Abstract
A hemostatic insert is provided for closing a puncture site in a blood vessel wall. The insert includes an expandable hemostatic member comprising a biocompatible water soluble gel configured to expand from a compressed state when exposed to body fluid and seal the puncture site in the blood vessel wall. A control layer surrounds the hemostatic member and delays expansion of the hemostatic member.
