Abstract

This is a procedure for stabilizing or filling an aneurysm in the vasculature. The procedure involves the introduction into the aneurysm of a solid vaso-occlusive device such as a coil or braid and a polymeric composition which may be reformed or solidified in situ. The solid vaso-occlusive device is at least partially surrounded or enveloped by that polymeric composition. The polymeric composition is reformed via light, heat, R.F. or the like to form a rigid mass with the solid vaso-occlusive device. These steps may be carried out sequentially or the steps of introducing the vaso-occlusive device and reforming the polymeric composition may be carried out simultaneously. The procedure may be accomplished using intravascular catheters to access the desired site and to deliver the noted materials.

Claims

1. A procedure for at least partially filling an aneurysm comprising the steps of:

a. introducing a vaso-occlusive device into an aneurysm,

b. introducing a formable polymeric material into said aneurysm, and

c. reforming said polymeric material in said aneurysm to bind said vaso-occlusive device.

2. The procedure of claim 1 wherein the vaso-occlusive device is electrically conductive and the reforming step is accomplished by introducing an electrical current into said vaso-occlusive device.

3. The procedure of claim 1 wherein the reforming step is accomplished by introducing radio frequency current into the vaso-occlusive device.

4. The procedure of claim 1 wherein the reforming step comprises the introduction of light into said aneurysm.

5. The procedure of claim 1 wherein the step of introducing a formable polymeric material comprises the step of introducing particulate polymeric material into said aneurysm.

6. The procedure of claim 1 wherein the step of introducing the vaso-occlusive device into the aneurysm includes the steps of introducing a distal tip of a delivery catheter into the aneurysm.

7. A procedure for at least partially filling an aneurysm comprising the steps of:

a. introducing a vaso-occlusive device which is at least partially coated with a formable polymeric material into an aneurysm, and

b. reforming said polymeric material in said aneurysm to bind said vaso-occlusive device.

8. The procedure of claim 7 wherein the vaso-occlusive device is electrically conductive and the reforming step is accomplished by introducing an electrical current into said vaso-occlusive device.

9. The procedure of claim 7 wherein the reforming step is accomplished by introducing radio frequency current into the vaso-occlusive device.

10. The procedure of claim 7 wherein the reforming step comprises the introduction of light into said aneurysm.

11. The procedure of claim 7 wherein the step of introducing the vaso-occlusive device into the aneurysm includes the steps of introducing a distal tip of a delivery catheter into the aneurysm.

12. A procedure for at least partially filling an aneurysm comprising the steps of:

a. simultaneously introducing a vaso-occlusive device and a formable polymeric material into an aneurysm, and

b. reforming said polymeric material in said aneurysm to bind said vaso-occlusive device.

13. The procedure of claim 12 wherein the vaso-occlusive device is electrically conductive and the reforming step is accomplished by introducing an electrical current into said vaso-occlusive device.

14. The procedure of claim 12 wherein the reforming step is accomplished by introducing radio frequency current into the vaso-occlusive device.

15. The procedure of claim 12 wherein the reforming step comprises the introduction of light into said aneurysm.

16. The procedure of claim 12 wherein the step of introducing a formable polymeric material comprises the step of introducing particulate polymeric material into said aneurysm.

17. The procedure of claim 12 wherein the step of introducing the vaso-occlusive device into the aneurysm includes the steps of introducing a distal tip of a delivery catheter into the aneurysm.

18. A procedure for at least partially filling an aneurysm comprising the steps of:

a. introducing a formable polymeric material into said aneurysm,

b. introducing a vaso-occlusive device into said aneurysm,

c. reforming said polymeric material in said aneurysm to bind said vaso-occlusive device.

19. The procedure of claim 18 wherein the vaso-occlusive device is electrically conductive and the reforming step is accomplished by introducing an electrical current into said vaso-occlusive device.

20. The procedure of claim 18 wherein the reforming step is accomplished by introducing radio frequency current into the vaso-occlusive device.

21. The procedure of claim 18 wherein the reforming step comprises the introduction of light into said aneurysm.

22. The procedure of claim 18 wherein the step of introducing a formable polymeric material comprises the step of introducing particulate polymeric material into said aneurysm.

23. The procedure of claim 18 wherein the step of introducing the vaso-occlusive device into the aneurysm includes the steps of introducing a distal tip of a delivery catheter into the aneurysm.
