Solution Approach 1:

The system incorporates automatic mode detection and selection based on the connected device type. The device detector automatically identifies whether the connected device requires ablation, pacing, or sensing mode, and the controller configures the appropriate parameters without manual intervention. This self-service approach reduces operational complexity while maintaining full functional versatility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control system dynamically adapts its behavior based on the detected device type and operational requirements. The controller modifies signal routing, parameter settings, and interface responses in real-time according to the active mode, allowing seamless transitions between ablation, pacing, and sensing functions while presenting a consistent simplified interface to the user.

Inventive Principle:

Solution Approach 1:

The control system is segmented into distinct functional modules: a device detector module that identifies connected devices, a controller module that manages signal routing and mode selection, and an interface module that handles user inputs. This segmentation allows each module to perform its specific function independently, simplifying the overall design while maintaining unified control capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces complex mechanical switching and manual configuration mechanisms with an electronic microprocessor-based control system. The microprocessor automatically detects device types, selects appropriate operational modes, and routes signals through software-controlled pathways, eliminating the need for physical switches and manual settings while reducing operational complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A matrix router with frequency switching is provided having an energy source electrically connected to a plurality of interface ports. A switching device is provided between the energy source and the plurality of switches. One of the plurality of interface ports includes a paired electrode interface port for the connection of a paired electrode device thereto. The paired electrode device has a first pair of opposed electrodes and a second pair of opposed electrodes for clamping on tissue. When the paired electrode device is operably connected to the paired electrode interface port and actuated, the switching device alternates energy such as bipolar RF from the first pair of opposed electrodes to the second pair of opposed electrodes.
