Tissue dressing assemblies are formed from hydrophilic polymer sponge structures. The tissue dressing assemblies can be used, e.g., (i) stanch, seal, or stabilize a site of tissue injury, tissue trauma, or tissue access; or (ii) form an anti-microbial barrier; or (iii) form an antiviral patch; or (iv) intervene in a bleeding disorder; or (v) release a therapeutic agent; or (vi) treat a mucosal surface; or (vii) combinations thereof. The tissue dressing structures are made compliant, e.g., by (i) micro-fracturing of a substantial portion of the sponge structure by mechanical manipulation prior to use, or (ii) a surface relief pattern formed on a substantial portion of the sponge structure prior to use, or (iii) a pattern of fluid inlet channels formed in a substantial portion of the sponge structure prior to use, or (iv) the impregnation of a sheet material within the sponge structure. ® KIPO & WIPO 2007
