Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing endoscopic closure methods are inadequate for large defects resulting from treatments like lesion removal or post-surgical repairs, lacking effective devices to securely close wounds.

Innovation Solution

A suture device with a suture translation assembly and an elongate tool guide that can transition between deployment and working configurations, allowing for precise suture placement and closure of large defects using an endoscope or similar delivery systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing endoscopic closure methods are used, then small defects can be closed, but large defects resulting from treatments like lesion removal or post-surgical repairs cannot be effectively closed

Engineering Contradiction:

Improveclosure capabilityVSAvoidclosure security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The suture device incorporates a translation assembly that can dynamically adjust the position of the suture needle relative to the endoscope, enabling the device to adapt to large defects while maintaining secure closure through controlled suture placement

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The closure device is divided into separate functional components including the endoscope, suture needle, and translation assembly, allowing each component to be optimized for its specific function while working together to close large defects securely

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If a suture translation assembly is added to enable precise suture placement, then closure precision is improved, but device complexity increases

Engineering Contradiction:

Improvesuture placement precisionVSAvoiddevice structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The translation assembly serves multiple functions including positioning the suture needle, guiding suture placement, and enabling precise control during closure, thereby improving precision without requiring multiple separate devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A suture device for use in combination with a delivery system including a lumen extending through the delivery system includes a needle usable to carry a suture, a distal shuttle configured to releasably secure the needle, a sleeve disposable over the distal shuttle, the distal shuttle movable relative to the sleeve between a locked position in which the needle is locked to the distal shuttle and an unlocked position in which the needle is releasable from the distal shuttle. The suture device includes a distal assembly including an elongate tool guide movable between a deployment configuration in which the elongate tool guide is substantially parallel with the distal assembly and a working configuration in which the elongate tool guide curves away from the distal assembly.
