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.
Claims21
A method, comprising:
- advancing a thrombectomy system into a pulmonary artery of a subject;
- periodically or continuously measuring a pulmonary artery pressure with the thrombectomy system;
- advancing a P-V catheter into a right ventricle of the subject;
- periodically or continuously measuring right ventricular pressure, right ventricular conductance, and/or a right ventricular admittance with the P-V catheter;
- initiating a thrombectomy procedure with the thrombectomy system;
- and
- determining a treatment progress or treatment completion state based on a correlation between the measured pulmonary artery pressure and/or the right ventricular pressure, right ventricular conductance, and/or a right ventricular admittance.

5 more elements
A thrombectomy system, comprising:
- an introducer sheath;
- a thrombectomy device adapted to be inserted into the introducer sheath to place the thrombectomy device within a pulmonary artery of a subject, the thrombectomy device including an aspiration lumen coupled to an aspiration source;
- a pressure sensor disposed on the introducer sheath and/or the thrombectomy device and configured to measure a pulmonary artery pressure of the subject;
- a P-V catheter adapted to be inserted into a right ventricle of the subject, the P-V catheter being configured to measure a right ventricular pressure, a right ventricular conductance, and/or a right ventricular admittance;
- one or more processors;
- and
- memory coupled to the one or more processors, the memory configured to store computer-program instructions, that, when executed by the one or more processors, implement a computer-implemented method, the computer-implemented method comprising:
- determining a treatment progress or treatment completion state based on a correlation between the measured pulmonary artery pressure and/or the right ventricular pressure, right ventricular conductance, and/or a right ventricular admittance.
