Compartmentalized Cochlear Implant Fitting Software Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing aids are ineffective for individuals with sensorineural hearing loss, as they cannot bypass damaged or absent cochlear hair cells, leading to inadequate sound perception, necessitating the development of stimulating medical devices like cochlear implants that deliver electrical stimulation directly to the auditory nerve.
Innovation Solution
A compartmentalized fitting system that segregates the fitting procedure into clinician-driven setup, recipient-driven parameter determination, and clinician-approved parameter loading, allowing for personalized determination and approval of stimulation level parameters for cochlear implants, ensuring optimal device performance tailored to individual sound perceptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional clinician-driven fitting procedure is used for cochlear implants, then the clinician can control all parameter adjustments, but the process is time-consuming and less efficient
Solution Approach 1:
The patent segments the fitting procedure into distinct phases: a clinician-driven setup phase where initial parameters are configured, and a recipient-driven measurement phase where the recipient independently completes psychophysical measurements. This segmentation allows the clinician to oversee multiple sessions concurrently while maintaining control over critical setup parameters, thereby improving productivity without sacrificing clinical oversight.
Solution Approach 2:
The patent enables recipients to independently perform psychophysical measurements and parameter determinations during the fitting process through an automated system interface. This self-service capability reduces the time clinicians need to spend on routine measurements while ensuring personalized parameter optimization, effectively resolving the contradiction between efficiency and personalization.
2Measurement precision
If a recipient-driven fitting session is implemented, then the recipient can provide direct feedback on stimulation perception, but the system complexity increases
Solution Approach 1:
The patent introduces an automated fitting system as an intermediary between the clinician and the recipient. This intermediary manages the complex psychophysical measurement protocols, presents stimulation parameters, captures recipient feedback, and calculates optimized parameters automatically. By offloading the computational and procedural complexity to the intermediary system, the patent achieves high measurement precision without burdening the clinician or overwhelming the user interface.
3Reliability
If clinician approval is required for parameter changes, then safety and control are maintained, but the process becomes more cumbersome
Solution Approach 1:
The patent implements preliminary clinician approval for setup parameters before the recipient-driven measurement phase begins. Once approved, the system automatically applies these parameters throughout the fitting session without requiring repeated clinician interventions. This preliminary action approach maintains reliability and control while significantly simplifying the operational flow during the actual fitting process.
Data Source
AI summary
A compartmentalized fitting system that may be used by a recipient to determine device parameters, such as threshold and/or maximum comfort levels, for a stimulating medical device is provided. The compartmentalized fitting system segregates the fitting procedure into separate sessions. For example, in an embodiment, the fitting system provides a clinician driven setup session whereby a clinician may specify parameters that are to be used in fitting the medical device. After which, the fitting system may enter a recipient driven fitting session that is used to determine one or device parameters for the stimulating medical device. Once determined, the fitting system passes control to a clinician driven approval session whereby the clinician can approve the determined set of device parameters; and, if approved store the determined device parameters. This storage may comprise loading the determined device parameters onto the stimulating medical device for subsequent use by the device.
