1. A catheter system for intraluminal delivery of an aneurysm treatment system, the catheter system comprising:
a catheter having a proximal end and a distal end, the catheter having a delivery portion near the distal end, a balloon inflation fluid pathway extending from a proximal portion of the catheter to an expandable balloon on the delivery portion of the catheter, and a fixation medium delivery pathway extending from the proximal portion to the delivery portion; and a double-walled filling structure disposed on the balloon and adapted for intraluminal placement at an intersection of a main vessel and at least one side branch vessel, the filling structure comprising an inner wall, an outer wall outside of an exterior of the inner wall, and a fillable void between the inner and outer wall, wherein, when deployed by filling the void with a fixation media delivered through the fixation medium delivery pathway, the inner wall surrounds and defines a primary fluid conduit having an upper and lower opening to facilitate blood flow across the intersection and further surrounds and defines at least one lateral fluid conduit in fluid communication between the upper and lower openings to facilitate blood flow from the primary fluid conduit through the at least one lateral fluid conduit into the at least one side branch vessel, and the outer wall conforms to an inside wall of the main vessel along the primary fluid conduit and to an inside wall of the at least one lateral fluid conduit along an arm of the filling structure extending into the at least one sidebranch vessel so as to substantially fill a space between an outside surface of the outer wall and the wall of each of the main vessel and the at least one side branch vessel at the intersection of the main and the at least one side branch vessel. |
