Proximal embolic protection device for carotid stenting

A catheter, comprising:

• a proximal catheter segment extending from a proximal region to a distal region including a distal end, the proximal catheter segment adapted to terminate with its distal end within a common carotid artery (CCA), the proximal catheter segment having an 8 French outer diameter;
• a distal catheter segment extending from a proximal end to a region including a distal end, the distal catheter segment extending distally from the distal end of the catheter body, the distal catheter segment adapted to terminate within an external carotid artery (ECA);
• a working lumen extending through the proximal catheter segment and terminating at the distal end of the proximal catheter segment, the working lumen having a 6 French inner diameter;
• a CCA occlusion element secured within the distal region of the catheter body;
• an ECA occlusion element secured within the distal region of the distal catheter segment;
• and
• a blood shunt path extending from a position proximal of the CCA occlusion element to a position distal of the ECA occlusion element in order to allow antegrade blood flow from proximal of the inflatable CCA occlusion balloon to distal of the inflatable ECA occlusion balloon.

A reverse flow medical device combination for performing carotid artery stenting, the reverse flow medical device combination comprising:

• a first catheter including:
• a catheter body extending from a proximal region to a distal region including a distal end, the catheter body adapted to terminate with its distal end within a common carotid artery (CCA);
• a working lumen extending through the catheter body and terminating at the distal end of the catheter body;
• a first inflatable balloon secured within the distal region of the catheter body of the first catheter and adapted when inflated to occlude the CCA;
• and
• a second catheter including:
• a catheter body extending from a proximal region to a distal region including a distal end, the catheter body adapted to terminate with its distal end within an internal carotid artery (ICA);
• an expandable stent disposed over the catheter body;
• a second inflatable balloon secured within the distal region of the catheter body of the second catheter;
• a blood lumen extending through the catheter body to a position distal of the second inflatable balloon in order to allow antegrade blood flow from a position proximal of the first inflatable balloon to a position distal of the second inflatable balloon.
