Aspiration control valve

An apparatus comprising:

• a distal port comprising a resizable seal configured to open to receive a catheter and close to hemostatically seal and grip an exterior perimeter of the catheter;
• a proximal port sized to allow passage of an inner elongated member, the inner elongated member disposed within a lumen of the catheter;
• a first side port;
• a first flow path extending from the lumen of the catheter to the first side port;
• a control valve in communication with the lumen of the catheter and the first side port, the control valve comprising a tubing compressible to control blood flow through the first flow path;
• and
• a control interface in communication with the control valve and configured to compress the tubing, the control interface comprising at least two positions, the at least two positions corresponding to at least two flow rates of the blood flow through the first flow path and corresponding to at least two distinct compressions of the tubing.
