Urethral Catheter Balloon Positioning for Trauma Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for urinary incontinence often cause pain, discomfort, and inconvenience due to their invasive nature and inability to reduce localized irritation to the urethra.
Innovation Solution
A non-bladder invasive urethral catheter system with a urethral balloon element that blocks urine flow until the user is ready to urinate, featuring interchangeable catheters with differently positioned balloon elements to reduce trauma and irritation, allowing for increased mobility and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a urethral catheter with a balloon element is used to block urine flow, then urinary incontinence is effectively managed, but localized irritation and trauma to the urethral walls occurs
Solution Approach 1:
The catheter system enables dynamic repositioning of the balloon element along the urethra. The flexible elongated body allows the balloon to be moved to different positions (proximal, middle, distal sections) to distribute trauma and find optimal locations that minimize irritation while maintaining effective urine flow blocking. This dynamic adaptability resolves the contradiction by allowing the system to maintain reliability while reducing harmful localized effects through positional adjustment.
Solution Approach 2:
The system changes the positional parameter of the balloon element along the urethral length. By providing multiple catheters with balloons positioned at different locations (first section, second section, third section), the system can select and switch between different positional parameters to minimize localized trauma while maintaining the blocking function. This parameter variation allows the same basic device to reduce harmful effects without sacrificing effectiveness.
2Reliability
If traditional invasive catheter solutions are used, then urinary incontinence is managed, but user comfort and quality of life deteriorate due to pain and inconvenience
Solution Approach 1:
The catheter employs a flexible elongated body that can conform to the natural contours of the urethra without causing discomfort. This flexibility allows the device to be easily inserted and positioned while permitting normal urethral movement and user activities. The flexible construction resolves the contradiction by maintaining effective incontinence management through proper positioning while significantly improving user comfort and ease of operation.
Solution Approach 2:
The catheter system allows dynamic adjustment of the balloon position along the flexible body to optimize both effectiveness and comfort. By being able to reposition the balloon element, the system can achieve reliable urine flow blocking while minimizing irritation and discomfort, thereby improving overall user comfort and quality of life without sacrificing incontinence management effectiveness.
3Device complexity
If a single fixed-position catheter is used, then device simplicity is maintained, but adaptability to reduce trauma to different urethral areas is limited
Solution Approach 1:
The catheter system is segmented into multiple catheters, each with the balloon element positioned at a different location along the elongated body (first section, second section, third section). This segmentation allows the user to select the appropriate catheter based on which urethral area needs relief from trauma. The segmented approach resolves the contradiction by providing adaptability to reduce localized trauma through multiple specialized components, while each individual catheter remains relatively simple in structure.

AI summary
A non-bladder invasive urethral catheter system is provided as a system of apparatuses that provide a means relieving a user's urinary incontinence issues while reducing localized compression to the walls of their urethra. The non-bladder invasive urethral catheter system provides a more convenient and less intrusive means of enabling individuals suffering from urinary incontinence to live an ordinary life. The non-bladder invasive urethral catheter system provides the user with comfort and increased mobility and permits the user to maintain the indwelling catheter during urination. The apparatus blocks urine flow and leakage while installed within a user. The non-bladder invasive urethral catheter system utilizes several urethral catheters that are differentiated by the positioning of a urethral balloon element on the elongated body of the urethral catheter. Through the substitution of the differentiated urethral catheters, the user is able to reduce the trauma to a particular area of their urethra.
