Solution Overview
Problem
Conventional intravascular lithotripsy catheter systems lack user interfaces that provide comprehensive operational information, requiring clinicians to rely on external devices for relevant data during procedures.
Innovation Solution
A catheter system with an integrated graphical user interface (GUI) that displays operational information, including catheter type, balloon dimensions, emitter arrangement, shot counts, pressure information, and allows touchscreen control of components, enhancing user interaction and data visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional intravascular lithotripsy catheter systems use minimal user interfaces, then device complexity is reduced, but loss of information increases as clinicians must rely on external devices for operational data
Solution Approach 1:
The patent combines the user interface, display system, and control functions into an integrated console that is part of the intravascular lithotripsy system. This merging eliminates the need for separate external devices (timers, pressure gauges) and consolidates all operational information display and control functions into a single integrated unit, thereby reducing information loss while managing overall system complexity.
Solution Approach 2:
The console serves multiple functions simultaneously: it displays operational parameters (pressure, temperature, flow rate), controls the lithotripsy procedure, and provides real-time monitoring. This multi-functionality consolidates what would otherwise require multiple separate devices into one universal interface, reducing information loss without proportionally increasing complexity.
2Ease of operation
If conventional catheter systems require external devices for monitoring, then device complexity is reduced, but ease of operation deteriorates as clinicians must manage multiple devices
Solution Approach 1:
By merging the display, control, and monitoring functions into a single console interface, the system improves ease of operation. Clinicians interact with one unified system rather than coordinating multiple separate devices, making procedure control more straightforward while the integrated design manages the complexity of system integration.
3Loss of information
If comprehensive operational information is displayed, then loss of information is reduced, but device complexity increases due to integrated GUI and control systems
Solution Approach 1:
The console provides comprehensive display of operational parameters (pressure, temperature, flow rate, timer) and controls multiple system functions through a single multi-functional interface. This universal approach reduces information loss by consolidating all data in one place while managing complexity through integrated design rather than multiple separate systems.

Function Achieved in This Case
The GUI provides real-time operational data and control, improving the efficiency and effectiveness of intravascular lithotripsy procedures by reducing reliance on external devices and enhancing user interaction.
Implementation Method 1
a high energy source is used to provide energy to an energy guide and/or an emitter in order to generate plasma and, ultimately, pressure waves
Implementation Method 2
generate plasma and, ultimately, pressure waves as well as a rapid bubble expansion within a fluid-filled balloon to crack calcification
Implementation Method 3
utilizes a combination of pressure waves and bubble dynamics that are generated intravascularly in a fluid-filled balloon catheter
Implementation Method 4
The rapid change in fluid momentum upon hitting the balloon wall is known as hydraulic shock or water hammer
