Abstract

Methods for securing strand ends of devices configured for insertion into an anatomical structure, and the resulting devices.

Claims

1. A device configured for insertion into an anatomical structure, the device comprising:

a plurality of strands, each strand including a strand portion on both sides of a strand bend, each of the strand portions having an end, the plurality of strands being woven to form a body having;

a first body end;

a second body end; and

a body length between the first body end and the second body end;

pairs of strand portion ends being secured together, each pair of secured strand portion ends forming a joint assembly that is spaced apart from each end of the body and wherein each joint assembly is positioned beneath a strand of the device that crosses over the secured strand portion ends at a strand crossing;

wherein a length of each joint assembly along a longitudinal axis of the joint assembly is between 0.1 percent and 15 percent of the body length.

2. The device of claim 1, wherein the length of each joint assembly is less than 2 percent of the body length.

3. The device of claim 1, wherein a pair of strand portion ends is secured side-by-side.

4. The device of claim 1, wherein a pair of strand portion ends is secured end-to-end.

5. The device of claim 1, wherein each of the joint assemblies is substantially centered beneath the strand that passes thereover.

6. The device of claim 1, wherein the device IS configured as a self-expanding stent.

7. The device of claim 1, wherein each said joint assembly is nearer to one of the first body end and the second body end than to the other of the first body end and the second body end.

8. The device of claim 1, wherein each joint assembly is spaced apart from each of the first body end and the second body end by least two strand crossings.

9. The device of claim 1, wherein a pair of secured strand portion ends is secured by soldering.

10. The device of claim 1, wherein a pair of secured strand portion ends is secured by welding.
