Abstract

Disclosed herein are devices, systems, and methods for aspirating clot material and blood from the vasculature of a patient, filtering the blood from the clot material, and returning the filtered blood to the vasculature of the patient. In some embodiments, a system in accordance with the present technology can include (i) an aspiration catheter configured to be positioned within the vasculature of a patient proximate to clot material therein, (ii) a reinfusion catheter configured to be positioned within the vasculature, (iii) a collection chamber selectively fluidly coupled to the aspiration catheter and the reinfusion catheter, (iv) a pump assembly selectively fluidly coupled to the collection chamber and configured to generate positive and negative pressure within the collection chamber, and (v) a control system configured to selectively control the fluid couplings to perform clot aspiration and filtered blood reinfusion operations.
