A plurality of structural layers having different properties are nested together to form the medical balloon. Certain embodiments include at least one layer comprising a fiber-reinforced polymer. The layers of the balloons can slide relative to one another in use. A structural layer may comprise metal reinforcing fibers suspended in a polymer matrix.

Medical balloon having a plurality of structural layers

A vascular occlusion device that includes an inner embolic member at least partially covered by an expandable generally tubular mesh. The expandable tubular mesh typically comprises a unitary wall with apertures through the wall to assist in the expansion of the generally tubular mesh.

Expandable vascular occlusion device

A method of occluding a defect in the wall of a body vessel is provided. An outlet portion of a microcatheter is delivered to the defect, then at least a body portion of a thin film occlusion device is radially expanded from a collapsed orientation to a deployed orientation for engaging the microcatheter and covering at least a portion of the defect. Thereafter, an embolic media is released into the defect from the microcatheter for facilitating thrombosis. The body portion of the occlusion device is substantially porous in the collapsed orientation, but substantially non-porous in the deployed orientation for preventing prolapse of the embolic media into the body vessel.

Remodeling device for aneurysms

Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Open slots in selected portions of the device telescope as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. Closed slits in other portions of the device open as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while remaining open for fluid flow or endothelialization. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of mesh layers having unaligned pore systems which further reduce porosity in desired portions of the deployed configuration.
