  • Patent number: 11638638
    Abstract: A system for treating an aneurysm includes a first double-walled filling structure having an outer wall and an inner wall. 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 generally tubular lumen to permit blood flow therethrough. The inner wall comprises a blood contacting layer and a reinforcing layer. The reinforcing layer prevents circumferential creep or elastic expansion of the lumen.

  • Publication number: 20210369438
    Abstract: A system for treating an aneurysm comprises at least a first double-walled filling structure having an outer wall and an inner wall and the filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to the inside surface of the aneurysm and the inner surface forms a generally tubular lumen to provide blood flow. The first filling structure comprises a sealing feature which forms a fluid seal between the filling structure and the aneurysm or an adjacent endograft when the filling structure is filled with the hardenable fluid filling medium, thereby minimizing or preventing blood flow downstream of the seal.

  • Patent number: 8801768
    Abstract: Aneurysms are treated by filling at least one double-walled filling structure with a filling medium within the aneurysm, such as filling structures having a membrane that allows water molecules to permeate across the membrane in response to a water potential differential across the membrane. The transport of fluid across the membrane allows the bag to expand or shrink to accommodate changes in the size or shape of the aneurysm, thereby maintaining a seal between the filling structure against the vessel wall and maintaining apposition of the filling structure against the inside surface of the aneurysm. Transport of water molecules into or out of the filling structure is controlled by adjusting for the osmolarity of the filling fluid medium. The filling structures may be delivered over balloon deployment mechanisms in order to shape occlude the aneurysm and open a tubular lumen for flow of blood through the filling structure.

  • Publication number: 20090319029
    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.
