Light-Emitting Brain Implant State Detection Through the Eye
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to determine the operating state of intracranial light-emitting implants without disassembly, as issues like defective light sources or broken optical fibers can occur post-implantation, making it difficult to assess functionality.
Innovation Solution
A non-invasive diagnosing device using a receiver to detect light signals through the eye, comparing measured light signals with reference data to determine the implant's functional state, employing components like photodiodes or cameras, and optionally a point light source to maintain gaze fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant is left implanted without removal for inspection, then the patient continues to receive treatment, but the operating state cannot be determined
Solution Approach 1:
The patent uses the patient's own eye as an intermediary medium to transmit light from the implanted source to an external detector. This allows indirect observation of the implant's operating state without physical access to the implant itself, resolving the contradiction between maintaining continuous treatment and enabling functional assessment.
Solution Approach 2:
The patent replaces the mechanical approach of surgical removal and direct inspection with an optical detection system. Light emitted by the implant travels through biological tissue and is detected externally, substituting invasive mechanical access with non-invasive optical measurement.
2Power
If the light source is made more powerful to ensure delivery, then treatment effectiveness improves, but detection of defects becomes more difficult
Solution Approach 1:
The patent establishes a feedback loop where light emitted by the implant is detected through the eye, and the detected signal provides information about the implant's operating state. This feedback mechanism allows assessment of whether the light source is functioning correctly, regardless of its power level, by measuring the actual light transmission through the optical path.
