Publication number: 20240082048Abstract: A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Applicant: SEBELA VLC LIMITEDInventors: Michael TAL, Bob KATZ, Mark James DEBISSCHOP, Peter WILSON, Oleg SHIKHMAN

Patent number: RE48684Abstract: 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: August 5, 2019Date of Patent: August 17, 2021Assignee: Boston Scientific Scimed, Inc.Inventors: Gregory Piskun, John To, Mariel Fabro, Brian Tang, Sergey Kantsevoy, Oleg Shikhman
