Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with neurogenic bladder, often resulting from paralysis, face challenges in sensing urine levels and timing urination, leading to inefficient catheter use, increased risk of urinary tract infections, and urethral damage due to frequent catheterization and reliance on time schedules.
Innovation Solution
An implantable bladder management system featuring a wireless sensor and valve integrated into a catheter that measures urine volume and pressure, allowing for accurate timing of urination and reducing the need for frequent catheter replacements by enabling users to control fluid flow internally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermittent catheters are used frequently to empty the bladder, then the bladder can be emptied, but the risk of urinary tract infections and urethral damage increases
Solution Approach 1:
The patent employs sensors that continuously monitor bladder volume and provide feedback to both the user (via alerts when volume exceeds threshold) and the valve mechanism (to automatically open when volume reaches predetermined level). This feedback system enables timely bladder emptying without over-catheterization, reducing infection risk while maintaining effective bladder management.
Solution Approach 2:
The implanted valve device operates autonomously based on sensor input, automatically opening to drain urine when the bladder reaches a predetermined volume level. This self-service mechanism reduces the need for frequent manual catheterization by individuals with neurogenic bladder, thereby decreasing their exposure to infection and mechanical urethral trauma.
2Reliability
If a time schedule is used to determine catheterization timing, then bladder emptying can be ensured, but the efficiency decreases and the risk of urinary accidents increases
Solution Approach 1:
The system replaces fixed time-schedule catheterization with real-time feedback from volume sensors. The sensor continuously monitors actual bladder volume and triggers catheterization only when necessary (when volume exceeds threshold), allowing individuals to optimize their catheterization timing based on actual need rather than arbitrary time intervals, thereby improving efficiency while maintaining reliability.
Solution Approach 2:
The patent substitutes the mechanical/time-based catheterization schedule with an electronic sensor-based volume detection system. The sensor accurately measures bladder volume in real-time and provides objective data to guide catheterization timing, replacing the inefficient time-based approach with a precise, need-based system that improves both efficiency and reliability.
3Reliability
If multiple catheterizations are performed daily, then bladder management is maintained, but the comfort of the individual decreases
Solution Approach 1:
The volume sensor provides real-time feedback about actual bladder fullness, enabling individuals to catheterize only when truly necessary rather than following rigid time schedules. This allows optimization of catheterization frequency based on actual physiological need, reducing unnecessary procedures and improving comfort while maintaining effective bladder management.
Solution Approach 2:
The automated valve system provides self-service by automatically opening to drain urine when the bladder reaches a predetermined volume level, eliminating the need for frequent manual catheterization. This reduces the burden and discomfort associated with multiple daily catheterization procedures while maintaining effective bladder emptying.

AI summary
The disclosure relates generally to an extended use systems and devices for management of bladder function for people with urinary dysfunction, The system Includes a catheter which can include a sensor that can determine bladder condition and a valve that can control fluid flow. The catheter can be placed Inside the bladder using devices that facilitate insertion and extraction. The placement of the catheter can be done by a trained individual such as a patient, as well as a clinician, a nurse, or a caretaker, Once placed Inside the bladder, the catheter can be fully-internal, meaning no portion of the catheter is visible from outside of the patients body.
