Patent number: 11583265Abstract: 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: December 16, 2019Date of Patent: February 21, 2023Assignee: Boston Scientific Scimed Inc.Inventors: Gregory Piskun, Brian Tang, Jeffrey Peter Radziunas

Patent number: 11471026Abstract: 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: November 19, 2019Date of Patent: October 18, 2022Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Gregory Piskun, Jeffrey Peter Radziunas, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy
