A method and system for programming spinal cord stimulators that allow healthcare professionals to select and adjust electrode sets, migrate stimulation parameters, and communicate these changes to an implantable pulse generator using a clinician programmer, enabling discrete amplitude and polarity changes to optimize therapeutic electrical stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional spinal cord stimulation programming methods are used, then the system can provide basic electrical stimulation, but the ability to precisely adjust electrode configurations and migrate stimulation parameters is limited
Solution Approach 1:
The programming system is segmented into distinct functional modules: electrode selection interface, parameter adjustment controls, migration functionality, and communication interface. This modular approach enables precise control over stimulation parameters while maintaining manageable system complexity through organized, separable components.
Solution Approach 2:
The system implements dynamic parameter adjustment capabilities that allow real-time modification of stimulation settings during programming sessions. The migration feature dynamically relocates stimulation parameters between electrode configurations based on patient feedback, enabling adaptive optimization without requiring complete reprogramming.
2Manufacturing precision
If discrete migration of stimulation parameters is implemented, then parameter adjustment precision is improved, but the time required for programming sessions increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring migration pathways and storing electrode configuration templates before actual programming sessions. Common parameter sets and electrode arrangements are prepared in advance, allowing rapid deployment and reducing the time required for detailed adjustment during patient programming sessions.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor patient response to stimulation parameters in real-time. This feedback drives the discrete migration process, automatically adjusting parameters based on measured outcomes and reducing the need for lengthy iterative manual adjustments by clinicians.

AI summary
An electronic programmer is used to program a pulse generator to generate electrical stimulation to be delivered to a patient via an implantable lead. The electronic programmer simultaneously displays, via an user interface, a first control mechanism and a second control mechanism that is separate and different from the first control mechanism. A first user input is received via the first control mechanism, and a second user input is received via the second control mechanism. In response to the received first user input and the second user input, the electronic programmer sends instructions to the pulse generator to cause a migration of the electrical stimulation from a first set of electrodes on the implantable lead to a second set of electrodes on the implantable lead. The first user input defines a stimulation amplitude change for the migration, and the second user input defines a direction for the migration.
