Posture-Responsive Therapy Adjustment for Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices that deliver therapy, such as electrical stimulation or therapeutic agents, face challenges in maintaining therapeutic efficacy as patients change posture states, leading to inconsistent treatment outcomes due to changes in electrode positioning and symptom levels.
Innovation Solution
Incorporating a posture state module that detects patient posture and adjusts therapy parameters, such as amplitude, pulse rate, or selects different therapy programs, to maintain effective treatment across various postures, with options for patient or clinician interaction through external programmers to manage and adjust therapy settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If therapy parameters are fixed according to a predetermined program, then the device operation is simple and reliable, but the therapeutic efficacy becomes inconsistent when patient posture changes
Solution Approach 1:
The patent implements dynamic therapy delivery by detecting patient posture states and automatically adjusting therapy parameters in real-time. The medical device transitions from static, predetermined therapy programs to dynamic, posture-responsive therapy delivery, ensuring consistent therapeutic efficacy across varying patient positions through continuous adaptation of stimulation parameters based on detected posture changes
Solution Approach 2:
The patent employs feedback mechanisms where the medical device continuously monitors patient posture states through sensors and uses this information to automatically adjust therapy parameters. The system closes the control loop by detecting posture changes and responding with appropriate therapy modifications, eliminating the need for fixed predetermined programs and maintaining consistent therapeutic效果 despite posture variations
2Reliability
If the medical device automatically adjusts therapy parameters in response to posture changes, then therapeutic efficacy is maintained, but the device complexity and energy consumption increase
Solution Approach 1:
The patent implements periodic posture detection and therapy adjustment cycles rather than continuous monitoring. The medical device detects posture states at predetermined intervals or upon detecting significant posture transitions, adjusting therapy parameters periodically based on these detections. This approach maintains therapeutic efficacy while reducing energy consumption compared to continuous real-time monitoring and adjustment
3Adaptability or versatility
If the patient manually adjusts therapy parameters, then the therapy can be customized to patient needs, but the patient burden and time consumption increase
Solution Approach 1:
The patent implements self-service therapy adjustment where the medical device autonomously detects patient posture states and automatically modifies therapy parameters without requiring patient intervention. The system performs the customization function itself by responding to detected posture changes, eliminating the need for patients to manually adjust settings while maintaining personalized therapy adaptation to their needs

AI summary
In general, the disclosure relates to the delivery of therapy according to a detected posture state of a patient. The disclosure contemplates a variety of techniques for managing therapy delivered to a patent. In one example, the disclosure relates to a technique including delivering therapy to a patient from a medical device, wherein the therapy is delivered to the patient according to a detected posture state of the patient; and automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior, wherein automatically adjusting at least one aspect of therapy comprises suspending at least one aspect of the therapy or decreasing a posture state detection frequency.
