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.
