Purpose Passive removal of stone fragments in the irrigation stream is one of the
characteristics in continuous-flow PCNL instruments. So far the physical principle of this so …

Background Studies have identified hemodynamic shear stress as an important determinant
of endothelial function and atherosclerosis. In this study, we assess the influences of …

Objectives This study sought to explore the efficacy of the conical stent implantation in the
coronary artery by comparing the effects of cylindrical and conical stents on wall shear stress …

Objective: This work aims to develop a novel approach for in vivo quantitative imaging of
coronary blood flow using intracoronary Doppler OCT. Methods: A 200 kHz swept-source …

Cerebral aneurysms are an abnormal ballooning of blood vessels which have the potential
to rupture and cause hemorrhagic stroke. The diagnosis, treatment, and monitoring of …

Herein, we demonstrate a method of intravascular catheter-based extrusion of hydrogels
with in situ photomodulation to dynamically adjust the hydrogel properties utilizing a custom …

Carotid atherosclerosis is a critical medical concern that can lead to ischemic stroke. Local
hemodynamic patterns have also been associated with the development of atherosclerosis …

Carotid artery stenting (CAS) is currently the standard of care for carotid atherosclerotic
lesions. The goal of CAS is to provide support for the arterial wall and attempt to restore …
