Abstract: Systems and methods for positioning a magnetic implant for forming an anastomosis at a target location in a digestive tract of a patient are provided. The system can include first and second magnetic implants configured to magnetically couple to each other through two adjacent walls of the digestive tract at a desired site of the anastomosis 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 system further can further include a positioning marker positionable at a target location corresponding to a first location on one side the desired site of the anastomosis for the first magnetic implant, the positioning marker being configured to intercept the first magnetic implant at the target location once swallowed by the patient.

Abstract: 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.

Abstract: There is provided a clamping device and method to resection an inwardly protruding portion present in a hollow organ of a patient, for example during bariatric surgeries, an appendectomy, a resection or excision surgery, etc. The clamping device includes a magnet assembly implantable into a lumen of the hollow organ of the patient. The magnet assembly has magnet elements arranged in two zones and is configured to be positioned around a base of the inwardly protruding portion. Opposing magnet elements are magnetically coupled together to compress opposite walls of the base therebetween until the walls are fused together, thereby partitioning the inwardly protruding portion from the remainder of the organ. The inwardly protruding portion can be pulled into the lumen of the hollow organ prior to the clamping device being positioned around the base. The inwardly protruding portion can be removed from the hollow organ to resection the organ.

Abstract: 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.

Abstract: 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.

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.
