Cyclic aspiration system producing a cyclic aspiration pressure waveform using a dual pressure generator receptacle in lieu of a vacuum pump

A method for using a cyclic aspiration system for producing a cyclic aspiration pressure waveform of intermittent cycles of vacuum pressure below atmospheric pressure and positive pressure higher than vacuum pressure;

• the cyclic aspiration system comprising:
• an aspiration catheter having a proximal end and an opposite distal end;
• and a dual pressure generator receptacle disposed proximally of and connected in fluid communication with the aspiration catheter;
• wherein the method comprises the steps of:
• delivery of the aspiration catheter through a vessel to a target site on a proximal side of a clot;
• and
• producing the cyclic aspiration pressure waveform using the dual pressure generator receptacle by intermittently cyclically subjecting a collectable fluid receivable therein to application or withdraw of a compressible force via a linear displacement mechanism;
• the positive pressure being generated while the collectable fluid in the dual pressure generator receptacle is subject to the compressive force and the vacuum pressure being generated while the collectable fluid in the dual pressure generator receptacle is not subject to the compressive force;
• wherein the cyclic aspiration pressure waveform is producible via the dual pressure generator receptacle without a separate vacuum pump.
