Abstract

A silicone foam is described that is produced in-situ at a wound site, e.g. in a wound cavity, through a multi-component system, based on a physical foaming process, wherein the gas required to form the foam structure is provided through a blowing agent independently of the curing reaction of polyorganosiloxane components of the multi-component system. Therefore, the blowing agent is provided as a distinct entity of the multi-component system that is, in particular, not the result of any chemical reaction taking place in the multi-component system. A device for producing the foam and the corresponding negative pressure wound therapy kit are also described.
