View Finder Interface for Neurostimulation Lead Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neurostimulation systems face challenges in displaying implantable leads and their surrounding anatomical regions in a legible manner, as standard user interfaces struggle to provide both a global view of the spinal column and detailed local views simultaneously, leading to potential misplacement of neurostimulation leads and ineffective pain therapy.
Innovation Solution
An external control device with a user interface that allows for input and display of a global anatomical region, such as a spinal column, along with a view finder that can be modified in position, size, and dimension to focus on specific portions, enabling precise localization and programming of neurostimulation leads within the anatomical region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a standard user interface displays the entire spinal column, then the global view is provided, but the detailed local views of neurostimulation leads become illegible
Solution Approach 1:
The display is segmented into a global view portion showing the entire spinal column and a local view portion showing detailed anatomy around neurostimulation leads. This segmentation allows simultaneous presentation of both broad context and detailed information without compromising either view's legibility.
Solution Approach 2:
The interface transitions from a single two-dimensional display to a multi-dimensional viewing experience by incorporating a view finder that can be positioned and sized independently. This allows the system to display the entire spinal column in one dimension while simultaneously providing zoomed-in local views in another dimension through the view finder mechanism.
2Loss of information
If the view finder size is increased to show more anatomical detail, then the local view becomes more comprehensive, but the global context is reduced
Solution Approach 1:
The display is segmented into a global view portion showing the entire spinal column and a local view portion showing detailed anatomy around neurostimulation leads. This segmentation allows simultaneous presentation of both broad context and detailed information without compromising either view's legibility.
Solution Approach 2:
The view finder is nested within the global display area, allowing the detailed local view to be contained within the context of the overall spinal column view. This nesting enables users to maintain awareness of global anatomy while examining local structures in detail.
3Measurement precision
If the view finder position is changed to focus on different anatomical regions, then the localization precision is improved, but the navigation complexity increases
Solution Approach 1:
The system provides visual feedback by displaying the view finder's current position and size on the spinal column representation. This feedback mechanism helps users understand where they are in the anatomical structure and what region is currently being viewed, making navigation more intuitive and reducing complexity.
Solution Approach 2:
The view finder is made dynamically adjustable in both position and size, allowing users to interactively navigate to different anatomical regions and zoom levels. This dynamic capability enables precise localization while maintaining ease of operation through intuitive user interaction.

AI summary
An external control device for use with a medical component implanted within a patient. The device comprises a user interface configured for receiving user input, displaying a first graphical representation of the medical component in the context of a global graphical representation of an anatomical region of the patient, displaying a view finder defining a portion of the global graphical representation, and displaying a second graphical representation of the medical component in the context of a local graphical representation of the portion of the anatomical region portion. The external control device further comprises control circuitry configured for, in response to the input from the user, modifying the displayed view finder to spatially define a different portion of the global graphical representation, such that the second graphical representation of the medical component is displayed in the context of a local graphical representation of the different portion of the anatomical region.
