1. An embolic protection device, comprising:
a) a scaffold, comprising:
i) a proximal eyelet extending along an eyelet axis;
ii) a frame adapted to operate between expanded and collapsed profiles, wherein the frame comprises:
A) a proximal strut region comprising a plurality of proximal struts extending distally from the proximal eyelet;
B) a frame-cell region having a frame-cell region length extending distally from a frame-cell region proximal edge to a frame cell region distal edge, wherein the frame-cell region proximal edge is continuous with the proximal strut region; and
b) a conical filter supported by the frame, the conical filter consisting of:
i) an imperforate section extending distally from an imperforate section proximal edge spaced from an imperforate section distal portion, wherein the imperforate section proximal edge defines an ingress into the conical filter; and
ii) a porous section configured for fluid flow therethrough, the porous section extending distally from the imperforate section distal portion to terminate at a porous section distal end, wherein, other than being connected to the porous section, the porous section distal end is an unsupported distal end of the embolic protection device,
c) wherein the imperforate section of the conical filter is coupled to the frame-cell region proximal edge and extends at least part-way along the frame-cell region length toward the frame-cell distal edge, or the imperforate section is coupled to the frame-cell region distal edge and extends part-way along the distal strut region length, and
d) wherein, other than the conical filter, the embolic protection device does not have another filter.
