Ultrasonic Device State Characterization Method, Apr 23
Summary
USPTO published patent application US20260108134A1 on April 23, 2026, covering a method for characterizing the state of an end effector of an ultrasonic device. The method involves a control circuit applying power to an ultrasonic transducer, measuring impedance values, and comparing them to stored reference values to classify and characterize the electromechanical ultrasonic system state, then adjusting power accordingly. The application was filed on August 5, 2025, under application number 19291303.
About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
The patent application discloses a method for characterizing the state of an electromechanical ultrasonic system using impedance measurement and power adjustment. A control circuit applies power to an ultrasonic transducer, measures its impedance value, compares it to stored reference impedance values, classifies the measurement, and characterizes the system state based on the classification. The power level applied to the ultrasonic transducer is then adjusted based on this characterization.
Medical device manufacturers developing ultrasonic surgical instruments and robotics companies designing automated surgical systems are affected by this publication. The method enables more precise energy delivery control through real-time impedance-based feedback, which could impact the design of next-generation ultrasonic surgical devices and smart medical robotics platforms.

Abstract
A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer; measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer; comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.
