Abstract

Sheaths of fabric material are compressed on either side of a separator by manipulating internal and external catheters to form disks which sandwich the neck of an aneurysm to obliterate the aneurysm.

Claims

1. A device for endovascular repair of vascular aneurysms or other defects in vessel walls, said device comprising at least one deployable fabric sheath which can change shape when longitudinally compressed, and means for longitudinally compressing the sheath.

2. The invention of claim 1, wherein the compressing means comprise inner and outer catheters, the inner catheter being retractable with respect to the outer catheter, and wherein the fabric sheath encircles the inner catheter.

3. The invention of claim 1, wherein the distal end of the fabric sheath is attached to a distal component of the catheter.

4. The invention of claim 1, wherein the fabric sheath or sheaths are detachable from the compressing means once suitably deployed.

5. The invention of claim 1, wherein the fabric sheath is a synthetic polymer fabric.

6. The invention of claim 5, wherein the synthetic polymer is polypropylene.

7. The invention of claim 5, wherein the synthetic polymer is polyester.

8. The invention of claim 1, wherein the fabric sheath is a natural or synthetic fabric whose shape can be altered from a cylindrical or sheath-like shape to a globular or discoid shape when compressed lengthwise.

9. A device for endovascular repair of vascular aneurysms or other defects in vessel walls, said device comprising a deployable fabric sheath having shape memory properties and constructed to form a globular or discoid shape when longitudinal traction on it is relaxed.

10. The invention of claim 9, wherein the fabric sheath has electrometric properties.

11. The invention of claim 9, wherein the fabric sheath is a synthetic polymer.

12. The invention of claim 11, wherein the synthetic polymer is a polypropylene.

13. The invention of claim 9, wherein the fabric sheath is only natural or synthetic fabric which has sufficient shape memory properties that it will change from a sheath-like or cylindrical shape to a globular or discoid shape when longitudinal traction on it is relaxed.

14. A device for endovascular repair of vascular aneurysms or other defects in vessel wall, which repairs the defect by trapping it between layers of pliable synthetic material.
