Abstract

The provided technologies provide an implant closure device having a mesh layer formed on a flexible substrate, collectively forming a sealable member, that improves a seal formed over an aperture in a body lumen. The mesh facilitates a faster and more secure adherence of the sealable member to the surrounding edges at the puncture site. Furthermore, the provided technology may promote platelet-capture and encourage localized platelet aggregation at the exposed collagen in the wound edges on the mesh layer. The platelet impregnated mesh layer can facilitate cellular adhesion, enabling the sealable member that is local to the wound opening to act, in essence, as a “biological glue.”
