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.

Dependent claims

A system, comprising:

a flexible catheter having a proximal region and a distal region, a first flexible tube and a second flexible tube;
the first flexible tube having a first channel extending through a longitudinal axis thereof, the first channel configured and dimensioned to removably receive a first endoscopic tool therein;
a distal portion of the first flexible tube movable to a curved position with respect to the longitudinal axis when extended distally beyond the distal region of the flexible catheter;
the second flexible tube having a second channel extending through a longitudinal axis thereof, the second channel configured and dimensioned to removably receive a second endoscopic tool therein;
a distal portion of the second flexible tube movable to a curved position with respect to the longitudinal axis when extended distally beyond the distal region of the flexible catheter;
wherein the curved position of the first flexible tube includes a first curved portion extending away from the longitudinal axis thereof, and a second curved portion extending toward the longitudinal axis thereof;
and
wherein the curved position of the second flexible tube includes a first curved portion extending away from the longitudinal axis thereof, and a second curved portion extending toward the longitudinal axis thereof.

A system, comprising:

a flexible catheter having a proximal region and a distal region, a first flexible tube and a second flexible tube;
the first and second flexible tubes removably insertable through the proximal region of the flexible catheter;
the first and second flexible tubes independently rotatable and axially movable within the flexible catheter;
the first flexible tube having a first channel extending through a longitudinal axis thereof, the first channel configured and dimensioned to removably receive a first endoscopic tool therein;
a distal portion of the first flexible tube movable from a straight configuration to a curved position relative to the longitudinal axis when extended distally beyond the distal region of the flexible catheter;
the second flexible tube having a second channel extending through a longitudinal axis thereof, the second channel configured and dimensioned to removably receive a second endoscopic tool therein;
a distal portion of the second flexible tube movable from a straight configuration to a curved position relative to the longitudinal axis when extended distally beyond the distal region of the flexible catheter;
wherein the curved position of the first flexible tube includes a first bent portion extending away from the longitudinal axis thereof, and a second bent portion extending toward the longitudinal axis thereof;
and
wherein the curved position of the second flexible tube includes a first bent portion extending away from the longitudinal axis thereof, and a second bent portion extending toward the longitudinal axis thereof.
