Abstract
Among other things, there are shown embodiments of internal members for closure of vascular wall or other bodily openings, particularly useful in closing larger holes (e.g. larger than 10 French). Embodiments create a better seal or meeting with a vascular or other tissue wall by distributing force outward from the center, and/or by including rib, groove or hinge features that allow the internal member, as it is pulled toward tissue, to close the hole and engage tissue more closely or firmly.
