An ingestible delivery system configured to facilitate the ingestion of a gastric device by a patient, the delivery system comprising a shaped body of a bio-compatible material encasing the gastric device (402, 100) in a compressed configuration, the gastric device being releaseable from the shaped body subsequent to ingestion such that the gastric device can assume an expanded profile; characterized by: the shaped body being configured to conform to a shape of a palatal arch of the patient to reduce a gagging reflex of the patient, where the bio-compatible material is elastically deformably compliant; and the shaped body having a pharyngeal end, a first side and a second side, and a labial end, the body comprising: a bottom lingual surface having a smoothly continuous surface extending from the pharyngeal end of the body to the labial end of the body; and a top palatal surface above the bottom lingual surface, the top palatal surface having a bulge, wherein the body has a maximum thickness as measured between the top palatal surface and the bottom lingual surface at the bulge, where the top palatal surface comprises a pharyngeal tapering surface that smoothly tapers from the bulge to the pharyngeal end of the body and a labial tapering surface that smoothly tapers from the bulge to the labial end of the body, such that a thickness of the body decreases from the bulge along both the pharyngeal tapering surface and the labial tapering surface and the thickness of the shaped body decreases from the bulge towards the first and second sides of the body, wherein a length of the pharyngeal tapering surface is greater than a length of the labial tapering surface. the shaped body being configured to conform to a shape of a palatal arch of the patient to reduce a gagging reflex of the patient, where the bio-compatible material is elastically deformably compliant; and the shaped body having a pharyngeal end, a first side and a second side, and a labial end, the body comprising: a bottom lingual surface having a smoothly continuous surface extending from the pharyngeal end of the body to the labial end of the body; and a top palatal surface above the bottom lingual surface, the top palatal surface having a bulge, wherein the body has a maximum thickness as measured between the top palatal surface and the bottom lingual surface at the bulge, where the top palatal surface comprises a pharyngeal tapering surface that smoothly tapers from the bulge to the pharyngeal end of the body and a labial tapering surface that smoothly tapers from the bulge to the labial end of the body, such that a thickness of the body decreases from the bulge along both the pharyngeal tapering surface and the labial tapering surface and the thickness of the shaped body decreases from the bulge towards the first and second sides of the body, wherein a length of the pharyngeal tapering surface is greater than a length of the labial tapering surface. a bottom lingual surface having a smoothly continuous surface extending from the pharyngeal end of the body to the labial end of the body; and a top palatal surface above the bottom lingual surface, the top palatal surface having a bulge, wherein the body has a maximum thickness as measured between the top palatal surface and the bottom lingual surface at the bulge, where the top palatal surface comprises a pharyngeal tapering surface that smoothly tapers from the bulge to the pharyngeal end of the body and a labial tapering surface that smoothly tapers from the bulge to the labial end of the body, such that a thickness of the body decreases from the bulge along both the pharyngeal tapering surface and the labial tapering surface and the thickness of the shaped body decreases from the bulge towards the first and second sides of the body, wherein a length of the pharyngeal tapering surface is greater than a length of the labial tapering surface.
