Abstract:
1. A system for performing minimally invasive procedures in a body lumen of a patient, the system comprising: a flexible catheter having a first lumen configured and dimensioned to receive an endoscope therethrough and a second lumen configured and dimensioned to receive a first flexible tube therethrough; a first flexible tube movable through the second lumen, the first flexible tube having a first channel extending therethrough configured and dimensioned to receive a first endoscopic tool for axial movement therein, the first flexible tube having a longitudinal axis and a tube distal portion movable to an angled position with respect to the longitudinal axis, the first flexible tube slidable axially within the second lumen; a body lumen reshaping system positioned at a distal portion of the catheter, the reshaping system including first and second flexible elements movable from a non-expanded insertion position to an expanded position forming an expanded cage to reshape the body lumen to an asymmetric shape to form an asymmetric working space, the distal portion of the first flexible tube movable within the expanded cage; and a proximal coupler to retain a proximal portion of the first and second flexible elements and a distal coupler to retain a distal portion of the first and second flexible elements, wherein the proximal and distal couplers include a lumen dimensioned to receive the endoscope therethrough when the catheter is backloaded over the endoscope.
