Apparatus and methods for controlled clot aspiration

An aspiration system for removing a clot via aspiration thrombectomy, the aspiration system having a plurality of components comprising:

• a plurality of aspiration catheters, each aspiration catheter having a proximal end and a distal end, wherein the distal end of each aspiration catheter is configured to be introduced through a vasculature of a patient to interface with a clot in the vasculature, wherein the proximal end of each aspiration catheter comprises a lumen configured to accommodate fluid, wherein each aspiration catheter comprises a catheter hub associated with the proximal end of the aspiration catheter, wherein each aspiration catheter is associated with one or more catheter parameters corresponding to the aspiration catheter, wherein one or more of the catheter parameters associated with each aspiration catheter is a catheter size or a catheter diameter of the respective aspiration catheter, and wherein the plurality of aspiration catheters comprise aspiration catheters corresponding to a plurality of different catheter sizes or catheter diameters;
• a console of the aspiration system, wherein the console comprises a physical frame configured to support one or more of the aspiration system components, wherein the physical frame comprises one or more apertures accessible to one or more of the components of the aspiration system;
• a vacuum canister configured to collect material extracted by the aspiration system, wherein the vacuum canister is physically coupled to the physical frame of the console, wherein a physical frame of the vacuum canister comprises substantially transparent material configured for the collected material in the vacuum canister to be externally visible;
• a vacuum source configured to deliver vacuum to the aspiration catheter, wherein the vacuum source comprises a vacuum pump, wherein the vacuum pump is housed in the console of the aspiration system, and wherein the vacuum source is fluidically connected to the aspiration catheter and the vacuum canister;
• a fluid source configured to deliver pressure to the aspiration catheter, wherein the fluid source is external to the console of the aspiration system, and wherein the fluid source is fluidically connected to the aspiration catheter;
• a plurality of controllable actuators of the aspiration system, wherein the plurality of controllable actuators comprise one or more first actuators associated with the vacuum source, wherein the one or more first actuators are configured to be operated to deliver specific amounts of vacuum to the aspiration catheter, wherein the plurality of controllable actuators further comprise one or more second actuators associated with the fluid source, and wherein the one or more second actuators are configured to be operated to deliver specific amounts of pressure to the aspiration catheter;
• a set of tubing comprising one or more portions of connection tubing, wherein the tubing set is configured to fluidically connect the vacuum source, the vacuum canister, the fluid source, and the aspiration catheter, and wherein an endpoint of the tubing set is configured to interface with the catheter hub associated with the proximal end of the aspiration catheter;
• and
• a controller of the aspiration system configured to:
• determine that a first aspiration catheter of the plurality of aspiration catheters is connected to the tubing set based on one or more catheter parameters associated with the first aspiration catheter;
• and
• operate the plurality of controllable actuators, based on one or more of the catheter parameters associated with the first aspiration catheter, by utilizing an algorithm associated with the aspiration system to adjust one or more operating parameters associated with the controllable actuators, to deliver an amount of aspiration power at the distal end of the first aspiration catheter, wherein the amount of aspiration power comprises one or more levels of vacuum or pressure applied at the distal end of the first aspiration catheter, and wherein the amount of aspiration power is determined based on the algorithm.
