CILAG Surgical Tissue Detection Patent (US12599379B2)
Summary
USPTO granted patent US12599379B2 to CILAG GMBH INTERNATIONAL on April 14, 2026. The patent covers devices, systems, and methods for detecting tissue and foreign objects during surgical operations using electrodes and impedance-based detection. The patent application was filed on February 26, 2024.
What changed
USPTO granted patent US12599379B2 to CILAG GMBB INTERNATIONAL covering surgical instruments with end effectors containing electrodes configured to detect media and foreign objects during surgical procedures. The patent discloses a control circuit and algorithm that determine impedance signals to detect and position detected media, generating alerts for operators.
Medical device manufacturers developing surgical instruments with tissue detection capabilities should review this patent for potential licensing needs or design-around considerations. The patent's 20 claims protect specific methods for impedance-based tissue detection in surgical jaws, which may impact competitive product development in the surgical device space.

Abstract
A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.
