Claim:
1. A method of manufacturing a device, comprising: forming in vitro a first film-layer from a first composition comprising solid fibrinogen and a first amount of non-aqueous solvent by processing the first composition for a first time interval required to substantially eliminate the first amount of non-aqueous solvent, the first film-layer exhibiting a first characteristic in vivo; and bonding in vitro a second film-layer to the first film-layer, the second film-layer formed from a second composition comprising solid fibrinogen and a second amount of non-aqueous solvent by processing the second composition for a second time interval required to substantially eliminate the second amount of non-aqueous solvent, the second film-layer exhibiting a second characteristic in vivo, wherein the first time interval is different from the second time interval and the first characteristic is different from the second characteristic, and the first composition is substantially identical to the second composition, except the first amount of non-aqueous solvent is different from the second amount of non-aqueous solvent.
