  • Endoluminal device with retractor system
    Patent number: 9125636
    Abstract: 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.

  • LAPAROSCOPIC INSTRUMENT AND TROCAR SYSTEMS AND RELATED SURGICAL METHOD
    Publication number: 20150190171
    Abstract: 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.

  • SYSTEM FOR A MINIMALLY-INVASIVE, OPERATIVE GASTROINTESTINAL TREATMENT
    Publication number: 20150157192
    Abstract: Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a first lumen, a first flexible tube positioned in the first lumen, and a second flexible tube positioned in the first lumen. The first lumen defines a first space configured and dimensioned to receive an endoscope. The first flexible tube and second flexible tube are fixed at a proximal portion and configured to float within the first lumen of the catheter. First and second flexible guides are slidably positioned within the first and second flexible tubes and dimensioned to receive a first instrument for axial movement therein, the first and second flexible guides movable to an angled position with respect to a longitudinal axis.
