Patent number: 10531869Abstract: 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 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 member and are movable to an expanded position when exposed from the outer member.Type: GrantFiled: May 16, 2015Date of Patent: January 14, 2020Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, Brian Tang, Jeffrey Peter Radziunas

Multi-lumen-catheter retractor system for a minimally invasive, operative gastrointestinal treatment
Patent number: 10517580Abstract: 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: GrantFiled: June 27, 2015Date of Patent: December 31, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy -
Publication number: 20190239872Abstract: Devices and methods for locking and/or cutting tethers during a tissue modification procedure are described. In some variations, a tether may be used to tighten or compress tissue by bringing two pieces or sections of the tissue together. The tether, which may be under tension, may be locked to maintain the tension, and excess tether may be severed, using one or more of the devices and/or methods. The devices and/or methods may be used, for example, in minimally invasive procedures.Type: ApplicationFiled: December 5, 2018Publication date: August 8, 2019Inventors: Eugene SERINA, Tenny C. CALHOUN, Stephen C. MEIER, Mariel FABRO, Tiffany Huynh MIRCHANDANI, John TO, Brian TANG

Publication number: 20170135567Abstract: 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: January 28, 2017Publication date: May 18, 2017Applicant: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy
