Medical Electrode Device with Movable Active Electrode
Summary
The USPTO issued Patent US12594117B2 to Boston Scientific Scimed, Inc. on April 7, 2026, covering a medical device featuring a shaft with a distal passive electrode containing a central opening and a movable active electrode. The active electrode can transition between an extended position (not contacting the passive electrode) and a retracted position (contacting the passive electrode). The patent contains 18 claims.
What changed
The USPTO granted Patent US12594117B2 to Boston Scientific Scimed, Inc. for a medical electrode device designed for diagnostic and surgical applications. The patent covers a passive electrode defining a central opening with an active electrode movably positioned within that opening. The active electrode is configured to move between extended and retracted positions to control contact with the passive electrode.
Medical device manufacturers developing similar electrode-based surgical or diagnostic tools should be aware of this patent to avoid potential infringement issues. The patent's broad claim structure covering movable electrodes between extended and retracted positions may affect product development strategies in the ablation and electrosurgery device space.
