Abstract

A drainage device comprising a) a drain comprising a proximal end, a distal end and a central lumen; and b) an occlusion removing structure within the central lumen of the drain comprising a proximal end and a distal end; where the proximal end of the drain comprises an adaptor; where the distal end of the drain comprises a plurality of apertures; where the proximal end of the occlusion removing structure is a connector configured to mate with the adaptor; where the distal end of the occlusion removing structure is a tubular mesh; where the tubular mesh extends substantially throughout the length of the drain from the proximal end of the drain, to the distal end of the drain; and where the occlusion removing structure is axially removable from the drain.

Claims

1. A drainage device comprising:

a) a drain comprising a proximal end, a distal end and a central lumen; and

b) an occlusion removing structure within the central lumen of the drain comprising a proximal end and a distal end;

where the proximal end of the drain comprises an adaptor;

where the distal end of the drain comprises a plurality of apertures;

where the proximal end of the occlusion removing structure is a connector configured to mate with the adaptor;

where the distal end of the occlusion removing structure is a tubular mesh;

where the tubular mesh extends substantially throughout the length of the drain from the proximal end of the drain to the distal end of the drain; and

where the occlusion removing structure is axially removable from the drain.

2. The drainage device of claim 1, where the tubular mesh is connected directly to the connector of the occlusion removing structure.

3. The drainage device of claim 1, further comprising a suction device mated with the adapter.

4. The drainage device of claim 1, where the proximal end of the drain comprises a cap.

5. The drainage device of claim 1, where the drain further comprises one or more than one loop attached to the outer surface of the proximal end for securing the proximal end of the device.

6. The drainage device of claim 1, where the device further comprises a sealant separate from the drain and from the occlusion removing structure for sealing the connector to the adaptor.

7. The drainage device of claim 1, where the occlusion removing structure is a first occlusion removing structure, and where the device further comprises a second occlusion removing structure comprising a proximal end, a distal end, an intermediate segment between the proximal end and the distal end, and an inflation balloon on the distal end of the second occlusion removing structure.

8. A method of unoccluding a drainage device comprising:

a) providing the drainage device of claim 1;

b) placing the distal end of the drain into an area to be drained;

c) allowing occluding material to occlude the drain; and

d) removing the occlusion removing structure from the drain, thereby unoccluding the drain.

9. The method of claim 8, further comprising attaching the drainage device to a suction device after placing the distal end of the drain.

10. The method of claim 9, further comprising reattaching the drainage device to the suction device after removing the occluding material removing structure.

11. The method of claim 8, further comprising replacing the occlusion removing structure in the drain after unoccluding the drain.

12. The method of claim 8, where replacing the occlusion removing structure in the drain after unoccluding the drain comprises advancing an introducer containing the replacement occlusion removing structure through the proximal end of the drain until the distal end of the replacement occlusion removing structure is placed at or near the distal end of the drain, and then removing the introducer leaving the replacement occlusion removing structure.
