Abstract

Non-expandable space-occupying devices for treating voids within the body are disclosed. The devices can have multiple non-expandable space-occupying elements connected to a flexible leaden. Methods of making and using the devices are also disclosed.

Claims

1. A device for filling a void within a body comprising:

a first space-occupying element comprising a first male interference-fit piece, wherein the first male interference-fit piece is solid; and

a second space-occupying element comprising a first female interference-fit piece coupled to the first male interference-fit piece, wherein the second space-occupying element comprises a longitudinal axis, and wherein the first female interference-fit piece comprises a lateral open wall relative to the longitudinal axis.

2. The device of claim 1, wherein the device comprises a collagen coating.

3. The device of claim 1, wherein the device comprises a time-release coating.

4. The device of claim 1, wherein the device comprises a time-release coating.

5. The device of claim 1, wherein the first space-occupying element comprises a polymer.

6. The device of claim 1, wherein the second space-occupying element comprises a polymer.

7. The device of claim 1, wherein the male interference-fit piece comprises a poppet.

8. The device of claim 1, wherein the female interference-fit piece comprises a socket.

9. The device of claim 1, wherein the first space-occupying element comprises a second female interference-fit piece.

10. The device of claim 1, wherein the first space-occupying element comprises a second male interference-fit piece.

11. The device of claim 10, wherein the first male interference-fit piece is on the opposite side of the first space-occupying element from the second male interference-fit piece.

12. The device of claim 1, wherein the second space-occupying element comprises a second male interference-fit piece.

13. The device of claim 1, wherein the second space-occupying element comprises a second female interference-fit piece.

14. The device of claim 13, wherein the first female interference-fit piece is on the opposite side of the first space-occupying element from the second female interference-fit piece.

15. The device of claim 1, wherein the coupling of the first female interference-fit piece to the first male interference-fit piece is configured to allow the first space-occupying element rotate with respect to the second space-occupying element in a first dimension.

16. The device of claim 15, wherein the coupling of the first female interference-fit piece to the first male interference-fit piece is configured to allow the first space-occupying element rotate with respect to the second space-occupying element in a second dimension.

17. The device of claim 1, wherein the device is configured to be absorbed by the body.

18. The device of claim 1, further comprising a flexible leader extending, through the first space-occupying element and the second space-occupying element.

19. A device for filling a void within the body comprising:

a first space-occupying element comprising, a spherical interference-fit piece, wherein the spherical interference-fit piece is solid; and

a second space-occupying element comprising a female interference-fit piece coupled to the spherical interference-fit piece, wherein the second space-occupying element comprises a longitudinal axis, and wherein the female interference-fit piece comprises a lateral open wall relative to the longitudinal axis.

20. A device for filling a void within the body comprising:

a first space-occupying element comprising a spherical interference-fit piece, wherein the spherical interference-fit piece is solid; and

a second space-occupying element comprising a first female interference-fit piece coupled to the first male interference-fit piece, wherein the second space-occupying element comprises a longitudinal axis, and wherein the first female interference-fit piece comprises a lateral open wall relative to the longitudinal axis.
