Systems and methods for forming an anastomosis between two adjacent walls of a digestive tract are provided. The system includes first and second magnetic implants comprising first and magnetic bodies, respectively. Each of the first and magnetic bodies comprises a tissue-oriented surface and a lumen-oriented surface, and defines a through-hole extending between the tissue-oriented surface and the lumen-oriented surface. The first and second magnetic implants are configured to magnetically couple to each other through the two adjacent walls of the digestive tract with the through-holes being at least partially superposable to each other to compress an annular portion of the two adjacent walls therebetween. The first and second magnetic implants can include various features such as being configured to selectively adopt a delivery or an anastomosis configuration, being dimensioned to maintain a preliminary passageway between the two adjacent walls within their outer periphery, being electrically insulated, etc.

Magnetic implants having through-holes for forming an anastomosis

Systems and methods for forming an anastomosis between two adjacent walls of a digestive tract are provided. The system can include first and second magnetic implants configured to magnetically couple through two adjacent walls of the digestive tract to compress a portion of the two adjacent walls therebetween and form a necrotic area that becomes surrounded by a scarred edge following a healing time period. The magnetic implant can include a magnetic member and a non-magnetic member. The system can include a retention member extending outwardly from a corresponding one of the first and second magnetic implants, the retention member being configured to retain the magnetic implants in position and prevent passage thereof through the necrotic area during the healing time period, and to maintain an engagement between the magnetic member and the non-magnetic member during the healing time period and enable disengagement thereof following the healing time period.

Anastomosis formation with magnetic devices having bioresorbable retention member

There is provided a partitioning device to partition a hollow organ of a digestive tract of a patient in the context of digestive surgeries. The partitioning device includes a magnet assembly implantable into an abdominal cavity of the patient, the magnet assembly including a plurality of magnet elements flexibly connected in series. The magnet assembly is configured to be positioned extraluminally around at least a portion of an outer surface of the hollow organ to magnetically couple opposite magnet elements together to compress opposite walls of the hollow organ therebetween until opposite walls of the hollow organ are fused together, thereby partitioning the hollow organ. The magnet elements can be received in a housing and have various shapes. The partitioning device can include additional features such as a leading elongated member that can aid in the positioning of the partitioning device, and a trailing elongated member.

Anastomosis formation device

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.

Enhanced techniques for insertion and extraction of a bougie during gastroplasty

Suture materials for producing medical devices are provided. The suture materials can include natural fibers, and can be suitable for making multifilament sutures and surgical meshes comprising multifilament sutures as examples of medical devices. The multifilament suture can include a plurality of filaments combined together according to a twined pattern, and at least one filament of the plurality of filaments can include natural fibers, synthetic fibers, or mineral-based fibers. A suture device can include the multifilament suture combined with a suture needle. The multifilament suture can be coated with a biocompatible coating, such as a bioactive agent, and/or include a first set of filaments that includes natural fibers and a second set of filaments that includes natural fibers that are different from the natural fibers of the first set of filaments, synthetic fibers or mineral-based fibers, for instance.

Natural fibers having absorbable and hydrophobic properties for making surgical sutures and surgical meshes

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.

Activable bougie for performing gastroplasty

A positioning wand for assisting in positioning at least one of a first magnetic implant and a second magnetic implant configured for forming an anastomosis between two adjacent walls of a digestive tract of a patient is provided. The positioning wand can include an elongated member sized and configured to be inserted into an abdominal cavity of the patient, and a distal tip provided at a distal end of the elongated member. The distal tip can include a guide magnet configured to magnetically couple with the at least one of the first and second magnetic implants through a wall of the digestive tract to position the at least one of the first and second magnetic implants to a desired site of the anastomosis. The distal tip can be configured to be moveable in response to a contact pressure upon contact with the wall of the digestive tract.

Devices and methods for assisting magnetic compression anastomosis

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.
