A biosorbable oxygen-delivery wound treatment device that includes a biosorbable matrix for delivering oxygen. The biosorbable matrix includes a water swellable, cross-linked biosorbable polymer network. A plurality of gas-permeable, elastic, closed cells is defined by the cross-linked biosorbable polymer network. According to the invention, these closed cells may be produced from a reaction between a catalyst and a second reactant. Deliverable oxygen is contained within the elastic closed cells such that when the device is used to treat a wound, oxygen is delivered from the closed cells. A process for making a biosorbable oxygen-delivery wound treatment device that includes a biosorbable matrix for delivering oxygen as well as a method of using an oxygen-delivery wound treatment device is disclosed.
