Tissue Grasper Assembly for Secure Wall Apposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Challenges exist in moving and anchoring tissue walls to form an anastomosis or repair tissue effectively, with existing tools lacking in efficiency and risk of leakage.
Innovation Solution
A tissue-manipulating device with a shaft, tissue grasper assembly, and controller, featuring movable grasper arms that can transition between closed and open configurations, allowing for tissue engagement and approximation, optionally with a sharpened element for puncturing, and a locking mechanism for holding tissues in apposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing tissue manipulation tools are used to move and anchor tissue walls, then the procedure can be completed, but the process is time-consuming and carries a risk of leakage
Solution Approach 1:
The patent replaces traditional mechanical suturing systems with a magnetic field-based tissue approximation system. Magnets are positioned on opposite sides of the tissue wall, creating magnetic attraction forces that pull tissue edges together without mechanical penetration or stitching, thereby reducing procedural time and eliminating leakage risks associated with traditional mechanical methods
Solution Approach 2:
The patent utilizes magnetic field strength as a controllable parameter to achieve tissue approximation. By adjusting the strength and configuration of magnetic fields, the system can securely hold tissue walls in apposition without mechanical contact, improving reliability while maintaining procedural efficiency
2Productivity
If traditional surgical tools are used for tissue approximation, then the procedure is well-established, but the tools lack efficiency and require complex manual manipulation
Solution Approach 1:
The patent replaces manual mechanical manipulation with an automated magnetic field system. The magnetic approximation device can be controlled to precisely position and hold tissue walls without requiring complex manual dexterity, thereby improving procedural efficiency while simplifying the operator's task
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the operator and the tissue. Instead of directly manipulating tissue with hands and traditional tools, the operator controls magnetic fields that indirectly manipulate the tissue, improving ease of operation and procedural efficiency

AI summary
A tissue-manipulating system including a tissue-manipulating device having a tissue grasper assembly with at least one grasper arm movably coupled to a shaft to move between a closed configuration and an open configuration. The at least one grasper arm may be pivotably coupled to the shaft, such as via a collar. A tissue-manipulating device controller is coupled to the tissue grasper assembly to move the at least one grasper arm between the closed and open configurations. The tissue grasper assembly is positionable to move a distal tissue wall closer to a proximal tissue wall. The tissue grasper assembly may be deployable (such as by separating from the shaft) to remain in place holding the distal tissue wall and proximal tissue wall in apposition.
