Abstract

An expandable spherical structure for deployment in a blood vessel or other body lumen, comprising: an open frame configured to assume a collapsed configuration and an expanded configuration; and a closed face carried by the open frame; wherein the open frame is configured so as to permit substantially normal flow therethrough when the open frame is in its expanded configuration, and further wherein the closed face is configured so as to obstruct flow therethrough.
