Abstract
A permeable plug may be temporarily deployed in a patient to protect blood vessels from blockage by various debris. The plug includes a body formed from a filtering material. The body is collapsible for delivery to a location in a blood vessel and expandable to a filtering configuration in which the body occupies a cross-section of the blood vessel and is held in place by its own expansive force. At least one stud is connected to the body for use in deployment of the plug within the blood vessel and retrieval of the plug from the blood vessel.
