Abstract

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

Claims (55)

1. A device for treating a thrombus in a vessel, the device comprising:

a plurality of wires woven to form a textile fabric, the textile fabric being completely hollow and comprising:

ten self-expanding bulbs,

nine necks longitudinally between the ten self-expanding bulbs, and

a distal neck distal to the distal-most of the ten self-expanding bulbs,

the plurality of wires comprising:

a plurality of radiopaque wires, and

a plurality of shape-memory wires.

2. The device of claim 1 , wherein the ten self-expanding bulbs comprise:

a first bulb;

a second bulb distal to the first bulb, the first bulb and the second bulb having a first diameter;

a third bulb distal to the second bulb;

a fourth bulb distal to the third bulb, the third bulb and the fourth bulb having a second diameter smaller than the first diameter;

a fifth bulb distal to the fourth bulb;

a sixth bulb distal to the fifth bulb;

a seventh bulb distal to the sixth bulb, the fifth bulb, the sixth bulb, and the seventh bulb having a third diameter smaller than the second diameter;

an eighth bulb distal to the seventh bulb;

a ninth bulb distal to the eighth bulb; and

a tenth bulb distal to the ninth bulb, the eighth bulb, the ninth bulb, and the tenth bulb having a fourth diameter smaller than the third diameter.

3. The device of claim 1 , wherein the ten self-expanding bulbs comprise:

a first bulb, the first bulb having a generally oblong shape;

a second bulb distal to the first bulb, the second bulb having a generally spherical shape;

a third bulb distal to the second bulb, the third bulb having a generally oblong shape;

a fourth bulb distal to the third bulb, the fourth bulb having a generally spherical shape;

a fifth bulb distal to the fourth bulb, the fifth bulb having a generally oblong shape;

a sixth bulb distal to the fifth bulb, the sixth bulb having a generally spherical shape;

a seventh bulb distal to the sixth bulb, the seventh bulb having a generally spherical shape;

an eighth bulb distal to the seventh bulb, the eighth bulb having a generally oblong shape;

a ninth bulb distal to the eighth bulb, the ninth bulb having a generally spherical shape; and

a tenth bulb distal to the ninth bulb, the tenth bulb having a generally spherical shape.

4. The device of claim 3 , wherein:

the first bulb and the second bulb have a first diameter;

the third bulb and the fourth bulb have a second diameter smaller than the first diameter;

the fifth bulb, the sixth bulb, and the seventh bulb have a third diameter smaller than the second diameter; and

the eighth bulb, the ninth bulb, and the tenth bulb have a fourth diameter smaller than the third diameter.

5. A device for treating a thrombus in a vessel, the device comprising:

a plurality of wires woven to form a textile fabric comprising a free distal end, the textile fabric comprising a plurality of bulbs and a plurality of necks in a radially expanded state, the plurality of bulbs spaced by the plurality of necks, the plurality of wires comprising shape-memory wires and radiopaque wires.

6. The device of claim 5 , wherein the radiopaque wires comprise platinum tungsten.

7. The device of claim 5 , wherein the shape memory wires comprise nickel titanium.

8. The device of claim 5 , wherein the plurality of bulbs comprises ten bulbs.

9. The device of claim 5 , wherein at least two of the plurality of bulbs have different outer diameters in the radially expanded state.

10. The device of claim 5 , wherein a diameter of the device in a collapsed state is no more than about 0.0125 inches.

11. The device of claim 5 , wherein at least two of the plurality of bulbs have different shapes in the radially expanded state.

12. The device of claim 5 , wherein at least one of the plurality of bulbs has a spherical shape in the radially expanded state.

13. The device of claim 5 , wherein at least one of the plurality of bulbs has an oblong shape in the radially expanded state.

14. A device for treating a vessel, the device comprising:

a plurality of wires woven to form a completely hollow textile fabric comprising:

a radially collapsed state having a diameter between about 0.25 mm and about 0.5 mm, and

a radially expanded state having a diameter between about 1 mm and about 30 mm, the textile fabric comprising a plurality of bulbs and a plurality of necks in the radially expanded state.

15. The device of claim 14 , wherein the plurality of bulbs comprises ten bulbs.

16. The device of claim 14 , wherein at least two of the plurality of bulbs have different outer diameters in the radially expanded state.

17. The device of claim 14 , wherein at least two of the plurality of bulbs have different shapes in the radially expanded state.

18. The device of claim 14 , wherein at least one of the plurality of bulbs has a spherical shape in the radially expanded state.

19. The device of claim 14 , wherein at least one of the plurality of bulbs has an oblong shape in the radially expanded state.

20. The device of claim 14 , wherein the plurality of bulbs are spaced by necks.
