Solution Overview

Problem

Existing medical devices lack the capability to efficiently deliver multiple accessory devices simultaneously during procedures, such as endoscopic submucosal dissection, due to limited luminal space and structural constraints.

Innovation Solution

The development of medical devices with multiple lumens and perforations allows for the simultaneous delivery and independent manipulation of accessory devices outside the scope, enabling over-the-scope delivery and uncoupling mechanisms through perforations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a medical device includes multiple lumens for delivering accessory devices, then the capability to deliver multiple accessory devices simultaneously is improved, but the device complexity increases

Engineering Contradiction:

Improvecapability to deliver multiple accessory devicesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a nested lumen structure where multiple lumens are positioned concentrically, with inner lumens containing accessory devices that can be delivered through outer lumens. This nesting arrangement allows multiple accessory devices to be delivered simultaneously through a single medical device while maintaining a relatively compact and manageable structure, thus resolving the contradiction between delivery capability and device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The medical device is segmented into multiple functional lumens, each capable of independently delivering different accessory devices. This segmentation allows the device to handle multiple tasks simultaneously through separate channels, improving versatility while organizing complexity into distinct, manageable segments rather than a monolithic structure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If accessory devices are delivered outside the scope, then procedural flexibility is improved, but the difficulty of delivering and positioning devices increases

Engineering Contradiction:

Improveprocedural flexibilityVSAvoidease of delivering and positioning devices

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces delivery catheters as intermediary devices that facilitate the delivery of accessory devices from the lumens to the target site outside the scope. These catheters act as mediators that simplify the delivery process by providing a controlled pathway and positioning mechanism, thus improving ease of operation while maintaining the flexibility of delivering devices outside the scope.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The delivery system is pre-configured with accessory devices loaded within the lumens before the procedure begins. This preliminary preparation allows for smooth, pre-planned delivery sequences during the procedure, reducing the complexity of real-time device manipulation and improving ease of operation while maintaining procedural flexibility.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If multiple accessory devices are used simultaneously, then procedural efficiency is improved, but the device structure becomes more complex

Engineering Contradiction:

Improveprocedural efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The medical device is designed with universal lumens that can accommodate and deliver different types of accessory devices interchangeably. This multi-functionality allows the same delivery system to handle various accessory devices simultaneously, improving procedural efficiency without requiring separate specialized delivery mechanisms for each device type, thus managing structural complexity effectively.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A medical device may comprise a first wall defining a first lumen. The first lumen may be configured to receive a shaft of a medical scope. Further, the medical device may include at least one second wall defining a second lumen. The at least one second lumen may be configured to receive an accessory device. The at least one second wall may include a perforation that may extend longitudinally along the at least one second wall.
