Abstract

An occluding device for occluding fluid flow through a lumen of a body vessel. The device comprises a coil and fibers attached to the coil. The coil has about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed. The fibers extend from the coil at a length.

Claims

1. A method of occluding fluid flow through a lumen of a body vessel, the method comprising:

deploying a first portion of an occluding device at a desired point of occlusion in the body vessel, the occluding device comprising a primary coil having a primary body with a plurality of primary loops and fibers attached to the primary coil and extending therefrom, the occluding device forming a secondary coil defining a plurality of secondary loops, wherein the fibers are wedged between the primary loops and held between the primary loops by an initial tension in the primary coil, the fibers not being looped about turns of the primary loops, wherein the coil has about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed, wherein the initial tension represents the amount of force necessary to cause a 4 centimeter length of the coil to begin to elongate;

ascertaining a position of the first portion relative to the desired point of occlusion in the body; and

deploying a remaining portion of the occluding device to pack the secondary loops together to occlude the lumen, if the first portion is at the desired point of occlusion in the body.

2. A method of occluding fluid flow through a lumen of a body vessel, the method comprising:

deploying a first portion of an occluding device at a desired point of occlusion in the body vessel, the occluding device comprising;

a primary coil including a series of first loops and having an initial tension of between about 10 and 30 grams of weight to facilitate the primary coil to be folded in a packed state across the lumen of the body vessel when being deployed, the primary coil being formed into a secondary coil; and

fibers attached to the primary coil and extending radially therefrom, the fibers being held between the first loops of the primary coil by the initial tension of the primary coil, the fibers not being looped about turns of the first loops;

wherein the initial tension represents the amount of force necessary to cause a 4 centimeter length of the primary coil to begin to elongate,

ascertaining a position of the first portion relative to the desired point of occlusion in the body; and

deploying a remaining portion of the occluding device to pack the loops together to occlude the lumen, if the first portion is at the desired point of occlusion in the body.

3. The method of claim 2 wherein deploying the remaining portion of the occluding device includes folding the remaining portion of the occluding device with the first portion to pack the loops together to occlude the lumen.

4. The method of claim 2 further comprising:

adjusting the position of the first portion relative to the desired point of occlusion in the body vessel, if the first portion is off the desired point of occlusion.

5. The method of claim 2 further comprising:

introducing a guide catheter in the body vessel;

passing a microcatheter through the guide catheter to position the microcatheter at the desired point of occlusion in the body vessel, the microcatheter having a hub;

loading the occluding device at the hub of the microcatheter; and

advancing the occluding device to a distal end of the microcatheter for deployment at the desired point of occlusion in the body vessel.

6. The method of claim 5 wherein the guide catheter is between about 4-French and 8-French.

7. The method of claim 5 wherein the microcatheter has an inside diameter of between about 0.014 and 0.038 inch.

8. The method of claim 5, wherein the occluding device is advanced with saline solution and a syringe in fluid communication with a proximal end of the microcatheter.

9. The method of claim 2 wherein deploying the remaining portion of the occluding device includes occluding a cross-sectional area of the lumen at the desired point of occlusion.

10. A method of occluding fluid flow through a lumen of a body vessel, the method comprising:

deploying a first portion of an occluding device at a desired point of occlusion in the body vessel, the occluding device comprising a coil and fibers attached to the coil and extending therefrom, the coil having about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed, wherein the initial tension represents the amount of force necessary to cause a 4 centimeter length of the coil to begin to elongate, the occluding device forming a plurality of loops;

ascertaining a position of the first portion relative to the desired point of occlusion in the body; and

deploying a remaining portion of the occluding device to pack the loops together to occlude the lumen, if the first portion is at the desired point of occlusion in the body.

11. The method of claim 10 wherein deploying the remaining portion of the occluding device includes folding the remaining portion of the occluding device with the first portion to pack the secondary loops together to occlude the lumen.

12. The method of claim 10 further comprising:

adjusting the position of the first portion relative to the desired point of occlusion in the body vessel, if the first portion is off the desired point of occlusion.

13. The method of claim 10 further comprising:

introducing a guide catheter in the body vessel;

passing a microcatheter through the guide catheter to position the microcatheter at the desired point of occlusion in the body vessel, the microcatheter having a hub;

loading the occluding device at the hub of the microcatheter; and

advancing the occluding device to a distal end of the microcatheter for deployment at the desired point of occlusion in the body vessel.

14. The method of claim 13 wherein the guide catheter is between about 4-French and 8-French.

15. The method of claim 13 wherein the microcatheter has an inside diameter of between about 0.014 and 0.038 inch.

16. The method of claim 13 wherein the occluding device is advanced with a pusher wire.

17. The method of claim 13, wherein the occluding device is advanced with saline solution and a syringe in fluid communication with a proximal end of the microcatheter.

18. The method of claim 10 wherein deploying the remaining portion of the occluding device includes occluding a cross-sectional area of the lumen at the desired point of occlusion.

19. The method of claim 10 wherein the occluding device is advanced with a pusher wire.
