Effects of Sterilization on Shape Memory Polyurethane Embolic Foam Devices
(The American Society of Mechanical Engineers (ASME), 2017)Polyurethane shape memory polymer (SMP) foams have been developed for various embolic medical devices due to their unique properties in minimally invasive biomedical applications. These polyurethane materials can be stored ... -
Feasibility Assessment of Microwave Ablation for Treating Esophageal Varices
(The American Society of Mechanical Engineers (ASME), 2017)Esophageal varices are a significant complication of portal hypertension. Endoscopic variceal ligation (EVL) is one of the clinical standards for treating these varices and preventing their hemorrhage. Limitations of EVL ... -
Force Sensing for an Instrument-Assisted Soft Tissue Manipulation Device
(The American Society of Mechanical Engineers (ASME), 2017)Instrument-assisted soft tissue manipulation (IASTM) is a form of mechanotherapy, e.g., massage, that uses rigid devices which may be machined or cast. The delivered force, which is a critical parameter during IASTM, is ... -
Lowering the Barrier of Surgical Endoscopy With a Novel Articulating Retractor
(The American Society of Mechanical Engineers (ASME), 2017)Surgical endoscopy has gained traction over the past several decades as a viable option for therapeutic interventions in the gastrointestinal tract. It utilizes natural orifice access which shortens hospital stay, minimizes ... -
Inverted L-Arm Gripper Compliant Mechanism
(The American Society of Mechanical Engineers (ASME), 2017)This work exploits the advantages of compliant mechanisms (devices that achieve their motion through the deflection of flexible members) to enable the creation of small instruments for minimally invasive surgery (MIS). ... -
Influence of a Commercial Antithrombotic Filter on the Caval Blood Flow During Neutra and Valsalva Maneuver
(The American Society of Mechanical Engineers (ASME), 2017)Anticoagulants are the treatment of choice for pulmonary embolism. When these fail or are contraindicated, vena cava filters are effective devices for preventing clots from the legs from migrating to the lung. Many ... -
An Approach for Generating an Average Bone Template With Semantic Parameters
(The American Society of Mechanical Engineers (ASME), 2017)To facilitate the design of the serialized implants and to satisfy the requirements of the population, a novel method is put forward for constructing an average bone model (ABM) with semantic parameters as a template. ... -
