Abstract: A device and method for remodeling or partitioning a body cavity, hollow organ or tissue tract includes graspers operable to engage two or more sections of tissue within a body cavity and to draw the engaged tissue between a first and second members of a tissue remodeling tool. The two or more pinches of tissue are held in complete or partial alignment with one another as staples or other fasteners are driven through the pinches, thus forming a four-layer tissue plication. Over time, adhesions formed between the opposed serosal layers create strong bonds that can facilitate retention of the plication over extended durations, despite the forces imparted on them by stomach movement. A cut or cut-out may be formed in the plication during or separate from the stapling step to promote edge-to-edge healing effects that will enhance tissue knitting/adhesion.

Abstract: In a method of stapling layers of tissue within a body cavity, an engaging instrument is passed between a stapler cartridge and anvil and used to engage a region of tissue. The engaging instrument is retracted to move the engaged tissue into the stapling position, and driving staples from the cartridge through at least two layers of the engaged tissue. The method and associated system may be used to form plications in body tissue, such as stomach wall tissue. Staples simultaneously driven through tissue may simultaneously capture a reinforcing elements positioned adjacent the cartridge and/or anvil prior to stapling.

Abstract: An improvement in a stapling device and method designed to capture a tissue fold between first and second members in the device to staple and cut the fold to form a stapled tissue plication with a hole therein. The improvement includes an engagement assembly in the first member movable from a retracted position in the first member to an extended position in the second member, and releasably attached to second member, an anchor assembly that includes the anchor, wherein (i) movement of the engagement assembly from the retracted to extended position, through a tissue fold captured in the device, is operable to engage the anchor assembly, and (ii) movement of the engagement assembly, with the anchor assembly engaged therewith, to its retracted position, is effective to pull at least a portion of the assembly through the hole in the stapled tissue plication.

Abstract: Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

Abstract: Methods, devices and systems for forming magnetic anastomoses between two blood vessels. A first anastomotic component is removably supported by the distal end of a delivery device for attachment to a first vessel. The delivery device also supports a second anastomotic component that has been secured to a second blood vessel. The device is operated to secure the first component to the first vessel, couple the second component to the first component, and then release the components to complete the anastomosis. A robotic anastomosis system includes several robotic instruments that may be positioned through ports in a patient, used to secure an anastomotic component to a vessel, and then used to magnetically couple the components. Delivery devices for deploying magnetic anastomotic components include an actuator that uses magnetic repulsion to move the components into engagement with the inner and outer surfaces of the vessel wall.

Abstract: Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.

Abstract: A device for dispensing a multicomponent composition comprising a mixture of different fluid components includes a first and at least a second fluid component inlet. The device also includes a mixing area located downstream from the fluid component inlets and an outlet extending from the mixing area. Each of the fluid component inlets is adapted to communicate with a source of a different fluid component. The mixing area is adapted to receive a flow of a first and at least second fluid component. Within the mixing area, the flow of the first fluid component is disrupted to allow mixing with the flow of a second fluid component to form a flow of multicomponent composition. The mixing area is further adapted to disrupt the flow of the multicomponent composition before the flow of the multicomponent composition exits through the outlet.

Abstract: Methods and devices for forming an anastomosis between hollow bodies utilize magnetic force to couple anastomotic securing components and connect the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although such attachment means may be used in practicing some aspects of the invention. The securing components have the ability to produce a magnetic field and may include materials or assemblies. A component may also be used to form a port into the lumen of a vessel, the component being attached to the vessel by mechanical and/or magnetic means. Magnetic components may include means for concentrating the magnetic flux between respective components to increase the attraction force, thereby enhancing the security of the anastomosis.
