Cavitation Bubble Observation

Industry pain points and demands

Project Background & Challenges:

Vascular calcification is difficult to reverse once it occurs. Traditional treatments like balloon dilation often cause vascular injury, complications, and a high risk of restenosis.

Technical Solution & Core Challenge:
The shock wave balloon catheter delivers high-voltage pulses to induce a cavitation effect in the contrast agent. The key challenge lies in precisely controlling the rapid expansion and collapse of cavitation bubbles within an extremely short time. This process must safely and effectively generate outward shock waves to "loosen" the calcified lesions without damaging the vessel wall, thereby improving vascular compliance.

The shock waves from the balloon catheter create high-speed, randomly sized and positioned cavitation bubbles near the catheter. A high-speed camera is used to observe these bubbles and calculate shock wave speed and bubble characteristics, which helps guide product improvements.
