Claims
- 1. A method for endovascular blocking of an aneurysmal opening in a patient, the method comprising the steps of:inserting a catheter within a body passageway of the patient by catheterization of the body passageway, the catheter comprising a balloon portion at a distal portion thereof and a prosthesis mounted on the balloon portion, the prosthesis comprising: a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, and a leaf portion attached to the body; inserting a guidewire into the body passageway; after inserting the catheter and guidewire, translating the catheter to a target body passageway at which the aneurysm opening is located; orienting the catheter such that the leaf portion of the prosthesis is in substantial alignment with the aneurysmal opening; inflating the balloon portion of the catheter to confer a radially outward expansive force to the at least one expandable portion such that the at least one expandable portion is urged against the target body passageway; urging the leaf portion against the aneurysmal opening thereby blocking the aneurysmal opening.
- 2. The method defined in claim 1, wherein said translating step comprises moving the catheter over the guidewire.
- 3. The method defined in claim 1, wherein the leaf portion of the prosthesis comprises a pharmaceutically acceptable adhesive on a surface thereof.
- 4. The method defined in claim 1, wherein the leaf portion further comprises a pharmaceutically acceptable compound capable of expanding and entering the aneurysmal opening.
- 5. The method defined in claim 1, wherein the prosthesis comprises a coating thereof.
- 6. The method defined in claim 5, wherein the coating comprises a biologically inert material.
- 7. The method defined in claim 5, wherein the coating comprises a biologically inert material to reduce the thrombogenicity of the prosthesis.
- 8. The method defined in claim 5, wherein the coating comprises a medicinal composition.
- 9. The method defined in claim 1, wherein said urging step comprising manipulation of a positioning wire attached to the leaf portion.
- 10. The method defined in claim 1, wherein the covering material comprises a polymer.
- 11. The method defined in claim 1, wherein the covering material comprises a polyurethane/silicone polymer.
- 12. A method for endovascular blocking of an aneurysmal opening in a patient, the method comprising the steps of:inserting a catheter within a body passageway of the patient by catheterization of the body passageway, the catheter comprising a balloon portion at a distal portion thereof and a prosthesis mounted on the balloon portion, the prosthesis comprising: a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, and a leaf portion attached to the body; translating the catheter to a target body passageway at which the aneurysm opening is located; orienting the catheter such that the leaf portion of the prosthesis is in substantial alignment with the aneurysmal opening; inflating the balloon portion of the catheter to confer a radially outward expansive force to the at least one expandable portion such that the at least one expandable portion is urged against the target body passageway; urging the leaf portion against the aneurysmal opening thereby blocking the aneurysmal opening, wherein said urging step comprising urging the balloon portion of the catheter against the leaf portion of the prosthesis.
- 13. The method defined in claim 12, comprising the further step of inserting a guidewire into the body passageway prior to said translating step.
- 14. The method defined in claim 12, wherein said translating step comprises moving the catheter over the guidewire.
- 15. The method defined in claim 12, wherein the leaf portion of the prosthesis comprises a pharmaceutically acceptable adhesive on a surface thereof.
- 16. The method defined in claim 12, wherein the leaf portion further comprises a pharmaceutically acceptable compound capable of expanding and entering the aneurysmal opening.
- 17. The method defined in claim 12, wherein the prosthesis comprises a coating thereon.
- 18. The method defined in claim 17, wherein the coating comprises a biologically inert material.
- 19. The method defined in claim 17, wherein the coating comprises a biologically inert material to reduce the thrombogenicity of the prosthesis.
- 20. The method defined in claim 17, wherein the coating comprises a medicinal composition.
- 21. The method defined in claim 12, wherein said urging step comprising manipulation of a positioning wire attached to the leaf portion.
- 22. The method defined in claim 12, wherein the covering material comprises a polymer.
- 23. The method defined in claim 12, wherein the covering material comprises a polyurethane/silicone polymer.
- 24. A method for endovascular blocking off an aneurysmal opening in a patient, the method comprising the steps of:inserting a catheter within a body passageway of the patient by catheterization of the body passageway, the catheter comprising a balloon portion at a distal portion thereof and a prosthesis mounted on the balloon portion, the prosthesis comprising: a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, and a leaf portion attached to the body, wherein the leaf portion comprises a porous structure having a covering material disposed thereon; translating the catheter to a target body passageway at which the aneurysm opening is located; orienting the catheter such that the leaf portion of the prosthesis is in substantial alignment with the aneurysmal opening; inflating the balloon portion of the catheter to confer a radially outward expansive force to the at least one expandable portion such that the at least one expandable portion is urged against the target body passageway; urging the leaf portion against the aneurysmal opening thereby blocking the aneurysmal opening.
- 25. The method defined in claim 24, wherein the covering material comprises a polymer.
- 26. The method defined in claim 24, wherein the covering material comprises a polyurethane/silicone polymer.
- 27. The method defined in claim 24, comprising the further step of inserting a guidewire into the body passageway prior to said translating step.
- 28. The method defined in claim 24, wherein said translating step comprises moving the catheter over the guidewire.
- 29. The method defined in claim 24, wherein the leaf portion of the prosthesis comprises a pharmaceutically acceptable adhesive on a surface thereof.
- 30. The method defined in claim 24, wherein the leaf portion further comprises a pharmaceutically acceptable compound capable of expanding and entering the aneurysmal opening.
- 31. The method defined in claim 24, wherein the prosthesis comprises a coating thereon.
- 32. The method defined in claim 31, wherein the coating comprises a biologically inert material.
- 33. The method defined in claim 31, wherein the coating comprises a biologically inert material to reduce the thrombogenicity of the prostheses.
- 34. The method defined in claim 31, wherein the coating comprises a medicinal composition.
- 35. The method defined in claim 24, wherein said urging step comprising manipulation of a positioning wire attached to the leaf portion.
