摘要：
Multi-luminal endoscopic systems for sterilely delivering deployable devices. The system comprises an outer catheter comprising a distal portion and a wall that encloses an outer lumen an 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 portion and a proximal portion, wherein the distal portion of the balloon- tipped catheter comprises a balloon a deployable device within the outer lumen an invertible sleeve within the outer lumen with a first section attached to the distal portion of the outer catheter and a second section attached to a push mechanism that is proximal to the deployable device and wherein the balloon is expandable to contact the invertible sleeve to provide a seal to prevent bodily fluids from entering the outer lumen.
