摘要： Systems and methods for creating an arteriovenous (AV) fistula comprise an elongate member, a distal member connected to the elongate member and movable relative to the elongate member, and a heating member disposed on at least one of the movable distal member and the elongate member. The distal member comprises structure for capturing tissue to be cut to create the fistula, and the heating member is adapted to cut through the tissue to create the fistula. The elongate member comprises an elongate outer tube. A shaft connects the distal member to the elongate member, and is extendable and retractable to extend and retract the distal member relative to the elongate member.

摘要： 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.

摘要： A stent graft system for intraluminal deployment in an aorta and a branch vessel includes an aorta stent graft with a fenestration aligned with a branch vessel and a branch vessel prosthesis with a flaring portion at a proximal end and a tubular portion. When deployed, the flaring portion of the branch vessel prosthesis is retained within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel. The system includes at least one positional indicator, including a positional indicator associated with the branch vessel prosthesis for indicating the position of a point along the branch vessel prosthesis predetermined for optimal alignment with the fenestration during deployment.

摘要： An anastomotic connector includes a tubular shell and a porous biocompatible liner configured to connect two or more natural and/or artificial lumens, such as blood vessels and/or grafts. The tubular shell may be bioabsorbable, ultimately dissolving in the body, while the biocompatible liner can remain in the body and connected to the lumens.

摘要： A method of creating an AV fistula between adjacent first and second blood vessels, includes steps of cutting a hole through the adjacent walls of the first and second blood vessels and inserting a welding catheter into the first vessel, and through the hole into the second vessel, so that a distal end of the welding catheter is disposed within the second vessel. A portion of wall defining the welding catheter is then expanded radially outwardly, and the expanded wall portion is pulled proximally to engage the wall of the second blood vessel and to pull it toward the wall of the first blood vessel. Then, a portion of wall proximal to the first expanded wall portion and disposed in the first blood vessel is expanded radially outwardly, thereby capturing the walls of each of the second and first blood vessels between the two expanded wall portions. Cutting elements on the expanded wall portions are then energized to create a tissue welded elongate aperture between the first and second blood vessels.

摘要： A method of retrieving a pair of previously implanted magnets from a patient's body includes maneuvering a guide catheter, which includes a guide magnet affixed to its distal end, toward the implantation site of the implanted magnets. The guide magnet is magnetically coupled to one of the implanted magnets in an orientation in which a through hole of the guide magnet is in register with through holes of the first and second implant magnets. An elongate capture member is slid through the lumen of the guide catheter until one of a proximal segment and a distal segment extends through the through holes of the guide magnet and the implanted magnets. An abutment segment of the elongate capture member, which separates the proximal segment and the distal segment is maneuvered into contact with the magnets. Then, the abutment segment, the guide magnet and the implanted magnets are moved as a group away from the implantation site.
