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 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 of 65%-70% that is consistent over the up to a 1 mm diameter range, each braided implant configured to provide consistent porosity over different 1 mm diameter ranges; and
treating the vessel with the one of the plurality of braided implants.

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 end diameters, the method further comprising:
maintaining the consistent porosity across the tapered braided implant.

3. The method of claim 1 , wherein the treating the vessel 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 selected one of the plurality of braided implants.

4. The method of claim 1 , the vessel is tapered and the diameter of the vessel ranges between 3-4 mm.

5. The method of claim 1 , the vessel is tapered and the diameter of the vessel ranges between 3.5-4.5 mm.

6. The method of claim 1 , the vessel is tapered and the diameter of the vessel ranges between 4-5 mm.

7. The method of claim 1 , the vessel is tapered and the diameter of the vessel ranges between 4.5-5.5 mm.

8. The method of claim 1 , the vessel is tapered and the plurality of braided implants is configured to treat vessel diameters ranging between 1.5-6 mm.

9. The method of claim 1 , the step of determining the diameter is implemented by X-ray, fluoroscopy, or MRI.

10. The method of claim 1 , wherein a predetermined length between proximal and distal ends of at least one of the braided implants is at least 3 cm.

11. The method of claim 1 , wherein a predetermined length between proximal and distal ends of at least one of the braided implants is at least 1 cm.

12. The method of claim 1 , further comprising:
providing, for each braided implant, an indicated diameter that coincides with a peak of a porosity curve of the respective braided implant.

13. The method of claim 12 , further comprising:
corresponding a porosity plateau to the 1 mm diameter range disposed about the peak of the porosity curve.

14. The method of claim 1 , wherein a pore density of each braided implant is 18 to 23 pores/mm 2 .

15. The method of claim 1 , wherein at least one of the braided implants is a cylindrical porous structure.

16. The method of claim 1 , further comprising:
forming at least one of the braided implants from a plurality of single strands composed of at least a first material and one or more radiopaque multi-strands.

17. The method of claim 1 , further comprising:
forming at least one of the braided implants of monofilaments each laid together with monofilaments, respectively.

18. The method of claim 1 , wherein the 1 mm diameter range of each of the plurality of braided implants overlaps with the 1 mm diameter ranges of at least one other braided implant of the plurality of braided implants.

19. The method of claim 1 , wherein the 1 mm diameter range of each of the plurality of braided implants overlaps with the 1 mm diameter ranges of at least one other braided implant of the plurality of braided implants by 0.5 mm.

20. The method of claim 16 , wherein the strands of the multi-strands are parallel to each other.
