The EPO published Medtronic's patent application EP3701862A1 on March 25, 2026, covering multi-threshold sensing technology for extracardiovascular implantable cardioverter defibrillators (ICDs). The patent describes methods and systems for improved detection of cardiac electrical signals using variable sensing thresholds to enhance arrhythmia detection accuracy. Inventors include Jian Cao, Timothy Ebeling, Saul Greenhut, and others. The application claims priority to IPC classifications in A61B (diagnosis) and A61N (electrical therapy devices).

This patent publication does not impose compliance obligations on healthcare providers or medical device manufacturers. Competitors developing similar cardiac sensing technology should review the claims to assess potential freedom-to-operate implications. Medical device companies engaged in ICD development may wish to monitor this patent's progression through the examination process.
