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 leader. Methods of making and using the devices are also disclosed.

Claims

1. A method for filling an abnormal void within the body comprising:

inserting a filling device into a closed sac volume, wherein the filling device comprises a rotatable joint comprising a flexible leader and a space-occupying element comprising a substantially spherical body;

pushing the filling device in the closed sac volume;

substantially filling the closed sac volume with the filling device; and

inserting a vascular prosthesis adjacent to the abnormal void, and wherein inserting the filling device further comprises deploying the filling device between a vascular wall adjacent to the closed sac volume and the vascular prosthesis.

2. The method of claim 1, wherein the substantially spherical body comprises a poppet.

3. The method of claim 1, wherein the filling device comprises a female interference-fit piece comprising a plug.

4. The method of claim 1, wherein the filling device comprises a female interference-fit piece comprising a socket.

5. The method of claim 1, wherein pushing the filling device further comprises pushing the device with a driver.

6. A method for filling an abnormal void within the body comprising:

inserting a filling device into a closed sac volume, wherein the filling device comprises a first rotatable joint and a rigid length substantially adjacent to the rotatable joint, wherein the first rotatable joint comprises a first coiled configuration, and wherein the coiled configuration comprises a full loop, and wherein the first rotatable joint is integral with the rigid length;

pushing the filling device in the closed sac volume;

substantially filling the closed sac volume with the filling device; and

inserting a vascular prosthesis adjacent to the abnormal void, and wherein inserting the filling device further comprises deploying the filling device between a vascular wall adjacent to the closed sac volume and the vascular prosthesis.

7. The method of claim 6, wherein the rigid length comprises an uncoiled configuration adjacent to the first coiled configuration.

8. The method of claim 7, wherein the filling device further comprises a second rotatable joint comprising a second coiled configuration adjacent to the uncoiled configuration on the opposite side of the uncoiled configuration from the first coiled configuration.

9. The method of claim 8, wherein the first rotatable joint comprises a flexible leader having a first thickness.

10. The method of claim 9, wherein the rigid length comprises a rigid element having a second thickness greater than the first thickness.

11. The method of claim 6, wherein pushing the filling device further comprises pushing the device with a driver.

12. The method of claim 6, wherein the coiled configuration comprises a helical configuration.

13. The method of claim 6, wherein the full loop comprises at least one turn around the device.
