Abstract:
1. A gastro-retentive agent delivery device for oral intake, the device configured for unfolding from a folded configuration for oral intake to an unfolded configuration for gastric retention, the device comprising: two external layers sandwiching a functional layer therebetween; the functional layer comprising at least one layer comprising an agent or agent-releasing formulation; the functional layer being configured for imparting mechanical strength to the device sufficient to enable, upon unfolding of the device, the preservation of said unfolded configuration to provide gastric retention; at least one said external layer comprising perforations, wherein in the folded configuration the device has a plurality of folds and a device axis, said folds being of increasingly smaller amplitudes upon extending away from the device axis so as to form a partially rounded cross section.
