Abstract

A vascular remodeling device is provided that can comprise a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in the afferent vessel of a bifurcation. The distal section can comprise at least one embolization coil that can be positioned within an aneurysm to treat the aneurysm and expand from the compressed delivery state to an expanded state upon deployment. The intermediate section can allow perfusion to efferent vessels. Before, during, and/or after the device is positioned, additional embolic material can be used to treat the aneurysm.

Claims

1. An intraluminal device comprising:

a proximal section configured to anchor in an afferent vessel;

an intermediate section configured to allow perfusion to efferent vessels; and

a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism.

2. The device of claim 1, wherein the intermediate section comprises a plurality of struts.

3. The device of claim 1, wherein the embolization coil comprises a standard helical coil.

4. The device of claim 1, wherein the embolization coil comprises a 3D coil.

5. The device of claim 1, wherein the distal section comprises a plurality of embolization coils.

6. The device of claim 1, wherein the proximal section comprises a first material and the distal section comprises a second material different from the first material.

7. The device of claim 6, wherein the first material is insulated from the second material.

8. A method of treating an aneurysm near a junction of a bifurcation having an afferent vessel and efferent vessels, the aneurysm having a neck and a fundus, the method comprising:

advancing a first catheter proximate to the junction of the bifurcation, the catheter at least partially containing a device in a compressed state, the device including;

a proximal section configured to anchor in an afferent vessel;

an intermediate section configured to allow perfusion to efferent vessels; and

a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism;

deploying the device from at least partially inside the first catheter to outside the first catheter at the junction of the bifurcation, wherein, during deployment,

the distal section self-expands within the fundus of the aneurysm;

the intermediate section self-expands and allows perfusion to the efferent vessels; and

the proximal section self-expands to anchor in an expanded state to the walls of the afferent vessel.

9. The method of claim 8, wherein deploying the device comprises initially deploying the device, retrieving at least a section of the device at least partially back into the first catheter, and redeploying the device.

10. The method of claim 8, further comprising inserting additional embolic material into the aneurysm.

11. The method of claim 10, wherein inserting the additional embolic material comprises deploying the additional embolic material from the first catheter.

12. The method of claim 10, wherein inserting the additional embolic material is before deploying the device.

13. The method of claim 10, wherein inserting the additional embolic material is after deploying the device.

14. A system for treating aneurysms comprising:

at least first and second intraluminal devices, each of the first and second devices comprising;

a proximal section configured to anchor in an afferent vessel;

an intermediate section configured to allow perfusion to efferent vessels; and

a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism;

wherein the distal section of the first device comprises at least one property that is different from a corresponding property of the second device.

15. The system of claim 14, wherein the first device of the system comprises a distal section comprising a standard helical embolization coil and the second device of the system comprises a distal section comprising a 3D embolization coil.

16. The system of claim 14, wherein the first device of the system comprises a distal section comprising an embolization coil of a first length and the second device of the system comprises a distal section comprising an embolization coil of a second length, the second length being greater than the first length.

17. The system of claim 14, wherein the embolization coil of the first device comprises a first packing density and the embolization coil of the second device comprises a second packing density greater than the first packing density.

18. The system of claim 14, wherein the embolization coil of the first device comprises a first cross-sectional dimension and the embolization coil of the second device has a second cross-sectional dimension greater than the first cross-sectional dimension.

19. The system of claim 14, wherein the distal section of the first device comprises a first number of embolization coils and the distal section of the second device comprises a second number of embolization coils greater than the first number.

20. The system of claim 14, wherein the embolization coil of the distal section of the first device has a first flexibility and the embolization coil of the distal section of the second device has a second flexibility that is less than the first flexibility.
