Balloon-tipped endoscopic system

A method of delivery using a multi-luminal delivery system, the system comprising:

• an outer catheter comprising a wall that encloses an outer lumen;
• an inner catheter movable disposed within the outer lumen and having an inner lumen;
• a balloon-tipped catheter movable disposed within the inner lumen having a distal end comprising a balloon tip and a proximal end, wherein the balloon tip can be expanded to contact the wall of the outer catheter to provide a seal to prevent bodily fluids from entering the outer lumen;
• and
• the deployable device located about the inner catheter;
• said method comprising:
• introducing the system into an endoluminal vessel until the balloon tip reaches a desired location;
• deflating the balloon tip;
• placing the deflated balloon tip within the inner lumen of the catheter;
• and
• deploying the deployable device by manipulating the outer catheter relative to the inner catheter such that the deployable device is distal to the outer catheter.

A multi-luminal system comprising:

• an outer catheter comprising a wall that encloses an outer lumen;
• a first inner catheter movably disposed within the outer lumen and having an inner lumen;
• a balloon-tipped catheter movably disposed within the inner lumen and having a distal end comprising a balloon tip and a proximal end, wherein the balloon tip can be expanded to contact the wall of the outer catheter to provide a seal to prevent bodily fluids from entering the outer lumen;
• a second inner catheter having a lumen and disposed within the outer lumen,
• a tissue collecting mechanism disposed within the lumen of the second inner catheter;
• and
• wherein the first inner catheter and the balloon-tipped catheter have a common center different than the second inner catheter.
