Patent number: 11839382Abstract: An assembly including a bougie and a sheath for use in performing a gastroplasty for dividing a stomach of a patient into a sleeve receiving food and a bypass portion. The bougie includes an elongated body having a segment being shaped to follow a lesser curve of the stomach, and an extension member being movable within the stomach for positioning a distal portion thereof away from a gastroesophageal junction of the stomach and to define a fluid passage between the sleeve and the bypass portion. The sheath has an elongated main lumen in which the bougie is inserted and the sheath is translatable along the bougie to selectively expose the extension member of the bougie to perform its guiding action, or hide the extension member to ensure secure displacement of the bougie within the stomach and along the oesophagus.Type: GrantFiled: August 24, 2022Date of Patent: December 12, 2023Assignee: BALLAST MEDICAL INC.Inventor: Michel Gagner

Patent number: 11510799Abstract: A gastroplasty method involves a staple line that terminates prior to reaching the gastroesophageal junction such that the bypassed portion of the stomach does not require resection. Additionally, bougies are taught that assist a physician in following the improved staple line of the present invention.Type: GrantFiled: September 19, 2019Date of Patent: November 29, 2022Assignee: BALLAST MEDICAL INC.Inventors: Michel Gagner, David J.

Publication number: 20210169486Abstract: A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.Type: ApplicationFiled: February 18, 2021Publication date: June 10, 2021Applicant: Ballast Medical Inc.Inventors: Michel Gagner, David J. Blaeser, Todd A. Krinke, Philip J. Haarstad

Publication number: 20200093585Abstract: A gastroenterologic sleeve is anchored within the digestive tract, without tissue-puncturing mechanisms, by providing anchoring mechanisms that utilize the inherent shape of the stomach to prevent sleeve migration. In at least two embodiments, the anchoring mechanism expands to conform to the interior stomach walls. In other embodiments, internal pessary rings are held in place at the gastroesophageal junction by an external band. A delivery device is provided for implanting the various device transesophageally.Type: ApplicationFiled: November 27, 2019Publication date: March 26, 2020Applicant: Ballast Medical Inc.Inventors: Michel Gagner, David J.
