摘要：
An expandable substantially spherical structure fordeployment in a blood vessel or other body lumen is disclosed.The structure has an open frame formed out of a closed loop offilament and configured to assume (i) a collapsed configurationin the form of a substantially two-dimensional elongated loopstructure so as to facilitate insertion into the blood vesselor other body lumen, and (ii) an expanded configuration in theform of a three-dimensional substantially spherical structureso as to facilitate retention at a site in the blood vessel orother body lumen. The structure also has a flow-restrictingface carried by the open frame. The open frame is configured topermit substantially normal flow therethrough when the openframe is in its expanded configuration, and further the flow-restrictingface is configured to restrict flow therethrough.
