IMPLANTIERBARE MEDIZINISCHE VORRICHTUNG WIE EIN HERZSCHRITTMACHER MIT EINER EINRICHTUNG ZUR FESTSTELLUNG DER PRÄSENZ UND DES TYPES EINER ANGEORDNETEN SONDE

摘要

The device has a charge pumping circuit (24) to produce stimulated monopolar or bipolar pulses with or without disconnection of a link (S1,S2) to a reference potential. A discriminator (28) analyzes pulse width of a signal produced by varying the potential, and delivers an indication representing presence or absence of a probe. A control unit selectively modifies an operation parameter of the device based on the indication.
