Cardiac mapping and ablation systems

摘要

A cardiac diagnosis and treatment system comprises a support carrying at least two electrodes. A conductor is associated with the support for selectively directing electrical signals to and from each electrode. The conductor includes a first buss for delivering power from an external power source, a second buss for transmitting electrode signals to an external signal processor, and a third buss for receiving control signals from an external signal source to multiplex the electrode signals from the electrodes through the second buss. A conduction line conducts power, control signals, and electrode signals from the external sources to the conductor.
