Report

Self-sensing with hollow cylindrical transducers for histotripsy enhanced aspiration mechanical thrombectomy applications

Autor: Gong, Li, Wright, Alex R., Hynynen, Kullervo, Goertz, David E.

To address existing challenges with intravascular mechanical thrombectomy devices, a novel ultrasound-enhanced aspiration approach is being developed to mechanically degrade clots using cavitation. This method employs standing waves within a mm-scale

Report

A novel forward-looking ultrasound catheter for treating vascular occlusions

Autor: Liu, Jingjing, Wright, Alex R., Hynynen, Kullervo, Goertz, David E.

Thrombotic and chronic occlusions of large blood vessels are a major cause of mortality and morbidity, and so there is a need for improved treatments in many clinical circumstances. Endovascular ultrasound approaches have been shown to hold considera

Report

Histotripsy of blood clots within a hollow cylindrical transducer for aspiration thrombectomy applications

Autor: Gong, Li, Wright, Alex R., Hynynen, Kullervo, Goertz, David E.

Thrombolytic occlusions in stroke, pulmonary embolism and the peripheral vasculature are increasingly treated with aspiration, a catheter-based approach that employs suction to extract clots through a hollow catheter lumen. Unfortunately, aspiration

Report

Shell elasticity and viscosity of lipid-coated microbubbles are significantly altered in mediums of different ionic strength

Autor: Sojahrood, Amin Jafari, Yang, Celina, Counil, Claire, Nittachayarn, Pinunta, Goertz, David. E., Exner, Agata. A, Kolios, Michael . C.

Correct measurement of the shell properties of coated microbubbles (MBs) is essential to understanding and optimizing their response to ultrasound (US) exposure parameters in diagnostic and therapeutic ultrasound. MBs are surrounded by blood; however

Report

Intravital imaging and cavitation monitoring of antivascular ultrasound in tumor microvasculature

Autor: Zhao, Xiaoxiao, Pellow, Carly, Goertz, David E.

Focused ultrasound stimulated microbubbles have been shown to be capable of inducing blood flow shutdown and necrosis in a range of tissue types in an approach termed antivascular ultrasound or mechanical ablation. In oncology, this approach has demo
