Tissue Management Clamp for Vascular Anastomosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing tissue during vascular access procedures, such as hemodialysis, lack efficient and reliable systems for creating and maintaining anastomoses between vessels and access devices, leading to challenges in repeated access and potential complications.
Innovation Solution
The development of a tissue management system comprising a clamp assembly, dilation device, and anastomosis actuation device that allows for secure attachment of access devices to blood vessels, enabling repeated access while minimizing tissue damage and ensuring vessel patency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current tissue management methods are used during vascular access procedures, then the procedures can be performed, but the efficiency and reliability of creating and maintaining anastomoses is insufficient
Solution Approach 1:
The patent combines multiple functions (clamping, dilation, anastomosis creation and maintenance) into a single integrated tissue management system. The system includes a clamp assembly with compression elements, a dilation device with expandable elements, and an anastomosis actuation device that work together as a unified system, eliminating the need for separate devices and improving both reliability and efficiency.
Solution Approach 2:
The tissue management system is designed to perform multiple functions: it can clamp and compress tissue, dilate the access site, create anastomoses, and maintain them over time. The clamp assembly can be adjusted to different configurations, and the dilation device can be expanded to various sizes, providing universal applicability for different vascular access requirements.
2Adaptability or versatility
If repeated vascular access is attempted without a secure attachment system, then access can be obtained, but tissue trauma increases and vessel patency is compromised
Solution Approach 1:
The system performs preliminary actions by creating a secure anastomosis with the clamp assembly before repeated access is needed. The anastomosis is formed with proper tissue apposition and sealing, and the system maintains this connection over time, allowing for repeated access without causing additional tissue trauma. The preliminary secure attachment prevents the need for repeated punctures or surgical interventions.
Solution Approach 2:
The tissue management system acts as an intermediary between the vascular access device and the vessel wall. The clamp assembly with its compression elements provides a controlled interface that distributes forces evenly, while the dilation device creates a gradual expansion path, minimizing direct trauma to the tissue during insertion and access.
3Ease of operation
If a simple access method is used, then the procedure is easier to perform, but the system cannot maintain vessel patency or enable repeated access
Solution Approach 1:
The tissue management system is segmented into distinct functional modules: the clamp assembly with compression elements for securing tissue, the dilation device with expandable elements for creating access, and the anstomosis actuation device for forming connections. This segmentation allows each component to be optimized for its specific function while maintaining overall ease of operation through systematic deployment.

AI summary
Tissue management methods can include inserting a clamping device into a vessel and clamping a vessel wall via the clamping device. Tissue can be dilated about the clamping device and an anastomotic device provided to the vessel.
