Embodiment Construction

[0068] The teachings provided herein are generally intended for (in a minimally invasive manner) improved methods and devices for the treatment of gastrointestinal disorders through endoscopic surgery. The system includes an endoscopic surgical assembly formed by the system disclosed herein. The surgical component has a substantially symmetrically expanded reversibly expandable retractor, and the tool channel has a hyperbolic configuration described in detail below, which maximizes the distance from the tool to the target tissue to allow This maximizes the space for one or more tools and / or endoscopes that are all independently manipulated to visualize the target tissue in a minimally invasive manner and treat the target tissue from outside the patient. Among these improvements, the embodiments taught herein can provide an increase in the distance between the tool port and the target tissue to improve the independent operability and triangulation of each tool relative to the ta...

Abstract

A system for performing minimally invasive procedures in a body lumen of a patient including 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. The first flexible tube is movable through the second lumen and has a distal portion including a first curve extending in a first direction with respect to the longitudinal axis and a second curve extending in a second different direction with respect to the longitudinal axis. A retractor system is positioned at a distal portion of the catheter and is movable from a non-expanded insertion position to an expanded position forming an expanded cage to form a larger working space. The distal portion of the first flexible tube is movable within the expanded cage.
