Abstract

The present technology relates to systems and methods for removing a thrombus from a blood vessel of a patient. In some embodiments, the present technology is directed to systems including an elongated catheter having a distal portion configured to be positioned within the blood vessel of the patient, a proximal portion configured to be external to the patient, and a lumen extending therebetween. The system can also include an imaging element at the distal portion, an illumination source at the distal portion, a capture element at the distal portion and configured to engage the thrombus, a fluid delivery mechanism within the lumen and configured to apply fluid to (1) at least partially fragment the thrombus and (2) provide an optical path for the imaging element, and an aspiration mechanism fluidly coupled to the lumen and configured to aspirate the fragmented thrombus.
