ABSTRACT:
A dressing for a wound having 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 has pores defined by the filmy interconnections. In other words, the wound dressing has a continuous open-celled structure in an expanded foam. The wound dressing can advantageously be made of a highly biocompatible material, such as poly-.alpha.-amino acid.
