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.

Magnetic anastomosis devices with varying magnetic force at a distance

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.

Methods and apparatus for magnet-induced compression anastomosis between adjacent organs

The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon. A coupled set of polygons define a circumscribed tissue that can be perforated, or the tissue can be allowed to naturally necrose and perforate. The device can be used to create anastomoses in a variety of tissues, such as tissues found in the gastrointestinal, renal/urinary, and reproductive tracts. New procedures for using anastomoses, e.g., surgical bypass are also disclosed.

Self-assembling magnetic anastomosis device having an exoskeleton

The invention concerns delivering paired magnetic anastomosis devices to either side of tissues to be joined. The magnetic anastomosis devices are coupled to a guide element that facilitates delivery and manipulation of the devices when using minimally-invasive techniques such as endoscopy and laparoscopy. Elongated manipulators and guide tubes ae also disclosed that improve a user's dexterity with the devices during placement.

The invention relates to deployable magnetic compression devices and systems and methods for the deployment of such magnetic compression devices. The magnetic compression devices are particularly useful for creating anastomoses, e.g., in the gastrointestinal tract. The devices are especially useful for minimally-invasive delivery, e.g., using endoscopic techniques. The systems, devices, and methods can be used to treat a variety of gastrointestinal and metabolic diseases, such as diabetes, obesity, and cancer.
