Piezoelectric lithotripsy and soft tissue injury. Safety limits in the experimental and clinical setting.
Controversy surrounds the capacity of extracorporeal shock wave lithotripsy to cause soft tissue injury. This study examines the influence of different dosages of shock waves on the gall bladder in both humans and an animal model. Sixty one guinea pigs were divided into groups and subjected to different numbers of shock waves (6,000, 24,000, and 48,000) at different frequencies (2.5, 5.0, 10, 2...

15 صفحه اولConformal piezoelectric systems for clinical and experimental characterization of soft tissue biomechanics.
Mechanical assessment of soft biological tissues and organs has broad relevance in clinical diagnosis and treatment of disease. Existing characterization methods are invasive, lack microscale spatial resolution, and are tailored only for specific regions of the body under quasi-static conditions. Here, we develop conformal and piezoelectric devices that enable in vivo measurements of soft tissu...
