Study on the Mechanical Device, Control System, and Sensor of Biaxial Actuated Artificial Anal Sphincter Actuator for Treating Fecal Incontinence
(The American Society of Mechanical Engineers (ASME), 2024)Conventional artificial anal sphincter (AAS) did not have the capability to detect intestinal pressure, which may lead to ischemic necrosis at the clamping site or incomplete fecal release. The biaxial actuated artificial ... -
Characterization of Conventional Endovascular Devices in Treatment of Abdominal Aortic Aneurysms
(The American Society of Mechanical Engineers (ASME), 2024)Abdominal aortic aneurysms (AAA) are often repaired through an endovascular approach known as endovascular aneurysm repair (EVAR). The success and duration of these challenging procedures are primarily attributable to the ... -
Sensor-Embedded Tissue Phantom for Magnetic Resonance Elastography Mechanical Failure Testing
(The American Society of Mechanical Engineers (ASME), 2024)Magnetic Resonance Elastography (MRE) is an imaging technique capable of quantifying the stiffness of in vivo tissue by applying and imaging shear waves produced by an MRE actuator. Poor image acquisition may result from ... -
Review of Blood and Fluid Warming Methods
(The American Society of Mechanical Engineers (ASME), 2024)Warming up blood and intravenous (IV) fluids is crucial to saving lives under certain circumstances as it may prevent hypothermia during the transfusion or infusion process. Several blood and IV fluids warming methods have ... -
Utilizing Flexible Magnetic-Alloy Sheet With Rolling-to-Attaching Method to Fabricate a Smart Nail for Electromagnetic Screw-Hole Targeting in Intramedullary Interlocking-Nail Surgery
(The American Society of Mechanical Engineers (ASME), 2025)In this paper, we present a novel method to fabricate a smart nail for electromagnetic targeting of distal screw-holes in intramedullary interlocking-nail surgery. The nail is fabricated by using a flexible magnetic-alloy ... -
Comparative Survey-Based Study of Noninvasive Saliva Collection Devices
(The American Society of Mechanical Engineers (ASME), 2024)While saliva is a valuable sample for noninvasive diagnosis, the usability of saliva collection devices can impact its effectiveness in diagnostics. To address this, we evaluated five saliva collection devices: Salivette ... -
A Wearable Multichannel Electrical Stimulator for Tremor Suppression
(The American Society of Mechanical Engineers (ASME), 2024)Pathological wrist and finger tremors can be mitigated by out-of-phase stimulation of the sensory nerves in the flexor and extensor muscles. This study endeavors to develop a portable, multichannel electrical stimulator ... -
