Patent number: 10966701Abstract: Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a working space expanding system positioned at a distal portion, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body lumen. A tissue retractor having an inner member positioned within an outer guide member has a plurality of closed loops at a distal portion forming a petal-like structure. The loops are positioned in a collapsed position within the outer guide member and are movable to an expanded position when exposed from the outer guide member.Type: GrantFiled: May 6, 2016Date of Patent: April 6, 2021Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, Brian Tang, Jeffrey Peter Radziunas

Publication number: 20200305704Abstract: 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.Type: ApplicationFiled: June 15, 2020Publication date: October 1, 2020Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy

Publication number: 20200170499Abstract: 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.Type: ApplicationFiled: February 3, 2020Publication date: June 4, 2020Inventors: Gregory Piskun, John To, Brian Tang, Mariel Fabro, Oleg Shikhman

Patent number: 10595711Abstract: 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.Type: GrantFiled: February 14, 2015Date of Patent: March 24, 2020Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, Jeffrey Peter Radziunas, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy
