Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple independent sources of information (positioning, physiological measurements, operational parameters) are provided separately during a medical procedure, then comprehensive data coverage is achieved, but it becomes difficult for physicians to track and integrate various parameters regarding device positioning and treatment efficacy
Solution Approach 1:
The patent combines multiple independent information sources (positioning data from fluoroscopy or impedance sensors, physiological measurements from tissue sensors, and operational parameters from device controllers) into a single integrated display interface. This merging allows physicians to view all parameters together in a coordinated manner, eliminating the difficulty of tracking separate parameters while maintaining comprehensive data coverage.
Solution Approach 2:
The display system is designed to universally present multiple types of information (positional, physiological, operational) through a single multi-functional interface. This universal display capability allows the system to handle diverse data types without requiring separate tracking methods for each parameter type, thereby improving ease of operation while preserving comprehensive information.
2Measurement precision
If fluoroscopy or impedance measurement methods are used to determine catheter position, then position information is obtained, but the complexity of integrating this position data with treatment efficacy data increases
Solution Approach 1:
The system merges position information from fluoroscopy or impedance measurements with treatment efficacy data by displaying both on the same interface. This integration is achieved through coordinated display techniques that show positional data and treatment outcomes together, reducing the complexity of data integration while maintaining measurement precision.
3Adaptability or versatility
If multiple sensors and measurement components are included on the catheter to treat diseased areas, then comprehensive treatment capability is achieved, but the difficulty of monitoring and guiding device position increases
Solution Approach 1:
The patent combines positioning information with treatment efficacy measurements in a single integrated display. This merging allows physicians to simultaneously monitor device position and treatment outcomes, reducing the difficulty of detecting and measuring both parameters while maintaining comprehensive treatment capability through multiple sensors and components.

This approach enables accurate tracking and modification of medical device positioning and treatment efficacy, enhancing the precision and effectiveness of medical procedures by integrating positional and physiological data for real-time decision-making.
Implementation Method 1
Another method to determine position information for an inserted medical device during cardiac procedures is to measure the opposition to time-varying electric current in an electric circuit, or impedance, provided by the tissue surrounding the target tissue. This is typically achieved by placing one or more impedance sensors or electrodes on or in the patient's body and measuring the impedance or electric potential between one of the sensors or electrodes and an electrode or sensor on the catheter.
Implementation Method 2
The treatment element may include a radiofrequency ablation element or a cryogenic ablation element
Implementation Method 3
The treatment element may include a radiofrequency ablation element or a cryogenic ablation element
