Abstract: The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to systems and methods for en bloc resection of malignant and pre-malignant lesions and/or tumors within the gastrointestinal (GI) tract. More specifically, the present disclosure relates to systems and methods for delivering an expandable scaffold between tissue layers (e.g., between the muscularis and submucosa layers) to elevate and stabilize the lesion or tumor for fast and efficient resection.

Abstract: A rapid exchange catheter comprises a guide wire lumen including a substantially sealed portion in which a lumen wall extends around an entire periphery thereof and a channel portion including a channel opening the lumen to an exterior of the catheter, wherein a width of the channel is less than a maximum width of the channel portion. A guide wire ramp extends into the channel portion, with the ramp extending further into the lumen of the channel portion as a distal end of the ramp is approached.
