Aspiration system with accelerated response

An aspiration system with accelerated response, comprising:

• an aspiration pump in communication with a first chamber;
• an aspiration catheter configured for placement into fluid communication with the first chamber by way of an aspiration tube;
• a second chamber in between the aspiration tube and the catheter, the second chamber being configured to capture a clot aspirated by the catheter, wherein at least a portion of the second chamber is removably carried by a handle;
• and
• a valve between the second chamber and the aspiration catheter;
• wherein upon opening of the valve with negative pressure in the first and second chambers, resistance to fluid flow between the second chamber and a distal end of the catheter is less than the resistance to fluid flow between the second chamber and the first chamber, causing a rapid aspiration into the second chamber.

• a second chamber in between the aspiration tube and the catheter;
• a valve between the second chamber and the aspiration catheter;
• and
• an operator actuated control, configured to toggle a flow regulator between a default low flow mode, and a momentary, operator initiated high flow override mode;
• wherein upon opening of the valve with negative pressure in the first and second chambers, resistance to fluid flow between the second chamber and a distal end of the catheter is less than the resistance to fluid flow between the second chamber and the first chamber, causing a rapid aspiration into the second chamber.

• wherein the second chamber is configured for location within a sterile field, and the first chamber is configured for location outside of the sterile field.
