Scaffold comprising co-precipitated Collgen and glycosaminoglycan for inhibiting adhesion of body tissue layers

摘要

A device for inhibiting adhesion of apposing human body tissue layers includes a scaffold having a designated mean pore size, relative density, and degradation half-life. The scaffold may be operably positioned between apposing tissue layers, such as proximate adhesiogenic layers at a wound site, so as to permit remesothelialization of the tissue without formation of fibrous adhesions. The scaffold device of the invention inhibits adhesion formation by promoting contractile cell migration away from the wound site for a predetermined period of time. The invention further relates to device and methods for promoting internal tissue regeneration, and for provision and/or dispensation of therapeutic and/or diagnostic agents in vivo.
