said inner catheter positioned between said first and second handles is exposed and not covered by said outer catheter; an elongate flexible pilot component having a proximal end, a distal end and a length having a variable stiffness, said pilot component comprising a distal spherical component and a proximal spherical component and extending from said distal end of said inner catheter; a first stopping mechanism removably attached to said exposed portion of said inner catheter; and a second stopping mechanism removably attached to said exposed portion of said inner catheter and positioned proximal to said first stopping mechanism; wherein said first and second stopping mechanisms are configured to be sequentially removed from said inner catheter as said outer catheter is retracted.
