Angiography Catheter

An embolic protection device comprising:

• a catheter having a proximal end, a distal end, and a lumen extending from the proximal end of the catheter to the distal end of the catheter, the lumen configured to house a guidewire, a distal portion of the catheter configured to assume a generally arcuate shape being at least a semi-circle;
• the distal portion of the catheter comprising a longitudinally-extending radiopaque marker configured to be arcuate and on a distal-most section of the catheter when the distal portion is in the generally arcuate shape;
• a self-expanding embolic filter coupled to the catheter proximal to the distal portion, the embolic filter having a generally conical shape, the embolic filter comprising a distal opening and extending proximally from the distal opening to a closed proximal end;
• and
• a deployment mechanism circumferentially around at least a portion of the catheter and longitudinally movable with respect to the catheter, the deployment mechanism configured to contain the embolic filter in a collapsed configuration, and the embolic filter configured to self-expand upon longitudinal proximal retraction of the deployment mechanism.

An embolic protection device comprising:

• a catheter having a proximal end and a distal end;
• a self-expanding embolic filter coupled to a side of the catheter, the embolic filter comprising a distal opening and extending proximally from the distal opening to a closed proximal end in a generally conical shape;
• and
• an outer sheath longitudinally movable with respect to the embolic filter, the outer sheath configured to contain the embolic filter in a collapsed state when at least partially around the embolic filter, and the embolic filter configured to self-expand upon longitudinal proximal retraction of the outer sheath.
