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 comprising a nanotextured surface. 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, the spacing elements comprising a nanotextured surface;

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 at least one of silver ions, quaternary amines, or tobramycin.

6. The wound packing device of claim 1, comprising from 4 to 50 spacing elements.

17. The wound packing device of claim 1, each spacing element capable of absorbing an amount of exudate equal to at least the weight of the spacing element.

23. 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.

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

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

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

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

49. The wound packing device of claim 1, further comprising a layer of graphene disposed over the spacing elements.

50. The wound packing device of claim 1, further comprising a layer of graphene disposed over the spacing elements, further comprising a modifying agent covalently bonded to the graphene.

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

65. The wound packing device of claim 64, wherein the color of the spacing elements changes according to the amount of exudate absorbed.

67. The wound packing device of claim 1, further comprising a modifying agent covalently bonded to the surface of the spacing elements.

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

69. The wound packing device of claim 1, the nanotextured surface comprising a nanometer scale surface geometry sufficient to inhibit adherence of bacterial cells to the nanotextured surface.

70. The wound packing device of claim 1, the nanotextured surface comprising a nanometer scale surface geometry sufficient to inhibit adherence of bacterial cells to the nanotextured surface.
