Expandable vascular occlusion device

1. An occlusion device comprising:

a generally tubular element which is capable of being transformed between a collapsed position and an expanded position, said tubular element being formed by a wall having a plurality of apertures extending through the wall;

an inner embolic device located at least partially within the generally tubular element so that at least a portion of the inner embolic device is covered by the expandable generally tubular element; and

said expandable generally tubular element is attached to the inner embolic device, wherein the tubular element has a preselected shape in the expanded position;

wherein the generally tubular element expands at body temperature.

2. The occlusion device of claim 1 wherein the generally tubular element covers substantially the entire inner embolic device.

3. The occlusion device of claim 1 wherein the generally tubular element further includes a proximal end and a distal end, and at least the proximal end and the distal end are attached to the inner embolic member.

4. The occlusion device of claim 1 wherein the generally tubular element comprises a material having super-elastic properties.

5. The occlusion device of claim 1 wherein the generally tubular element comprise a material having shape memory.

6. The occlusion device of claim 1 wherein the generally tubular element comprises a metal.

7. The occlusion device of claim 6 wherein the metal is a nickel-titanium alloy.

8. The occlusion device of claim 1 wherein the inner embolic device is an embolic coil.

9. The occlusion device of claim 1 wherein the embolic coil is configured to have complex curves.

10. The occlusion device of claim 1 wherein the apertures are formed by perforating the wall.

11. The occlusion device of claim 1 wherein the tubular element wall is unitary and at least a portion of the generally tubular element expands in response to pressure applied by the inner embolic device.

12. An intraluminal device, comprising:

an embolic coil; and

an expandable generally tubular thin film mesh covering at least a portion of the embolic coil and being attached to the embolic coil, said generally tubular thin film mesh comprising a perforated unitary wall, wherein the tubular thin film mesh has a preselected shape in an expanded position;

wherein the generally tubular thin film mesh expands at body temperature.

13. The intraluminal device of claim 12 wherein the expandable generally tubular thin film mesh covers substantially the entire embolic coil.

14. The intraluminal device of claim 12 wherein the expandable generally tubular thin film mesh includes a proximal end and a distal end wherein at least the proximal end and the distal end are attached to the embolic coil.

15. The intraluminal device of claim 12 wherein the expandable generally tubular thin film mesh has a thickness greater than about 0.1 microns but less than about 5 microns.

16. A method of occluding a vessel within a patient, comprising:

using an occlusion device having a generally tubular element which is capable of being transformed between a collapsed position and an expanded position, the tubular element has a preselected shape in the expanded position, said tubular element being formed by a wall having a plurality of apertures extending through the wall, and an inner embolic device at least partially within the generally tubular element so that at least a portion of the inner embolic device is covered by the expandable generally tubular element, said expandable generally tubular element being attached to the embolic device;

placing the vascular occlusion device within a vessel of a patient and directing same to a diseased-location of the vessel; and

expanding the generally tubular element at body temperature in the diseased location.

17. The method according to claim 16 wherein the providing further includes providing a generally tubular element that expands upon a rise in temperature; and

the expanding comprises raising the temperature of the generally tubular element.
