Solution Overview
Problem
Current catheters for heart interventions face challenges in accurately visualizing and maneuvering during operations, particularly when dealing with the mitral and tricuspid valves, due to the difficulty in positioning and stabilizing the catheter within confined spaces and the limitations of existing imaging technologies which suffer from wave degradation and anatomical complexities.
Innovation Solution
A catheter design featuring a hollow body with a side window for lateral beam emission and a longitudinal guiding device allowing movement and remote control of an intervention element, enabling precise visualization and alignment of the intervention area, combined with a deformable element and angular guiding devices for enhanced maneuverability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an ultrasonic probe is introduced into the heart or proximity thereof, then real-time visualization of the operation area is achieved, but overall space problems arise and it becomes difficult to convey additional medical instruments and probes
Solution Approach 1:
The patent combines the ultrasonic probe and intervention element into a single integrated catheter device. The probe is positioned at the distal end of the catheter body, allowing simultaneous visualization and intervention functions to be performed through one device rather than requiring separate instruments, thereby resolving the space occupation problem while maintaining real-time visualization capability
Solution Approach 2:
The catheter device performs multiple functions including ultrasonic imaging, intervention element deployment, and positioning within the heart. This multi-functional design eliminates the need for multiple separate devices and probes, reducing overall device complexity and space requirements while providing comprehensive diagnostic and therapeutic capabilities
2Measurement precision
If a probe is integrated into the catheter, then real-time imaging is achieved, but the device becomes difficult to handle in combination with other instruments due to large dimensions
Solution Approach 1:
The intervention element is nested within the catheter body and can be deployed when needed. This nesting approach allows the catheter to maintain a compact profile during navigation and handling while providing access to the intervention element when required, improving ease of operation without sacrificing imaging capability
Solution Approach 2:
The catheter incorporates a deformable element that can change shape and configuration to navigate complex anatomical pathways. This dynamic capability allows the device to adapt to different spatial constraints within the heart, improving handling flexibility while maintaining the integrated probe functionality
3Measurement precision
If the catheter is introduced with a defined orientation, then the probe can function, but this orientation may not be compatible with the operating mode requiring great accuracy and manoeuvrability
Solution Approach 1:
The catheter incorporates a deformable element that enables dynamic reconfiguration of the catheter body and intervention element orientation. This allows the device to adapt its shape and angle to match different operational requirements and anatomical configurations, providing both probe functionality and positioning flexibility
Solution Approach 2:
The catheter design allows for changes in geometric parameters such as curvature, angle, and orientation of the intervention element relative to the catheter axis. These parameter changes enable the device to achieve optimal positioning for different surgical approaches while maintaining probe functionality
4Adaptability or versatility
If multiple catheters are introduced to conduct different operations, then comprehensive intervention is achieved, but the risks related to operations increase
Solution Approach 1:
The patent integrates multiple functional elements including ultrasonic probe, intervention element, and deformable component into a single catheter device. This consolidation reduces the number of separate catheters and instruments that need to be introduced, thereby reducing procedural risks while maintaining the ability to perform comprehensive diagnostic and therapeutic operations
Solution Approach 2:
The single catheter device provides multiple functions including imaging, positioning, and intervention capabilities. This multi-functional approach eliminates the need for multiple separate devices, reducing the cumulative risk associated with introducing and manipulating multiple catheters while providing comprehensive operational capability

AI summary
A catheter includes a hollow body which extends longitudinally and has at least one first side window and a probe emitting a wave beam, the first side window allowing the radiation of the beam in a region next to the catheter for generating imaging, the catheter also including a longitudinal guiding device allowing a transmission of a movement to an intervention element, the intervention element moving in at least an area of the beam, the intervention angle between the first intervention element and the axis of the catheter being controlled by a remote control system.
