Abstract

Embodiments of the invention include wound packing devices and methods of making and using the same. In an embodiment, the invention includes a wound packing device including a plurality of spacing elements capable of absorbing exudate, wherein the surface of the spacing elements resist colonization by microorganisms. The wound packing device can also include a connector connecting the plurality of spacing elements to one another. Other embodiments are also included herein.

Claims

1. A wound packing device comprising:

a plurality of spacing elements, wherein a surface of the spacing elements resists colonization by microorganisms; and

wherein the spacing elements are hollow;

a connector connecting the plurality of spacing elements to one another; and

wherein the plurality of spacing elements are capable of absorbing exudate.

2. The wound packing device of claim 1, the surface of the spacing elements exhibiting antimicrobial activity.

3. The wound packing device of claim 1, the surface of the spacing elements comprising one or more of silver ions, quaternary amines, and tobramycin.

4. The wound packing device of claim 1, wherein the spacing elements are swellable.

5. The wound packing device of claim 1, the spacing elements comprising a core and an outer layer disposed on the outside surface of the core, the outer layer comprising a water permeable material.

6. The wound packing device of claim 1, the spacing element comprising a plurality of pores.

7. The wound packing device of claim 1, the spacing element comprising a fluid sequestering agent.

8. The wound packing device of claim 1, further comprising a lubricious coating disposed on the spacing elements.

9. The wound packing device of claim 1, further comprising a lubricious coating disposed on the connector.

10. The wound packing device of claim 1, further comprising an RFID device.

11. The wound packing device of claim 1, wherein the spacing elements are inflatable.

12. The wound packing device of claim 11, wherein an antimicrobial agent is disposed within the inflatable spacing elements.

13. The wound packing device of claim 1, wherein the spacing elements are colored, including at least two different colors amongst the spacing elements.

14. The wound packing device of claim 13, wherein the color of the spacing elements changes according to the amount of exudate absorbed.

15. The wound packing device of claim 1, further comprising a radiopaque material.

16. A wound packing device comprising:

a plurality of spacing elements, wherein a surface of the spacing elements resists colonization by microorganisms;

a connector connecting the plurality of spacing elements to one another, the connector comprising a plurality of segments that are interconnected to one another through a friction fit mechanism; and

wherein the plurality of spacing elements are capable of absorbing exudate.

17. A wound packing device comprising:

a plurality of spacing elements, wherein a surface of the spacing elements resists colonization by microorganisms;

a plurality of hollow fibers disposed within the spacing elements;

a connector connecting the plurality of spacing elements to one another; and

wherein the plurality of spacing elements are capable of absorbing exudate.

18. A wound packing device comprising:

a plurality of spacing elements, wherein a surface of the spacing elements resists colonization by microorganisms;

a connector connecting the plurality of spacing elements to one another;

a metal disposed within the spacing elements or the connector, the metal comprising a ferrous metal; and

wherein the plurality of spacing elements are capable of absorbing exudate.
