AI Technical Summary
Technical Problem
Current thrombectomy devices struggle with navigating tortuous vascular anatomy, effectively removing thrombotic material, and providing accurate real-time feedback during procedures, leading to inefficiencies and potential over-aspiration of blood.
Method used
A steerable thrombectomy catheter with multiple fluid apertures for fractionating thrombi and a system for generating 3D models of the vasculature and clots, enabling precise navigation and real-time guidance using 2D and 3D imaging data.
Benefits of technology
Enhances the ability to accurately position the catheter relative to clots, reduces unnecessary blood aspiration, and improves treatment efficacy by providing fast and effective removal of various clot morphologies.

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 systems and methods discussed herein provide 3D models of the pulmonary vasculature, clots within the pulmonary vasculature, and / or of medical devices within the patient, for pre and peri-operative planning and navigation.
