Synchronized Aspiration System with Catheter Sensors for Removal of Acute Blockages from Blood Vessels
Summary
USPTO granted Patent US12605499B2 to Neuravi Limited on April 21, 2026, covering a synchronized aspiration catheter system with integrated electrode pairs and pressure sensors for removing acute blood clots from patient vessels. The control console modulates aspiration vacuum pressure based on sensor inputs and optionally the patient's blood pressure waveform. The patent application was filed May 12, 2022, under application number 17743121, with 9 claims.
What changed
USPTO issued Patent US12605499B2 to Neuravi Limited, covering an aspiration catheter system with electrode pairs and pressure sensors positioned inside and outside the catheter lumen. The control console modulates vacuum pressure waveforms based on electrical and pressure inputs from the sensors, optionally incorporating patient blood pressure waveform patterns.
Healthcare providers and medical device manufacturers should note this patent for freedom-to-operate assessments in the clot retrieval and aspiration catheter space. The patent's claims cover both the sensor configuration and the control logic for modulating aspiration pressure.

Abstract
An aspiration catheter for assisting in the retrieval of a clot from a vessel of a patient including at least one electrode pair and a first pressure sensor positioned within an inner lumen of the aspiration catheter and a second and third pressure sensor positioned on an exterior surface of the aspiration catheter. The electrode pair and pressure sensors are in electrical communication with a control console. The control console is configured to modulate an aspiration vacuum pressure waveform pattern applied through the aspiration catheter based on electrical and pressure inputs from the one or more sensors, and optionally based on a blood pressure waveform pattern of the patient.
