Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures require separate catheters for electro-anatomical mapping and ablation, prolonging the procedure, increasing risk, and costing more due to the need for two different devices.
Innovation Solution
An expandable basket catheter with integrated ablation electrodes and electro-anatomical sensing electrodes, including thermocouples, that can be expanded and collapsed for both sensing ECG signals and applying ablation signals, reducing the need for multiple catheters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate catheters are used for electro-anatomical mapping and ablation, then each function can be performed with specialized devices, but the procedure time increases and the risk to the patient increases
Solution Approach 1:
The patent combines electro-anatomical mapping electrodes and ablation electrodes into a single integrated basket catheter. The catheter includes multiple splines with both sensing electrodes for mapping and ablation electrodes for tissue ablation, allowing both functions to be performed with one device rather than requiring separate catheters, thereby reducing procedure time and patient risk
Solution Approach 2:
The basket catheter is designed as a multi-functional device that can perform both electro-anatomical mapping and ablation procedures. The catheter includes electro-anatomical sensing electrodes for detecting electrical signals and ablation electrodes for delivering ablation energy, enabling a single device to replace multiple specialized catheters

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integrated catheter allows for simultaneous electro-anatomical mapping and ablation, shortening procedure time, reducing risks, and lowering costs by using a single device for both functions.
Implementation Method 1
The systems may be configured to access tortuous anatomy of or adjacent hepatic vasculature. The systems may be configured to target nerves surrounding (e.g., within adventitia of or within perivascular space of) an artery or other blood vessel, such as the common hepatic artery.
Implementation Method 2
The present disclosure relates generally to medical devices, and particularly to production methods and expandable catheters having ablation electrodes and electro-anatomical sensing electrodes.
