The invention relates to a method, system, and device for protecting an anastomosis between at least two lumens of a body. The method includes identifying a requirement of creating the anastomosis between a first lumen and a second lumen of the at least two lumens of the body. The method further placing a tube made up of a biodegradable material, at a level of the anastomosis, inside the at least two lumens during the anastomosis or after the anastomosis, through a delivery system. It should be noted that the tube covers the anastomosis. The method further includes securing the tube at the level of the anastomosis to seal the tube against walls of the at least two lumens; and protecting the anastomosis by preventing a contact between the anastomosis and luminal contents associated with the at least two lumens of the body, through the tube.

A method is described for shearing a tissue wall between a first cavity and an adjacent second cavity in a human or animal body. The tissue wall has a periphery forming an edge of an opening between the first cavity and the second cavity. A first member is placed into the first cavity, such that the first member is adjacent the wall. A second member is placed in the second cavity, proximate the first member. The first and second members have materials which magnetically attract one another. The first member and the second member are placed such that there is magnetic attraction between the first member and the second member through the wall and thereby compress an overlapping portion of the wall to create pressure necrosis. The first member and the second member are connected by a thread, wherein the thread extends over the edge of the opening.

A compression assembly for use in compressing tissue comprising a first portion which includes a first compression element and a second portion which comprises a second compression element, at least one support element, at least one spring stopper element, and at least one spring element. Typically the spring stopper element is formed of a bio-degradable or otherwise functionally controllable material. The at least one spring element is in compressive force contact with the second compression element and the tissue to be joined is positioned between the first and second compression elements. A plurality of needles on one of the support elements is operative to pierce the tissue and the first portion of the assembly, holding the first compression element to the second portion of the assembly. The invention is appropriate for joining severed tissue in anastomosis procedures or closing natural or surgically produced tissue perforations.

Methods and apparatus for creating an anastomosis or fistula between the gallbladder and an adjacent organ are disclosed. First, a parent magnet, typically a permanent magnet, is deployed in the stomach, small intestine, or another organ adjacent to the gallbladder, and a mating daughter material is deployed in the gallbladder in order to create a magnet-compression anastomosis. The gallbladder may then be ablated or otherwise functionally inactivated through the anastomosis. Another aspect of the invention relates to an all-in-one surgical kit that contains all the necessary specialized tools for a surgeon to perform the procedure.

Magnetic anastomosis devices constructed from magnetic segments coupled together with members that help the devices spontaneously transform from a linear delivery configuration to a polygonal deployment configuration. When two devices are joined together over tissue(s), the compressive force causes the tissue(s) to necrose and form an anastomosis. By altering the arrangement of the magnetic poles of the magnetic segments in the devices, the magnetic interaction between paired devices can be altered. This property gives surgeons flexibility in choosing how much attractive force the devices will experience during a procedure.

The present disclosure provides modular magnetic anastomosis devices that can be implemented in digestive surgery or in any circumstance of anastomosis between adjacent organs or two hollow viscera. The device is minimally invasive and easily and quickly delivered using laparoscopic or endoscopic procedures.

An apparatus for joining organ wall portions of first and second hollow organs, including first and second connectors, wherein the first and second connectors are magnetically attracted to one another. A device for delivering and deploying the first and second connectors to portions of the first and second hollow organs can be provided, wherein the device is configured and dimensioned to axially align the first and second connectors for performing circular anastomosis of the first and second hollow organs.

Devices and methods are used to modify a metabolic pathway of a digestive system by creating a pathway within the intestinal tract through an anastomosis between a proximal location within the intestinal tract and a distal location within the intestinal tract. In some examples, the small intestine has a first initial length and the created pathway defines a second length of the intestinal tract that is approximately ten to seventy percent of the first initial length of the small intestine.

A method and devices that endoscopically create an anastomosis between two sections of the digestive tract, thereby allowing at least some chyme to bypass a section of the digestive tract while, optionally, the remaining chyme passes through the entire tract.
