Multi-Lumen Valve Repair Delivery System for Consistent Locking Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical methods for mitral valve repair lack consistency in locking forces, leading to irregular valve closure and potential blood flow issues due to uneven valve commissure shape, which can result in insufficient blood supply or reflux.
Innovation Solution
A delivery system with synchronized locking mechanisms for multiple nailing devices, utilizing a multi-lumen tube and adjustable sheath tube assembly to ensure consistent locking forces through real-time adjustment and precise control of wire lockers and nailing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple nailing devices are used for valve repair, then the repair effectiveness is improved, but the consistency of locking forces deteriorates
Solution Approach 1:
The patent combines multiple wire locker control devices into a single integrated control system. The first and second wire locker control devices are connected in series, allowing both wire lockers to be controlled by a single operator through coordinated manipulation of one control device, thereby ensuring consistent locking forces across multiple nailing devices.
Solution Approach 2:
The patent introduces a common control mechanism as an intermediary between the operator and multiple wire lockers. This intermediary control system transmits control signals uniformly to multiple wire lockers, ensuring that each locker applies consistent locking force to its respective nailing device, thus resolving the inconsistency problem.
2Productivity
If multiple delivery assemblies are used for simultaneous nailing, then the surgical efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent designs the wire locker control device with multi-functionality, enabling it to control multiple wire lockers simultaneously. This universal control mechanism can manage both the first and second wire lockers through a single device, reducing the need for separate control systems for each delivery assembly and thereby simplifying the overall system.
Solution Approach 2:
The patent segments the delivery system into modular components (first delivery assembly, second delivery assembly, wire locker control devices) that can be independently manufactured and assembled. This segmentation allows for standardized interfaces and control mechanisms, making the complex system more manageable and easier to operate despite its multiple functional components.
3Adaptability or versatility
If wire lockers are controlled separately, then the adaptability to different nailing positions is improved, but the locking force uniformity deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms in the wire locker control device that allow the operator to monitor and adjust the locking forces in real-time. The control system provides tactile or visual feedback on the force being applied by each wire locker, enabling the operator to maintain uniform locking forces while adapting to different nailing positions and anatomical variations.
