US 2026/0165718 A1 · THROMBUS REMOVAL SYSTEMS AND METHODS FOR BLOOD RETURN AND RECONSTITUTING REMOVED BLOOD CLOTS

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 a fluid delivery mechanism coupled with a fluid lumen and configured to apply fluid to at least partially fragment the thrombus.

Claims14

Dependent claims

A thrombus removal system, comprising:

an elongate shaft;
an aspiration lumen extending along the elongate shaft;
a vacuum source fluidly coupled to the aspiration lumen;
a thrombus filter disposed along the aspiration lumen;
and
a blood collection cannister disposed proximally from the thrombus filter along the aspiration lumen, the blood collection cannister including a moveable separator that divides the blood collection cannister into first and second chambers, wherein operation of the vacuum source causes clot removed from the patient to collect on the thrombus filter and blood removed from the patient to collect in the first chamber.
