Transcatheter Ventricular Reconstruction Anchors for Low-Trauma Reshaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for congestive heart failure, such as surgical interventions and implants, often require invasive procedures that impose significant trauma on patients and require complex surgical skills, and there is a need for less traumatic, less risky therapies that can effectively reduce ventricular volume and improve heart function.
Innovation Solution
A minimally invasive method and system using elongate shafts and anchors are deployed through the right atrium and epicardial approach to reshape the ventricle by bringing the septum and external wall into engagement, reducing ventricular volume by excluding scar tissue, with controlled deployment and anchoring mechanisms to avoid entanglement with heart structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical interventions and implants are used to treat congestive heart failure, then ventricular volume can be reduced and heart function improved, but patient trauma and procedural complexity increase significantly
Solution Approach 1:
The patent replaces traditional surgical mechanical systems with a catheter-based delivery system that uses a guidewire and delivery catheter to implant anchors and tensioning members percutaneously, eliminating the need for open surgical incisions and reducing patient trauma while achieving ventricular reconstruction
Solution Approach 2:
The patent introduces a delivery catheter as an intermediary device that facilitates the percutaneous delivery of anchors and tensioning members through the venous system to the ventricle, enabling minimally invasive access and reducing direct surgical trauma to cardiac tissues
2Shape
If traditional surgical methods are used, then ventricular reshaping can be achieved, but procedural complexity and surgical skill requirements increase
Solution Approach 1:
The patent replaces complex surgical procedures with a simplified catheter-based system that delivers pre-formed anchors and tensioning members through a delivery catheter, reducing procedural complexity and eliminating the need for specialized surgical skills while achieving precise ventricular reshaping
Solution Approach 2:
The patent divides the ventricular reconstruction system into separate modular components (anchors, tensioning members, delivery catheter) that can be independently delivered and assembled within the ventricle, simplifying the overall procedure and reducing surgical complexity

AI summary
Embodiments described herein include devices, systems, and methods for reducing the distance between two locations in tissue. In one embodiment, an anchor may reside within the right ventricle in engagement with the septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along a surface of the heart. Perforating the exterior wall and the septum from an epicardial approach can provide control over the reshaping of the ventricular chamber. Guiding deployment of the implant from along the epicardial access path and another access path into and through the right ventricle provides control over the movement of the anchor within the ventricle. The joined epicardial pathway and right atrial pathway allows the tension member to be advanced into the heart through the right atrium and pulled into engagement along the epicardial access path.
