Aneurysm occlusion system and method

A system for use in treatment of an aneurysm having a neck, the aneurysm located near a bifurcation in a vessel, the system comprising:

• at least one elongate delivery device;
• and
• a first intravascular device and a second intravascular device, at least one of the first and second intravascular devices comprising a reduced profile delivery configuration and an expanded profile deployment configuration, a proximal end and a distal end, a generally tubular segment disposed near the distal end and positionable across the neck of the aneurysm, an anchor disposed near the proximal end and positionable within the vessel, and at least one flexible link joining the generally tubular segment and the anchor, the flexible link positionable within or across a bifurcation in a vessel;
• wherein said generally tubular segment comprises a longitudinal gap.

A method of manufacture of an intravascular device, said method comprising the steps of:

• providing a tube comprising one or more shape memory materials;
• cutting the tube according to a predetermined pattern to impart a generally tubular segment having a plurality of struts and a longitudinal gap between the struts;
• an anchor and a link between the generally tubular segment and the anchor;
• shaping the intravascular device to impart a desired orientation of the generally tubular segment to the anchor;
• applying a shape memory set to the shaped cut tube.

A method of treating an aneurysm located in a blood vessel of a subject, the aneurysm having a neck and the method comprising the steps of:

• introducing into the blood vessel a first intravascular device that is radially expandable from a compressed position to an expanded position, the intravascular device comprising a tubular element having a longitudinal gap;
• an anchor;
• and a link between the tubular element and the anchor;
• bridging at least some of the neck of the aneurysm with the tubular element;
• deploying the anchor within the vessel;
• and
• delivering one or more embolic materials to the aneurysm.
