Methods and devices for forming magnetic anastomoses between hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created with or without a mechanical connection between the components. The anastomotic components may have various constructions and may be secured to a vessel in various manners, for example, magnetically, mechanically or adhesively. Also provided are alternative delivery devices, as well as devices for checking the position of a component on a loaded delivery device, and for checking the seal between a vessel and an anastomotic component secured thereto.
摘要:
An anastomosis device has first and second components which each having first and second parts. The first and second components are magnetically attracted to one another. The device forms a throughhole when in use. The first parts of the first and second components are positioned radially outward from the second parts relative to the longitudinal axis with the first parts of the first and second components contacting one another and being magnetically attracted to one another. The second parts of the first and second components also being magnetically attracted to one another and are separated by the vessel walls.

Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.

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.

摘要:
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.
