Characterizing the Expansive Deformation of a Bioresorbable Polymer Fiber Stent
Springer Science and Business Media LLC - Tập 36 - Trang 742-751 - 2008
Polymeric vascular stents must employ other strategies than malleable deformation, as generally practiced with metal stents, to expand and withstand compressive stresses in situ. The stent expansion strategy must further consider induced flow perturbations and wall stresses that may injure the vessel wall and promote thrombogenesis. Analyzing the stresses furled stents undergo during balloon-assis...... hiện toàn bộ
MRI Robots for Needle-Based Interventions: Systems and Technology
Springer Science and Business Media LLC - Tập 46 - Trang 1479-1497 - 2018
Magnetic resonance imaging (MRI) provides high-quality soft-tissue images of anatomical structures and radiation free imaging. The research community has focused on establishing new workflows, developing new technology, and creating robotic devices to change an MRI room from a solely diagnostic room to an interventional suite, where diagnosis and intervention can both be done in the same room.

Retina Oculomics in Neurodegenerative Disease
Springer Science and Business Media LLC - Tập 51 - Trang 2708-2721 - 2023
Ophthalmic biomarkers have long played a critical role in diagnosing and managing ocular diseases. Oculomics has emerged as a field that utilizes ocular imaging biomarkers to provide insights into systemic diseases. Advances in diagnostic and imaging technologies including electroretinography, optical coherence tomography (OCT), confocal scanning laser ophthalmoscopy, fluorescence lifetime imaging...... hiện toàn bộ
Control Methods and the Performance of the Robotic Testing System for Human Musculoskeletal Joints
Springer Science and Business Media LLC - Tập 32 - Trang 889-898 - 2004
Biomechanical testing of human musculoskeletal joints not only requires qualified testing machines and devices, but also needs an excellent control method to obtain better experimental results. In this paper, we take the human functional spinal unit (FSU) as an example to study how to improve the performance of the robotic testing system. First, the mechanical characteristics of FSU are described ...... hiện toàn bộ
Combining transmural left ventricular mechanics and energetics to predict oxygen demand
Springer Science and Business Media LLC - Tập 16 - Trang 495-513 - 1988
This study relates to our earlier study which predicts the transmural distribution as well as the global left ventricular (LV) function and oxygen demand, based on the LV structure, geometry and sarcomere function. Here, we test the predicted global oxygen demand against experimental data in anesthetized, open chest dogs under changing working conditions. The experimental oxygen demand was calcula...... hiện toàn bộ
Nanoliposomal Growth Hormone and Sodium Nitrite Release from Silicone Fibers Reduces Thrombus Formation Under Flow
Springer Science and Business Media LLC - Tập 44 - Trang 2417-2430 - 2016
Biocompatibility of artificial lungs can be improved by endothelialization of hollow fibers. Bioavailability of growth-inducing and anti-thrombotic agents on the hollow fiber–blood interface inhibits thrombosis. We investigated if nanoliposomal growth-inducing growth hormone (nGH) and anti-thrombotic sodium nitrite (nNitrite) incorporation into collagen-coating on silicone hollow fibers improves b...... hiện toàn bộ
Fluid Dynamics Analysis of a Novel Micropatterned Cell Bioreactor
Springer Science and Business Media LLC - Tập 39 Số 5 - Trang 1592-1605 - 2011
Mechanical Behaviour of the Human Atria
Springer Science and Business Media LLC - - 2012
This work was aimed at providing a local mechanical characterisation of tissues from the healthy human atria. Thirty-two tissue specimens were harvested from nine adult subjects whose death was not directly related to cardiovascular diseases. Tissues were kept in Tyrode’s solution and tested using a planar biaxial device. Results showed that tissues from healthy human atria undergo large deformati...... hiện toàn bộ
