Biomechanical Evaluation of Tracheal Needle Puncture Forces: Comparative Analysis of Annular Ligaments and Tracheal Cartilage
(The American Society of Mechanical Engineers (ASME), 2023)Percutaneous tracheotomies (PCT) are commonly performed minimally invasive procedures involving the creation of an airway opening through an incision or puncture of the tracheal wall. While the medical intervention is ... -
Simultaneous Evaluation of Tibiofemoral and Patellofemoral Mechanics in Total Knee Arthroplasty: A Combined Experimental and Computational Approach
(The American Society of Mechanical Engineers (ASME), 2023)Contemporary total knee arthroplasty (TKA) has not fully restored natural patellofemoral (P-F) mechanics across the patient population. Previous experimental simulations have been limited in their ability to create dynamic, ... -
Using a Mock Circulatory Loop as a Regulatory Science Tool to Simulate Different Heart Failure Conditions
(The American Society of Mechanical Engineers (ASME), 2023)Mechanical circulatory support (MCS) device therapy is one of the primary treatment options for end-stage heart failure (HF), whereby a mechanical pump is integrated with the failing heart to maintain adequate tissue ... -
A Numerical Study of Crack Penetration and Deflection at the Interface Between Peritubular and Intertubular Dentin
(The American Society of Mechanical Engineers (ASME), 2024)Dentin is a biological composite exhibiting multilevel hierarchical structure, which confers excellent damage tolerance to this tissue. Despite the progress in characterization of fracture behavior of dentin, the contribution ... -
Computational Study on the Effects of Valve Orientation on the Hemodynamics and Leaflet Dynamics of Bioprosthetic Pulmonary Valves
(The American Society of Mechanical Engineers (ASME), 2024)Pulmonary valves do not display a fibrous annulus as do other valves in the heart; thus, pulmonary valves can be implanted at multiple orientations and locations within the right ventricular outflow tract (RVOT). This gives ... -
How Static and Cyclic Loading Affect the Mechanical Properties of the Porcine Annulus Fibrosus
(The American Society of Mechanical Engineers (ASME), 2024)This study sought to evaluate the effects of prolonged cyclic loading on the tissue-level mechanical properties of the spinal annulus fibrosus. Functional spinal units (FSUs) were obtained from porcine cervical spines at ... -
Detecting Toe-Off and Initial Contact in Real-Time With Self-Adapting Thresholds
(The American Society of Mechanical Engineers (ASME), 2024)This research introduces an adaptive control algorithm designed to determine gait phase in real-time using an inertial measurement unit (IMU) affixed to the shank. Focusing on detecting specific gait events, primarily ... -
Three-Dimensional-Digital Image Correlation Methodology for Kinematic Measurements of Non-Penetrating Blunt Impacts
(The American Society of Mechanical Engineers (ASME), 2024)Blunt force trauma remains a serious threat to many populations and is commonly seen in motor vehicle crashes, sports, and military environments. Effective design of helmets and protective armor should consider biomechanical ... -
Enzymatic Digestion of the Intervertebral Disc Alters Intradiscal Injection and Leakage Mechanics
(The American Society of Mechanical Engineers (ASME), 2024)Intradiscal injection is required to deliver therapeutic agents to the intervertebral disc (IVD) nucleus pulposus (NP). However, injectate leakage following needle retraction may result in decreased treatment efficacy and ... -
Experimental Analysis of Robotic Cortical Bone Specimen Drilling Performance: Effect of Cryogen
(The American Society of Mechanical Engineers (ASME), 2024)In orthopedic surgery, precise bone screw insertion is crucial for stabilizing fractures, necessitating a preliminary cortical bone drilling procedure. However, this process can induce temperatures exceeding 70 °C due to ... -
A Mathematical Model for Postimplant Collagen Remodeling in an Autologous Engineered Pulmonary Arterial Conduit
(The American Society of Mechanical Engineers (ASME), 2024)This study was undertaken to develop a mathematical model of the long-term in vivo remodeling processes in postimplanted pulmonary artery (PA) conduits. Experimental results from two extant ovine in vivo studies, wherein ... -
Residual Strain and Joint Pressurization Maintain Collagen Tension for On-Joint Lumbar Facet Capsular Ligaments
(The American Society of Mechanical Engineers (ASME), 2024)Modeling the lumbar facet capsular ligament's (FCL) mechanical behavior under various physiological motions has often been a challenge due to limited knowledge about the on-joint in situ ligament state arising from attachment ... -
Analysis of Variation in Sagittal Curvature of the Femoral Condyles
(The American Society of Mechanical Engineers (ASME), 2024)In designing femoral components, which restore native (i.e., healthy) knee kinematics, the flexion–extension (F-E) axis of the tibiofemoral joint should match that of the native knee. Because the F–E axis is governed by ... -
