Shock-induced collapse of a gas bubble in shockwave lithotripsy [PDF]

, 2008
The shock-induced collapse of a pre-existing nucleus near a solid surface in the focal region of a lithotripter is investigated. The entire flow field of the collapse of a single gas bubble subjected to a lithotripter pulse is simulated using a high ...

Efficacy and Safety of Intravascular Lithotripsy in the Management of Underexpanded Stents: A Systematic Review and Meta‐Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Stent underexpansion significantly heightens the risk of major adverse cardiac events (MACE), and available treatment options for this condition remain limited. Intravascular Lithotripsy (IVL) technology disrupts superficial and deep calcium by using localized pulsative sonic pressure waves, emerges as a promising tool for ...

Cavitation cloud formation and surface damage of a model stone in a high-intensity focused ultrasound field [PDF]

arXiv, 2023
This work investigates the fundamental role of cavitation bubble clouds in stone comminution by focused ultrasound. The fragmentation of stones by ultrasound has applications in medical lithotripsy for the comminution of kidney stones or gall stones, where their fragmentation is widely assumed to result from the high acoustic wave energy. However, high-

Propensity Matched Analysis of 14 French Suture‐ Versus Plug‐Based Vascular Closure During Transfemoral Transcatheter Aortic Valve Replacement (TAVR)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Plug‐based vascular closure devices (Pb‐VCD) and suture‐based vascular closure devices (Sb‐VCD) are used for percutaneous vascular access site closure during transcatheter aortic valve replacement (TAVR). Until now, no clear superiority of either device was shown in studies comparing 18 F VCDs solely.

Comparison of Procedural and Clinical Outcomes of Angiography‐ Versus Imaging‐Guided Percutaneous Coronary Intervention With Intravascular Lithotripsy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) is an innovative treatment for coronary artery calcification (CAC). Aims This study aimed to compare procedural and clinical outcomes of intracoronary imaging (ICI)‐guided percutaneous coronary intervention (PCI) versus angiography‐guided PCI with IVL in patients with CAC.

Characterisation of vent designs in flexible and navigable suction ureteric access sheaths

BJU International, Volume 135, Issue 5, Page 835-840, May 2025.
Objectives To evaluate the different vent designs in three commercially available flexible and navigable suction (FANS) access sheaths—ClearPetra® (Well lead, Guangzhou, China), Elephant II (YIGAOMedical, Hangzhou, China) and Tuohy‐Borst FANS access sheath (Seplou, Zhejiang, China)—and quantify the effects these differing designs have on the control of
