FILTER CIRCUIT FOR ELECTROPHYSIOLOGY SYSTEM

摘要

An ablation generator may include an input port for receiving a monitoring signal respective of tissue of the patient and an output port for providing the monitoring signal another device. A filtering circuit may be disposed between the input port and the output port, the filtering circuit configured to present a high impedance at one or more frequencies at or near which a mapping and navigation system associated with the ablation generator transmits a signal. The filtering circuit may additionally or alternatively be provided in a monitoring system or another component in an electrophysiology system.
