Abscess drainage

1. A drainage device for holding an incision in an abscess of a subject open to allow drainage of fluid out of the abscess, the drainage device comprising an elongate body, a first extension member extending laterally from the elongate body and disposed at a first longitudinal end of the elongate body, and a second extension member extending laterally from the elongate body and disposed at a second longitudinal end of the elongate body, the first and second extension members extending from the elongate body to respective free ends of the extension members along a linear plane, wherein the first and second extension members are disposed at the respective first and second longitudinal ends such that an entire length of the elongate body extends between the first and second extension members, the length of the elongate body being longer than lengths of the first and second extension members, the elongate body being configured for insertion into the abscess, and the first and second extension members being configured to retain at least a portion of the elongate body in the abscess, the elongate body facilitating drainage of fluid out of the abscess, wherein the elongate body is free of a passage extending through an interior of the elongate body such that in use a portion of the device is disposed within the abscess and a portion of the device is disposed outside of the abscess and outside of the subject whereby the drainage of fluid flows around the elongate body when the drainage device is inserted into the abscess, wherein the elongate body and extension members are formed entirely from silicone.

2. The drainage device of claim 1 wherein each extension member comprises a first extension arm extending laterally from the elongate body in a first direction, and a second extension arm extending laterally from the elongate body in a second direction different from the first direction.

3. The drainage device of claim 1 wherein each extension member extends orthogonally from the elongate body.

4. The drainage device of claim 3 wherein each extension member comprises a first extension arm extending orthogonally from the elongate body in a first direction, and a second extension arm extending orthogonally from the elongate body in a second direction opposite the first direction.

5. The drainage device of claim 1 wherein each extension member has a circular cross section.

6. The drainage device of claim 1 wherein the elongate body has an elliptically shaped cross-section providing the drainage device with a low profile.

7. The drainage device of claim 1 wherein the elongate body has a rectangular cross section.

8. The drainage device of claim 1 wherein the elongate body and the first and second extension members together provide the drainage device with an I-shaped configuration.

9. The drainage device of claim 1 further comprising a third extension member extending laterally from the elongate body and disposed between the first and second extension members.

10. The drainage device of claim 9 wherein there are only three extension members, the extension members being non-uniformly spaced along the length of the elongate body.

11. The drainage device of claim 9 further comprising a fourth extension member extending laterally from the elongate body and a fifth extension member extending laterally from the elongate body, the fourth and fifth extension members being disposed between the first and second extension members, the extension members being uniformly spaced along the length of the elongate body.

12. The drainage device of claim 1 wherein longitudinal ends of the elongate body are closed.

13. The drainage device of claim 1 , wherein the elongate body has a cross-sectional shape different from a cross-sectional shape of the extension members.

14. A drainage device for holding an incision in a mass of a subject open to allow drainage of fluid out of the mass, the drainage device comprising an elongate body and an extension member extending laterally from the elongate body to a free end of the extension member a distance greater than a width of the elongate body and along a linear plane, the elongate body having a length that is longer than a length of the extension member, the elongate body and extension member being integrally formed from a single piece of material, the elongate body being configured for insertion into the mass such that in use a portion of the device is disposed within the mass and a portion of the device is disposed outside of the mass and outside of the subject, and the extension member being configured to retain at least a portion of the elongate body in the mass, the elongate body facilitating drainage of fluid out of the mass, wherein the elongate body and extension member are formed entirely from silicone.

15. The drainage device of claim 14 wherein the elongate body and extension member comprise a single molded piece of material.

16. A drainage device for holding an incision in a mass of a subject open to allow drainage of fluid out of the mass, the drainage device comprising an elongate body and an extension member extending laterally from the elongate body to a free end of the extension member along a linear plane, the elongate body having longitudinal ends that are closed, the elongate body having a length that is longer than a length of the extension member, the elongate body and extension member being integrally formed from a single piece of material, the elongate body being configured for insertion into the mass such that in use a portion of the device is disposed within the mass and a portion of the device is disposed outside of the mass and outside of the subject, and the extension member being configured to retain at least a portion of the elongate body in the mass, the elongate body facilitating drainage of fluid out of the mass, wherein the elongate body and extension member are formed entirely from silicone.
