Generating Appropriate and Reliable Evidence for Value Assessment of Medical Devices: An ISPOR Medical Devices and Diagnostics Special Interest Group Report
(The American Society of Mechanical Engineers (ASME), 2022)Health technology assessment (HTA) methods have become an important health policy tool to assess value. Yet recommendations for what constitutes appropriate and reliable evidence and methodologies for assessment of medical ... -
Fully Closed Loop Test Environment for Adaptive Implantable Neural Stimulators Using Computational Models
(The American Society of Mechanical Engineers (ASME), 2022)Implantable brain stimulation devices continue to be developed to treat and monitor brain conditions. As the complexity of these devices grows to include adaptive neuromodulation therapy, validating the operation and ... -
Extravascular Cooling of Blood Using a Concentrated Thermoelectric Cooling Probe
(The American Society of Mechanical Engineers (ASME), 2022)Thermal therapies have strong potential for improving outcomes for patients suffering from cardiac arrest, neonatal hypoxic-ischemic encephalopathy, or medically refractory intracranial hypertension. We propose a novel ... -
A Retractable Six-Prong Laparoscopic Grasper for Laparoscopic Myomectomy
(The American Society of Mechanical Engineers (ASME), 2022)The fixation and manipulation of fibroids during laparoscopic myomectomy is a persistent issue for gynecologic surgeons. In this paper, we present a laparoscopic grasper that, through a sheath-based deployment mechanism, ... -
Finite Element Analysis and Bench Testing of Ventricular Septal Defect Occluder
(The American Society of Mechanical Engineers (ASME), 2022)The mechanical behavior of the ventricular septal defect (VSD) occluder is strongly linked to complications following transcatheter closure of the VSD. Methods: A mechanical model of the VSD occluder was constructed by ... -
A Novel Approach to Open Reduction and Internal Fixation of Distal Radius Fractures Utilizing a Multi-Degree-of-Freedom Traction and Stabilization Device
(The American Society of Mechanical Engineers (ASME), 2022)Open reduction and internal fixation (ORIF) is a surgical procedure performed with the objectives of restoring normal alignment and providing stability to broken bone fragments after a fracture. This procedure is increasingly ... -
Effect of Leaflet Type and Leaflet-Stent Attachment Height on Transcatheter Aortic Valve Leaflet Thrombosis Potential
(The American Society of Mechanical Engineers (ASME), 2022)Transcatheter aortic valve replacement devices vary in leaflet material and in the height for which leaflets attach to the stented valve frame. Combinations of these features can influence leaflet dynamics, neo-sinus ... -
Pre-Operative Motion Planner for Steerable Needles Using Cost Map Based on Repulsive Field and Empirical Model of Needle Deflection
(The American Society of Mechanical Engineers (ASME), 2022)Needle insertion is a common procedure in percutaneous puncture. A motion planner for a steerable needle that considers the risk level of the path in anatomical environment and the actual deflection of clinical needle is ... -
Development of a pO2-Guided Fine Needle Tumor Biopsy Device
(The American Society of Mechanical Engineers (ASME), 2022)Tumor biopsies are an important aspect of oncology providing a guide for medical treatment and evaluation of disease progression. Highly heterogenous tumors have complex regions of active cancer cells interdigitated with ... -
Design and Preliminary Validation of Grasp Assistive Device for an Industrial Environment
(The American Society of Mechanical Engineers (ASME), 2022)Carpal tunnel syndrome and tendonitis are two common upper extremity cumulative trauma disorders (CTD) related to repetitive and forceful activities in industrial environments. Reducing the muscular force during activities ... -
Protective Masks Utilizing Nonendangered Components
(The American Society of Mechanical Engineers (ASME), 2022)At the beginning of the COVID-19 pandemic when traditional N95 respirators were in short supply in the United States, there was a need for alternative products that did not rely on traditional avenues of sourcing and ... -
Early Experiences Designing a Scalable COVID-19 Reusable Elastomeric Respirator
(The American Society of Mechanical Engineers (ASME), 2022)The COVID-19 pandemic created an unprecedented shortage of personal protective equipment (PPE) for healthcare workers—especially respirators. In response to a lack of commercial respirator equipment, a multidisciplinary ... -
