摘要： 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.

摘要： Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one-or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.

摘要： Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.
