Solution Overview

Problem

Current treatments for conditions like overactive bladder and other localized malfunctions in the body fail to specifically address local anatomical abnormalities, often requiring systemic approaches that can lead to overtreatment and side effects such as urinary retention.

Innovation Solution

A device with a plurality of electrodes that measures electrical activity and applies pacing stimuli to identify treatment sites, allowing for targeted therapies like radio frequency energy, ultrasound, or Botox injections to specific areas based on electrical activity patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current systemic treatments (drugs, nerve stimulation, Botox injections) are applied to treat the entire bladder, then the treatment covers all potential abnormal areas, but it leads to overtreatment of healthy areas and causes side effects such as urinary retention

Engineering Contradiction:
Improvetreatment efficacyVSAvoidside effects and overtreatment
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention divides the bladder treatment into multiple discrete electrode sites that can be independently activated. The system segments the treatment approach by identifying specific abnormal detrusor muscle areas through electrical activity measurement and applying therapy only to those segmented locations rather than treating the entire bladder, thereby avoiding overtreatment of healthy areas while maintaining treatment efficacy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention implements local quality by measuring electrical activity at multiple discrete electrode sites around the bladder and applying treatment selectively to sites showing abnormal activity patterns. This allows the treatment to have different properties at different locations - targeted therapy at abnormal sites versus no therapy at normal sites - thereby resolving the contradiction between comprehensive coverage and avoiding side effects.

Inventive Principle:
Principle #3Local quality

2Duration of action of stationary object

If Botox injections are repeated to maintain treatment effect, then the treatment effect is sustained over time, but it increases the risk of urinary retention and requires self-catheterization

Engineering Contradiction:
Improvetreatment durationVSAvoidurinary retention
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The invention employs feedback by continuously or periodically measuring electrical activity at electrode sites and using this information to guide treatment decisions. The system monitors the detrusor muscle electrical activity and adjusts therapy delivery based on real-time or near-real-time measurements, allowing sustained treatment effect while avoiding excessive treatment that would cause urinary retention. The feedback loop enables the system to stop treatment when abnormal activity resolves, preventing the need for repeated invasive injections.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If electrodes are used to measure electrical activity and identify specific treatment sites, then the treatment can be precisely targeted to abnormal areas, but the device complexity increases compared to systemic treatments

Engineering Contradiction:
Improvetreatment site identification accuracyVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The invention applies universality by designing electrodes that serve multiple functions: they act as both sensing elements for measuring electrical activity and as therapy delivery elements for applying treatment. This multi-functionality reduces device complexity compared to systems that would require separate sensing and treatment components, while still achieving precise treatment site identification through electrical activity measurement.

Inventive Principle:
Principle #6Universality (Multi-functionality)
