Abstract
An embolic protection device includes an expandable and contractible filter that can be supported by one or more struts. The struts can be connected to the filter or interwoven into the filter, so as to assist in the expansion and contraction of the filter. In one embodiment, the proximal ends of the struts connect to a joint that is fixed in position relative to a delivery wire, while the distal end of the filter connect to a joint that slides relative to the delivery wire.
