Solution Overview

Problem

Endoscopic examination and treatment of body lumens and cavities are hindered by complex anatomical configurations, soft tissue consistency, and tethering, leading to difficulties in visualization and access, especially in areas like the intestine where spasming and contraction complicate procedures.

Innovation Solution

A novel apparatus comprising a sleeve with aft and fore balloons and hollow push tubes, which stabilizes and expands the side wall of body lumens, allowing better visualization and access by inflating the balloons to create a stable therapeutic zone for endoscopic procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional flexible endoscopes are used to examine body lumens, then the endoscope can navigate through the lumen, but the side wall tissue cannot be fully visualized or accessed due to anatomical configuration, tissue consistency, and tethering

Engineering Contradiction:
Improveendoscopic examination capabilityVSAvoidvisualization of side wall tissue
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces an intermediary device (the apparatus with balloons and push tubes) that acts as a mediator between the endoscope and the side wall tissue. The balloons inflate to create a stable therapeutic zone, and the push tubes transmit forces to manipulate the tissue, enabling the endoscope to visualize and treat areas that would otherwise be inaccessible due to anatomical constraints

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The apparatus changes the physical parameters of the examination environment by inflating balloons to alter the configuration and stability of the body lumen. This creates a controlled therapeutic zone with improved visualization and access, transforming the dynamic, moving tissue into a stable field for endoscopic examination

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the body lumen is allowed to move and spasm naturally, then physiological function is maintained, but endoscopic visualization and instrument access are compromised

Engineering Contradiction:
Improvephysiological functionVSAvoidendoscopic visualization precision
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The apparatus performs preliminary action by inflating the balloons to stabilize the body lumen before endoscopic examination begins. This pre-stabilization creates a controlled therapeutic zone that prevents spasm and movement during the procedure, ensuring both physiological function is maintained and visualization precision is achieved

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus dynamically adjusts the stabilization of the body lumen by controlling balloon inflation and deflation. The system can transition between allowing natural movement and providing stable visualization as needed, adapting to the physiological requirements while enabling precise endoscopic examination

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If the endoscope is advanced through the body lumen, then examination coverage is increased, but the endoscope may grip and suddenly release the tissue, causing rapid movement past significant lengths

Engineering Contradiction:
Improveexamination coverage areaVSAvoidaccurate examination positioning
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The push tubes serve as intermediaries between the operator and the endoscope, providing continuous control and feedback. This intermediary mechanism prevents sudden gripping and releasing by allowing smooth, controlled advancement and maintaining precise positioning throughout the examination coverage area

Inventive Principle:
Principle #24Intermediary (Mediator)

4Loss of information

If balloons are inflated to stabilize the body lumen, then visualization and access are improved, but device complexity increases

Engineering Contradiction:
Improveside wall tissue visualizationVSAvoidapparatus structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The apparatus merges multiple functions into a single integrated device: the balloons for stabilization, the push tubes for tissue manipulation, and the connection to the endoscope for examination. This combining of functions reduces the need for separate devices and procedures, making the complex apparatus manageable and effective

Inventive Principle:
Principle #5Merging (Combining)
