摘要：
A device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body. The device including a filter element being expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, and an elongate support member, the filter being carried on a portion of the elongate support member. The filter element has proximal and distal portions and a central portion, the filter element having a shape in the expanded configuration which defines a cavity having a proximal facing opening, and the proximal portion of the filter element includes a radiopaque element in the form of a discontinuous loop extending around a portion of a perimeter of the proximal facing opening, the discontinuous loop having a gap and the gap being proximate to the elongate support member.
