Heart Valve Delivery Stabilizer for Precise Catheter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivering and securing replacement heart valves through minimally invasive procedures poses challenges due to the need for precise control over the delivery system's location and deployment, especially in tortuous vasculature, and ensuring atraumatic attachment to intralumenal tissue.
Innovation Solution
A stabilizer system with an elongated main body, angled surfaces, and adjustable clamps is used to securely hold and control the delivery system, allowing for precise motorized manipulation and atraumatic attachment to the base, facilitating controlled deployment of prostheses like replacement heart valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a delivery system is used to deliver replacement heart valves through minimally invasive procedures, then patient trauma is reduced, but control over the delivery system's location and deployment becomes more difficult
Solution Approach 1:
The stabilizer acts as an intermediary device between the operator and the delivery system. It provides a stable mounting platform with clamps and positioning mechanisms that enable precise control of the delivery system's location and deployment while maintaining the benefits of minimally invasive access.
Solution Approach 2:
The delivery system is divided into separable components including the stabilizer, clamps, and delivery catheter. This segmentation allows the stabilizer to be independently configured and adjusted to provide optimal control for each specific procedure while maintaining minimally invasive benefits.
2Adaptability or versatility
If the delivery system is made more flexible to navigate tortuous vasculature, then access to heart valves is improved, but stability and precision of deployment are reduced
Solution Approach 1:
The stabilizer serves as a stable intermediary platform that compensates for the flexibility of the delivery system. While the delivery catheter remains flexible to navigate tortuous vasculature, the stabilizer provides a rigid mounting base with precise positioning mechanisms to ensure stable and accurate deployment.
Solution Approach 2:
The stabilizer incorporates adjustable and movable components including sliding clamps and positioning mechanisms that can be dynamically adjusted during the procedure. This allows the system to adapt to different delivery system configurations while maintaining stability throughout the deployment process.
3Measurement precision
If the stabilizer system includes multiple adjustable components and clamps, then control precision is improved, but device complexity increases
Solution Approach 1:
The stabilizer is designed as a universal platform with multi-functional clamps and positioning mechanisms that can accommodate different delivery system configurations. This reduces the need for multiple specialized components while maintaining high control precision through standardized adjustable elements.
Solution Approach 2:
Multiple control functions are merged into integrated components of the stabilizer. The clamps combine securing, positioning, and adjustment functions in single elements, reducing the total number of separate components while maintaining comprehensive control capability.

AI summary
Disclosed herein are embodiments of methods of using stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.
