Abstract

A method of treating an aneurysm, including determining a diameter associated with a vessel having the aneurysm; selecting one of a plurality of braided implants for treating the vessel, wherein each braided implant comprises a porosity substantially consistent over up to a 1 mm diameter range, each braided implant configured to provide consistent porosity over different diameter ranges; and treating the vessel with the one of the plurality of braided implants.

First claim

What is claimed is:

1. A method of treating an aneurysm, the method comprising:
determining a vessel diameter associated with a vessel having the aneurysm, the vessel being tapered up to a 1 mm diameter range;
selecting one of a plurality of braided implants for treating the vessel, wherein each braided implant comprises a porosity consistent over the up to a 1 mm vessel diameter range, each braided implant configured to provide consistent porosity over different vessel diameter ranges; and
treating the vessel with the one of the plurality of braided implants,
wherein each braided implant of the plurality of implants comprises a porosity of 65%-70% that is consistent over the up to the 1 mm vessel diameter range.

2. The method of claim 1 , wherein the tapered vessel comprises a proximal diameter and a distal diameter that differ by up to 1 mm, wherein the determining the vessel diameter comprises comparing the proximal and distal diameters, the method further comprising:
maintaining the consistent porosity across the tapered vessel.

3. The method of claim 1 , wherein the treating the vessel further comprises:
advancing the braided implant to an aneurysm; and
reconstructing blood flow in the vessel by excluding the aneurysm and diverting blood flow from the aneurysm using the one of the plurality of braided implants.

4. The method of claim 1 , wherein the treating the vessel further comprises:
extending a first braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 2 to 3 mm.

5. The method of claim 4 , wherein the treating the vessel further comprises:
extending a second braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 2.5 to 3.5 mm.

6. The method of claim 5 , wherein a pore density of the second braided implant is 23 pores/mm2.

7. The method of claim 5 , wherein the treating the vessel further comprises:
extending a third braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 3.0 to 4.0 mm.

8. The method of claim 7 , wherein a pore density of the third braided implant is 18 pores/mm2.

9. The method of claim 7 , wherein the treating the vessel further comprises:
extending a fourth braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 3.5 to 4.5 mm.

10. The method of claim 9 , wherein a pore density of the fourth braided implant is 19 pores/mm2.

11. The method of claim 9 wherein the treating the vessel further comprises:
extending a fifth braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 4.0 to 5.0 mm.

12. The method of claim 11 , wherein a pore density of the fifth braided implant is 23 pores/mm2.

13. The method of claim 11 , wherein the treating the vessel further comprises:
extending a sixth braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 4.5 to 5.5 mm.

14. The method of claim 13 , wherein a pore density of the sixth braided implant is 21 pores/mm2.

15. The method of claim 1 , wherein the treating the vessel further comprises:
positioning the plurality of braided implants such that each of the plurality of braided implants are offset from one another by half of the range in vessel diameter of the next smallest braided implant of the plurality of braided implants.

16. A method of treating an aneurysm, the method comprising:
determining a vessel diameter associated with a vessel having the aneurysm, the vessel being tapered up to a 1 mm diameter range;
selecting one of a plurality of braided implants for treating the vessel, wherein each braided implant comprises a porosity consistent over the up to a 1 mm vessel diameter range, each braided implant configured to provide consistent porosity over different vessel diameter ranges; and
treating the vessel with the one of the plurality of braided implants,

wherein the treating the vessel further comprises:
extending a first braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 2 to 3 mm; and
extending a second braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 2.5 to 3.5 mm,
wherein a pore density of the second braided implant is 23 pores/mm2.

17. The method of claim 16 , wherein the treating the vessel further comprises:
extending a third braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 3.0 to 4.0 mm.

18. The method of claim 17 , wherein the treating the vessel further comprises:
extending a fourth braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 3.5 to 4.5 mm.

19. The method of claim 18 wherein the treating the vessel further comprises:
extending a fifth braided implant of the plurality of implants through a portion of the vessel comprising a diameter range of 4.0 to 5.0 mm.
