Implantable Eye Pressure Feedback Control for Glaucoma Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glaucoma treatments, particularly drainage implants with fixed drain cross sections or externally influenced valves, fail to automatically adjust to variations in internal eye pressure, requiring manual intervention and are difficult to use.
Innovation Solution
Implantable drainage systems with integrated sensors and valves, combined with drug delivery systems, enable automated regulation of internal eye pressure through electromechanical mechanisms and telemetric monitoring, allowing for rapid and personalized adjustments based on real-time data processing and wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If drainage implants with fixed drain cross section or externally influenced valves are used, then the device structure is simple, but the system cannot automatically react to variations in internal eye pressure and requires manual intervention
Solution Approach 1:
The patent implements a closed-loop feedback system where an internal eye pressure sensor continuously monitors the pressure and transmits data to a control unit, which automatically adjusts the valve opening cross-section or drug delivery rate in response to pressure variations, eliminating the need for manual intervention
Solution Approach 2:
The system enables self-regulation by integrating all necessary components (sensor, control unit, actuator) within the implant itself, allowing the device to automatically adjust its own operation based on real-time pressure measurements without requiring external manual control
2Speed
If manual intervention is required for valve adjustment, then the device structure is simpler, but the system reacts too slowly to variations in internal eye pressure
Solution Approach 1:
The real-time feedback mechanism allows the system to detect pressure changes immediately and automatically trigger the appropriate response through the control unit and actuator, achieving rapid response without requiring manual intervention
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electromechanical or electromagnetic actuation system controlled by a microprocessor, enabling rapid and precise adjustment of the valve opening cross-section in response to pressure changes
3Reliability
If automated feedback-controlled regulation is implemented, then the response to pressure variations is rapid, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (pressure sensing, data processing, valve control, and drug delivery) into a single integrated implantable system, reducing the number of separate components and simplifying the overall device architecture while maintaining automated regulation capability
Solution Approach 2:
The control unit serves multiple functions: it processes data from the pressure sensor, determines the appropriate therapeutic response, controls the valve actuator, and manages drug delivery timing and dosage, thereby reducing the need for separate dedicated components for each function

AI summary
The invention relates to an arrangement and a software-based application for modifying an internal eye pressure in vivo, having modulating means for modifying the internal eye pressure and sensor means for capturing the internal eye pressure in vivo, and enabling easily operated and quickly reacting changes to the internal eye pressure while avoiding the disadvantages of the prior art, proposing that the modulating means are implemented for modifying the internal eye pressure as a function of the internal eye pressure captured by the sensor means.
