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

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.

Magnetic anastomosis devices and methods of delivery

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 are 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.

Systems, devices, and methods for forming anastomoses

The present invention features new methods, apparatuses and devices for fixing adjacent bone segments, segments of a bony structure and adjacent vertebrate of a spine. The methods, apparatuses and devices utilize a new apparatus for forming a channel in a surface of the bone or bony structure segments or adjacent vertebra or a channel submerged within the bone or bony structure segments or adjacent vertebra. In more particular embodiments such apparatuses and methods including forming an arcuate channel and which channel can receive therein a curved rod or implant member, which also preferably is arcuate, and avoids the associated problems with prior cage or straight rod and screw systems. Also featured are systems, apparatuses and methods for repairing, replacing or augmenting the nucleus and/or annulus of a disc.

Systems, devices and apparatuses for bony fixation and disk repair and replacement methods related thereto

The present invention features new methods, apparatuses and devices for fixing adjacent bone segments, segments of a bony structure and adjacent vertebrate of a spine. The methods, apparatuses and devices utilize an apparatus for forming a channel in a surface of the bone or bony structure segments or adjacent vertebra or a channel submerged within the bone or bony structure segments or adjacent vertebra. In more particular embodiments such apparatuses and methods including forming an arcuate channel and which channel can receive therein a curved rod or implant member. Also featured are systems, apparatuses and methods for removably suspending a spacer in the intervertebral space while forming such a channel as well as systems, apparatuses and methods for use of dynamized implant members.

Disclosed is an apparatus for forming an arcuate channel in one or more segments of a bone, bony structure or adjacent vertebrae of a spine. The apparatus includes, inter alia, a base member which is positioned proximate to the surgical site, a support arm extending proximally from the base member, an arcuate guide member and a drill assembly. The arcuate guide member is slidably mounted to the support arm. The drill assembly is operatively coupled to the support arm and includes a drill bit attached to the distal end of a flexible drive cable. The flexible drive cable extends axially along the support arm and is axially and rotationally movable with respect thereto. The drill bit is operatively coupled to an end of the arcuate guide member such that when the drill assembly is moved distally, the arcuate guide member slides with respect to the support arm and forces the drill bit to traverse an arcuate path.
