Abstract

Disclosed herein are vaso-occlusive devices for forming occluding the vasculature of a patient. More particularly, disclosed herein are vaso-occlusive devices having a textured outer surface for promoting tissue in-growth.

First claim

What is claimed is:

1. An occlusive device having an outer surface, the outer surface comprising a continuous, non-randomly textured material defining raised and depressed regions, wherein the raised regions are arranged in a repeating manner about at least a portion of such outer surface and are separated from neighboring raised regions by uniform axial distance and a uniform radial distance, wherein the raised regions are gradually concave and taper to a rounded point projecting away from the surface.

2. The occlusive device of claim 1 , further comprising a core wire.

3. The occlusive device of claim 1 , wherein the device comprises a metal selected from the group consisting of gold, nickel, titanium, tantalum, platinum and alloys thereof.

4. The occlusive device of claim 1 , wherein the device is a helical coil.

5. The occlusive device of claim 1 , wherein the device has a secondary shape that self-forms upon deployment.

6. The occlusive device of claim 5 , wherein the secondary shape comprises a plurality of connected looped segments and wherein each segment lies in a different plane from an adjacent segment.

7. The occlusive device of claim 5 , where the secondary shape is selected from the group consisting of cloverleaf shaped, helically-shaped, figure-8 shaped, flowershaped, vortex-shaped, ovoid, randomly shaped, and substantially spherical.

8. The occlusive device of claim 1 , further comprising a detachment junction.

9. The occlusive device of claim 8 , wherein the detachable junction is detachable by mechanical, hydraulic, electrical, electromagnetic, thermal, or sonic means.

10. A method of at least partially occluding an aneurysm, comprising introducing an occlusive device according to claim 1 into the aneurysm.
