Abstract: A catheter control system can include a guide catheter that has a distal end configured to be positioned within an artery. The system can include a guide extension catheter positioned within the guide catheter and configured to extend from the distal end of the guide catheter and a catheter control center at a proximal end of the guide catheter. The catheter control center can include a guide extension advancement mechanism. The guide extension advancement mechanism is in communication with the guide extension catheter and is configured to move the guide extension catheter within the guide catheter and extend the guide extension catheter from the distal end of the guide catheter. The catheter control center can include a valve at a proximal end of the catheter control center configured to allow passage of wires and/or devices between the valve and guide catheter.A catheter control system can include a guide catheter that has a distal end configured to be positioned within an artery.
