Neurostimulator Titration Interface for Remote VNS Schedule Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The standard titration process for vagus nerve stimulation (VNS) therapy is lengthy and inefficient, particularly for patients with time-sensitive conditions like chronic heart failure, as it requires frequent physician visits and can lead to prolonged periods without receiving full therapeutic intensity, risking condition degradation.
Innovation Solution
A management device and method that allows for real-time data exchange with an implanted neurostimulator, displaying a user interface for titration parameter adjustment, enabling automated titration schedule determination and execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the standard titration process is used for VNS therapy, then patient safety and tolerance are maintained through gradual intensity increases, but the titration process becomes excessively lengthy and inefficient
Solution Approach 1:
The system pre-calculates and pre-programmes titration schedules and intensity increments before patient treatment begins. The management device stores predetermined titration protocols that can be automatically executed, eliminating the need for real-time physician calculations and visits during the titration process.
Solution Approach 2:
The management device autonomously manages the titration process by automatically adjusting stimulation intensity parameters based on pre-programmed schedules. The system self-regulates the titration process without requiring continuous physician intervention, allowing the device to independently progress through intensity levels according to the predetermined protocol.
2Reliability
If frequent physician visits are required for titration adjustments, then titration can be monitored and adjusted based on patient response, but patient productivity and convenience are reduced
Solution Approach 1:
The management device performs self-monitoring and self-adjustment of titration parameters based on pre-programmed protocols. The device automatically tracks patient response data and executes intensity adjustments without requiring physician presence, thereby maintaining monitoring reliability while significantly improving patient convenience.
Solution Approach 2:
The system continuously monitors patient response data and uses this feedback to validate the titration progression. The management device receives patient response information, compares it against predetermined criteria, and automatically adjusts or pauses the titration schedule accordingly, maintaining clinical reliability through continuous feedback loops.
3Object-affected harmful factors
If the titration process is extended to allow patient adaptation to each intensity level, then patient comfort and tolerance are improved, but the time to reach full therapeutic intensity is prolonged
Solution Approach 1:
The management device pre-establishes the complete titration schedule with predetermined intensity increments and timing intervals before treatment begins. This pre-planned schedule optimizes the balance between patient adaptation time and time to therapeutic intensity, ensuring that intensity increases follow scientifically validated intervals that minimize discomfort while accelerating the path to full therapy.
Solution Approach 2:
The system dynamically adjusts the titration schedule based on real-time patient response data and physiological parameters. The management device can modify intensity increment rates, timing intervals, and progression speed according to actual patient tolerance and therapeutic response, optimizing the balance between comfort and time efficiency for each individual patient.

AI summary
A method of managing titration using a management device for a patient implanted with a neurostimulator is provided. The method comprises: receiving, from the neurostimulator, a current titration schedule of a titration being provided to the patient by the neurostimulator; displaying a user interface on a display of the management device, the user interface including an indication of at least a portion of the current titration schedule, the user interface including one or more selectable options for modifying the titration; receiving a selection of the one or more selectable options via the user interface; generating a modified titration schedule of the titration based on the selection; and transmitting the modified titration schedule to the neurostimulator.
