Investigators have designed a drug-delivery vehicle that consists of six arms joined by an elastic-coated core. The arms were loaded with the oral contraceptive drug levonorgestrel and folded up into a capsule that can be swallowed. Once in the stomach, the arms unfold and have a span that is larger than the opening of the human pylorus, helping the system stay in the stomach where it can release the drug over time.
