Abstract: A tissue puncture locator device includes a temporary anchor configured for placement through a vascular puncture into a vessel. The temporary anchor includes a column member that defines a lumen. The temporary anchor is movable between an uncompressed position and a compressed position, wherein in the compressed poition a portion of the column member protrudes radially outward. The column member may include a reduced thickness portion, wherein the column member protrudes radially outward at the reduced thickness portion. The column member, when expanded radially outward within the vessel, is sized to limit retraction of the temporary anchor through the vascular puncture.

Abstract: Various embodiments of methods for closing vascular holes and associated vascular closure devices are described herein. The methods, generally speaking, use hemostatic devices intended to stop bleeding by closing vascular access puncture sites following percutaneous diagnostic or therapeutic procedures. The methods may include positioning a sealing plug in the vascular hole. In one embodiment, the sealing plug may extend through the vascular hole into the vessel. The sealing plug may expand and thereby create a lip inside the vessel that holds the sealing plug in place.
