AI Technical Summary
Technical Problem
Intravascular Lithotripsy (IVL) systems face inefficiencies due to gas bubbles attenuating shockwaves, electrode erosion, operator fatigue, and manual fluid evacuation challenges, leading to reduced treatment efficacy and potential damage.
Method used
A system using separate reservoirs for inflation and evacuation fluids, with a three-way valve and automated control, enables rapid and efficient degassing by alternating between positive and negative pressures, reducing manual intervention and improving treatment efficacy.
Benefits of technology
The system enhances IVL treatment efficacy by minimizing gas bubble interference, reducing operator fatigue, and maintaining consistent shockwave intensity, thus improving treatment outcomes.

Abstract
Degassing or flushing an IVL catheter balloon. The method includes providing inflation fluid to a catheter balloon from a first fluid reservoir having a positive pressure to inflate the catheter balloon. The method further includes removing at least a portion of the inflation fluid from the catheter balloon to a second fluid reservoir, different from the first fluid reservoir having a negative pressure.
