Abstract
Provided are metal cores for gastric residence system and gastric residence systems comprising metal cores. A metal core according to some embodiments includes a plurality of arm mounts, each arm mount configured to receive an elongate arm of a gastric residence system, wherein the core is configured to bend into a compacted form such that each arm mount of the plurality of arm mounts approach each other and, when a plurality of elongate arms are attached to the metal core, the distal ends of the plurality of elongate arms approach each other, and wherein the metal of the metal core provides elasticity and shape memory to cause the metal core to unfold into an uncompacted form and, when a plurality of elongate arms are attached to the metal core, allow retention of the gastric residence system.
