DOCKING APPARATUS AND METHODS OF USE
First Claim
1. A system for treating an aneurysm in a blood vessel, said system comprising:
- a docking scaffold radially expandable from a contracted configuration to an expanded configuration and having an upstream end, a downstream end and a central passageway therebetween, wherein in the expanded configuration the upstream end engages a portion of the blood vessel upstream of the aneurysm;
a first leg scaffold radially expandable from a contracted configuration to an expanded configuration, wherein a portion of the first leg scaffold is slidably received in the central passageway such that an outside surface of the first leg scaffold in the expanded configuration engages an inside surface of the docking scaffold;
a second leg scaffold radially expandable from a contracted configuration to an expanded configuration, wherein a portion of the second leg scaffold is slidably received in the central passageway such that an outside surface of the second leg scaffold in the expanded configuration engages an inside surface of the docking scaffold, anda first double-walled filling structure, the filling structure having an outer wall and an inner wall, wherein the filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a first substantially tubular lumen to provide a path for blood flow therethrough,wherein the first double-walled filling structure is coupled with at least one of the leg scaffolds in the expanded configuration.

Abstract
A system for treating an aneurysm in a blood vessel comprises a docking scaffold having with upstream and downstream ends, and a central passageway therebetween. The upstream end engages the blood vessel upstream of the aneurysm. A portion of a first and second scaffolds are slidably received in the central passageway such that an outside surface of the first and second scaffolds engage an inside surface of the docking scaffold. A double-walled filling structure has outer and inner walls and the filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow therethrough. The double-walled filling structure is coupled with at least one of the first and second leg scaffolds in expanded configuration.

44. A method for treating an aneurysm in a blood vessel, said method comprising:
-
advancing a docking scaffold through the blood vessel to a position upstream of the aneurysm; radially expanding the docking scaffold from a contracted configuration to an expanded configuration, wherein in the expanded configuration the docking scaffold engages a portion of the blood vessel upstream of the aneurysm; advancing a first leg scaffold through the blood vessel toward the docking scaffold so that the first leg scaffold is slidably received by the docking scaffold; radially expanding the first leg scaffold from a contracted configuration to an expanded configuration, wherein in the expanded configuration the first leg scaffold engages at least a portion of an inner surface of the docking scaffold; advancing a second leg scaffold through the blood vessel toward the docking scaffold so that the second leg scaffold is slidably received by the docking scaffold; radially expanding the second leg scaffold from a contracted configuration to an expanded configuration, wherein in the expanded configuration the second leg scaffold engages at least a portion of the inner surface of the docking scaffold; advancing a first double-walled filling structure through the blood vessel toward the aneurysm; and filling the first double-walled filling structure with a fluid filling medium so that an outer wall of the first filling structure conforms to an inside surface of the aneurysm and an inner wall of the first filling structure forms a first substantially tubular lumen to provide a first blood flow path across the aneurysm, wherein the first filling structure is coupled with at least one of the leg scaffolds in the expanded configuration. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
