Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shockwave devices for treating heart valve or vascular calcification face challenges such as rapid attenuation of shockwave intensity during transmission, especially in larger tissues, and complex operation procedures that require high skill and longer times, leading to decreased success rates and increased patient burden.
Innovation Solution
A shockwave device with a guiding tip and multiple balloons, where at least two balloons are connected to the tip, each equipped with a shockwave generator and an inflatable component, distributed around the periphery, and core wires with radiopaque pieces for precise positioning, allowing for controlled shockwave generation and reduced attenuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shockwave generator is used in the center of the balloon, then the device structure is simple, but the shockwave intensity is rapidly attenuated during radial transmission to the balloon surface
Solution Approach 1:
The single central shockwave generator is segmented into multiple shockwave generators distributed around the periphery of the balloon. This segmentation allows each generator to be positioned closer to the balloon surface, reducing the transmission distance and minimizing shockwave intensity attenuation while treating calcified lesions in large-diameter vessels.
2Adaptability or versatility
If multiple balloons are spaced apart to contact different calcified lesions, then the treatment coverage is improved, but the operation becomes complicated and requires higher skill
Solution Approach 1:
Multiple shockwave generators and multiple balloons are merged into a single integrated device with a common guiding tip and delivery system. This merging allows the operator to deploy and position multiple balloons simultaneously through one device, maintaining comprehensive treatment coverage while significantly reducing operational complexity and the skill level required.
3Reliability
If multiple balloons are used to treat different calcified lesions, then the treatment effectiveness is improved, but the operation time increases
Solution Approach 1:
Multiple balloons are pre-positioned and pre-inflated within the single device before deployment. This preliminary preparation allows the operator to treat multiple calcified lesions in sequence without requiring repeated device insertions or complex repositioning, thereby maintaining high treatment effectiveness while reducing total operation time.
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
The device effectively inhibits shockwave attenuation and simplifies the operation by reducing the skill required, shortening procedure time, and improving success rates while minimizing risks and patient burden.
Implementation Method 1
The shockwave generated by the shockwave generator 920 is radially transmitted to the surface of the balloon 910 via the liquid, and then further transmitted to the calcified lesions via the surface of the balloon
Implementation Method 2
The shockwave generator 920 includes an electrode cable for receiving and transmitting electrical voltage/electrical current pulses and an electrode probe 922 for receiving electrical voltage/electrical current pulses to generate shockwaves
Implementation Method 3
The shockwave generated by the shockwave generator 920 is radially transmitted to the surface of the balloon 910 via the liquid
Implementation Method 4
When the shock wave is transmitted to the calcified lesions, the calcified tissues in the calcified lesions are fractured due to the compression stress of the shock wave
