Epithelialization methods, dressings, and systems

摘要

Methods, dressings, and systems for promoting epithelialization of a wound or other tissue are presented. The methods, dressings, and systems help form simulated rete pegs. In one instance, an epithelialization dressing is disclosed that may include a dressing body having a plurality of projections. A plurality of apertures is formed on a portion of the dressing body. The dressing helps manage fluids on the wound and the projections form cavities into which epithelial tissue migrates to from epithelial columns that function like rete pegs. Other dressings, methods, and systems are disclosed.

主权项

1. A method for treating a wound having granulation tissue in a wound bed, the method comprising the steps of:
deploying an epithelialization dressing proximate the granulation tissue in the wound bed, wherein the epithelialization dressing comprises:
a dressing body having a first side and a second, tissue-facing side, wherein the dressing body comprises a plurality of apertures, each of the apertures disposed through the first side and the second, tissue-facing side, anda plurality of projections, each projection having a proximal end and a distal end, the distal end having a plurality of pores, the proximal end coupled to the second, tissue-facing side of the dressing body between the plurality of apertures; causing a compression force on the epithelialization dressing such that the plurality of projections impinge upon the granulation tissue; and allowing sufficient time for epithelium tissue to form proximate the projections.
