Abstract

A method and apparatus for filling a cavity in a patient'"'"'s body with a material are provided. The apparatus can include a flexible tube, a barrel and a plunger. The flexible tube has a first end, a second end, and a lumen extending from the first end to the second end and operable to hold a material for conveyance through the first end into a cavity. The barrel is in fluid communication with the second end of the flexible tube and includes a lumen configured to receive material for delivery into the flexible tube. The plunger is configured to advance material through the lumen in the barrel and into the flexible tube. In one implememtation, there is substantially a one to one ratio of advancement of the plunger to a volume of material advanced from the rigid first end of the flexible tube.

8. The apparatus of claim 4, wherein:

an assembly of the flexible tube connected to the barrel is pre-loaded with the material; and

the plunger is operable to advance at least some of the pre-loaded material into the cavity.

9. The apparatus of claim 1, the barrel further comprising:

a plurality of lumens disposed in the barrel and configured to receive material for delivery into the flexible tube,

wherein, the barrel is rotatable about a longitudinal axis of the barrel and where each lumen of the plurality of lumens is preloaded with material, such that once a lumen has been emptied into the flexible tube by action of the plunger, the plunger can be withdrawn, the barrel can be rotated and the plunger can engage a next lumen to fill the flexible tube.

10. The apparatus of claim 1, further comprising:

a cartridge configured to receive material for delivery into the flexible tube,

wherein, the lumen is configured to receive the cartridge and to receive the material via the cartridge, and the plunger is configured to advance material through the lumen in the barrel via advancement through the cartridge.

11. An apparatus comprising:

a flexible tube having a rigid first end, a second end, and a lumen extending from the first end to the second end and operable to hold a material for conveyance through the rigid first end and into a cavity;

a barrel in fluid communication with the second end of the flexible tube, the barrel including a lumen configured to receive material for delivery into the flexible tube, where the barrel'"'"'s lumen has a diameter substantially the same as a diameter of the flexible tube'"'"'s lumen; and

a plunger configured to advance material through the lumen in the barrel and into the flexible tube.

12. The apparatus of claim 11, further comprising:

a cannula having a first end configured to receive the first end of the flexible tube and having a second end configured to provide the first end of the flexible tube access to the cavity.

13. The apparatus of claim 11, wherein:

the lumen of the flexible tube is pre-loaded with the material; and

the plunger is operable to advance material through the lumen in the barrel into the flexible tube and advance the pre-loaded material in the flexible tube through the lumen in the flexible tube and into the cavity.

14. The apparatus of claim 11, further comprising:

a connector connecting the flexible tube to the barrel, where the flexible tube is connected to the barrel such that a longitudinal axis of the barrel is at an angle in the range of approximately 0°

to approximately 90°

to a longitudinal axis of the flexible tube.

15. The apparatus of claim 14, wherein the angle is substantially 40°

to 50°

.

16. The apparatus of claim 14, wherein the connector is a luer fitting.

the barrel includes threads on an end of the lumen; and

the connector further comprises threads configured to mate with the threads on the barrel.

18. The apparatus of claim 14, wherein:

an assembly of the flexible tube connected to the barrel is pre-loaded with the material; and

the plunger is operable to advance at least some of the pre-loaded material into the cavity.

19. An apparatus comprising:
