Solution Overview
Problem
Current catheter ablation systems for treating cardiac arrhythmias, such as atrial fibrillation, face challenges in accurately and efficiently positioning ablation devices within the left atrium due to stability and positioning constraints, leading to prolonged procedural times and complexities in creating desired lesion patterns.
Innovation Solution
A delivery system comprising a deployable guide system and positioning element that defines a stable operative path within the body, allowing for the accurate and efficient deployment of functional devices, such as ablation devices, without the need for constant redeployment, using a guide system with a longitudinal axis and a positioning element that cooperates to position the device along the defined path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If catheter ablation systems use distal end electrodes guided to multiple positions for creating lesion sets, then the ability to create desired lesion patterns is achieved, but the procedural time increases tremendously due to positioning problems and the need for constant redeployment
Solution Approach 1:
The guide system is deployed in advance to define the operative path and stable platform before the ablation procedure begins. This preliminary positioning eliminates the need for constant redeployment during the procedure, as the guide system remains in place to support multiple ablation deliveries along the predetermined path.
Solution Approach 2:
The guide system acts as an intermediary between the operator and the ablation catheter. It provides a stable platform and defined operative path that facilitates accurate positioning of the ablation device without requiring the operator to manually reposition the catheter multiple times, thereby reducing procedural time while maintaining positioning accuracy.
2Measurement precision
If catheter systems require stable platform for accurate positioning of ablating device, then positioning precision is improved, but the device complexity and operational constraints increase
Solution Approach 1:
The system is divided into distinct functional components: the guide system that defines the operative path and provides the stable platform, and the ablation catheter that delivers the therapeutic function. This segmentation allows the guide system to be optimized for stability and positioning while the ablation catheter focuses on the ablation function, reducing overall system complexity.
Solution Approach 2:
The guide system serves multiple functions: it defines the operative path, provides a stable platform for positioning, and enables accurate delivery of the ablation catheter to multiple positions along the path. This multi-functionality reduces the need for additional specialized devices, thereby reducing system complexity while maintaining positioning precision.
3Ease of manufacture
If catheter ablation requires remote and percutaneous manipulation of ablating device to desired points in left atrium, then minimally invasive access is achieved, but the ease of operation decreases due to positioning constraints
Solution Approach 1:
The guide system serves as an intermediary that facilitates the remote and percutaneous manipulation of the ablation catheter. By providing a defined operative path and stable platform, it simplifies the operator's task of navigating the catheter to desired positions within the left atrium, making the procedure easier to perform while maintaining minimally invasive access.
