FIG 3. In vitro experiment. The liner has been deployed in a model wide-necked side-wall aneurysm and filled with three GDCs. The liner has retained the coils in the neck. It remains attached to its delivery catheter.

FIG 4. The liner, containing three coils, was retrieved from the in vitro aneurysm model. The first few millimeters of the first coil have penetrated the liner but the remaining coils are contained. The distal marker ring of the liner is visible as a dark dot in the upper third of the specimen.
