Embolic protection devices having radiopaque markers

A device comprising:

• a filter element comprising a mesh, the filter element being configured to expand from a collapsed configuration to an expanded configuration, wherein, in the expanded configuration, the filter element defines a cavity having an opening;
• a radiopaque element comprising at least two discontinuous loop segments extending around a perimeter of the opening;
• an elongate support member;
• a proximal marker on the elongate support member and slidable with respect to the elongate support member;
• and
• a distal marker on the elongate support member and slidable with respect to the elongate support member, wherein the mesh of the filter element is attached to the proximal and distal markers,
• wherein the elongate support member comprises a stop between the proximal and distal markers that limits the movement of proximal and distal markers.

A device comprising:

• a filter element comprising a mesh, the filter element being configured to expand from a collapsed configuration to an expanded configuration, wherein, in the expanded configuration, the filter element defines a cavity having an opening;
• a radiopaque element comprising a discontinuous loop extending around a portion of a perimeter of the opening, the discontinuous loop being disposed around 50 to 90 percent of the perimeter of the opening;
• an elongate support member;
• a proximal marker on the elongate support member and slidable with respect to the elongate support member;
• and
• a distal marker on the elongate support member and slidable with respect to the elongate support member, wherein the mesh of the filter is attached to the proximal and distal markers,
• wherein the elongate support member comprises a stop between the proximal and distal markers that limits the movement of proximal and distal markers.
