Embolization device and a method of using the same
View Patent ↗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.
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.
