Claims
- 1. A dressing for a wound comprising a porous structure of continuous pores throughout the dressing made of minute filaments arranged in three dimensions, and filmy links, viewed at a magnification of about 35 to 350, connecting the filaments, the porous structure having pores defined by the filmy interconnections.
- 2. A dressing for a wound as defined in claim 1, wherein the pores are continuous in the porous structure and connected to other pores by the filmy links; the dressing further comprising a wound-facing surface, an opposing surface and a volume disposed therebetween; the pores of the wound-facing surface and of the volume, respectively, being greater in number and larger than the pores of the opposing surface.
- 3. A dressing for a wound as defined in claim 1, wherein the porous structure is made of poly-.alpha.-amino acid.
- 4. A dressing for a wound as defined in claim 1, further comprising an antimicrobial agent.
- 5. A dressing for a wound as defined in claim 2, wherein the pores for the wound-facing surface and of the volume have a diameter of about 20 to 500 .mu.m, and the pores of the opposing surface have a diameter up to about 20 .mu.m.
- 6. A dressing for a wound as defined in claim 5, wherein the dressing has a thickness of about 0.1 to 10 mm and the opposing surface has a thickness of about 0.5 to 5 .mu.m.
- 7. A dressing for a wound as defined in claim 1, further comprising a mesh of reinforcing material embedded in the porous structure.
- 8. A dressing for a wound as defined in claim 7, wherein the reinforcing material forms a border to the dressing, the pores on the wound-facing surface are smaller than the pores of the opposing surface.
- 9. A dressing for a wound as defined in claim 1, further comprising a plurality of perforations in the dressing between the wound-facing surface and the opposing surface.
- 10. A dressing for a wound comprising a porous structure of continuous pores throughout the dressing made of minute filaments arranged in three dimensions, and filmy links, viewed at a magnification of about 35 to 350, connecting the filaments, the porous structure having pores defined by the filmy interconnections and a mesh of reinforcing material embedded in the porous structure.
