International Classification:

A61B 17/08

US Classification:

606153, 606215, 128898

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.

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61B 17/08

US Classification:

606153

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. Also, rather than form a port communicating with a lumen of a vessel or other cavity, the components may have an occlusion surface and be used to close an opening in tissue, e. g. , an atrial septal defect.

US Classification:

2221455, 222 1, 222132, 222135, 2221456, 222195, 222394, 2394275, 239428, 604 82, 604191

Abstract:

A device for dispensing a multicomponent composition composed of 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:

Described herein are endoscopic staplers used to apply one or more fasteners to body tissue. In one embodiment, a fastener-applying device, which is preferably a stapler, is 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 staplers allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver staples 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 are formed, medical devices may optionally be coupled to the plication(s) for retention within the stomach.

US Classification:

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. The anastomotic components are secured to the vessel wall by magnetic force and in addition may be secured by mechanical attachment.
