Dual-Component Tissue-Engaging Device for Insufflation Traction

Solution Overview

Problem

Existing medical procedures face challenges in maneuvering and lifting tissue during minimally invasive procedures due to limited space, leading to obstructed visibility and increased complexity, requiring separate tools and potentially larger delivery devices.

Innovation Solution

A tissue-engaging device with two differently shaped components allows grasping and anchoring of target and anchor tissues within a body lumen, using insufflation to apply traction by separating these sections, facilitating cutting and removal without additional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate medical tools are used to lift and manipulate tissue, then tissue manipulation capability is improved, but device complexity and procedure time increase

Engineering Contradiction:

Improvetissue manipulation capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple tissue manipulation functions (grasping, lifting, anchoring) into a single tissue engaging device with multiple components. The first component engages target tissue while the second component engages anchor tissue, allowing both functions to be performed by one device rather than requiring separate tools.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tissue engaging device is designed as a multi-functional instrument that can perform multiple operations: the first component grasps target tissue for manipulation, the second component anchors to provide traction, and the device can be used for both lifting and cutting operations within a single procedural context.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate medical tools are used to lift and manipulate tissue, then tissue manipulation capability is improved, but procedure time increases

Engineering Contradiction:

AI summary

A device, system, and method for engaging tissue and/or applying traction to tissue. A first component of a tissue-engaging device engages a first section of tissue while a second component of the tissue-engaging device engages a second section of tissue spaced apart from the first section of tissue. The first component may be configured to grasp target tissue at the first section, whereas the second component may be configured to simply engage, but not grasp, anchor tissue at the second section. Thus, the second component may grasp anchor tissue with the assistance of the second component, but may be readily removed from the anchor tissue without damaging the anchor tissue while the target tissue remains grasped by the second component.
