Simulation in surgical training is a growing field and this study aims to understand the force and torque experienced during lumbar spine surgery to design simulator haptic feedback. It was hypothesized that force and torque would differ among lumbar spine levels and the amount of tissue removed by ≥ 7%, which would be detectable to a user. Force a...
Simulation is an essential component in training, from animal models for surgeons to virtual reality flight simulators for pilots. New medical advances have increased the need for specialized training platforms. This thesis focused on one intervention for the treatment of the leading cause of disability worldwide: low back pain and lumbar interbody...
Robotic devices are commonly used in surgical simulators to provide tactile, or haptic, feedback. They can provide customized feedback that can be rapidly modified with minimal hardware changes in comparison to non-robotic systems. This work describes the design, development, and evaluation of one such tool: a novel uniaxial torque haptic device fo...
Background
PPODA-QT is a novel liquid embolic under development for the treatment of cerebral aneurysms. We sought to test the rabbit-elastase aneurysm model to evaluate the tissue response following PPODA-QT embolization.
Methods
Experimental elastase-induced aneurysms were created in fourteen New Zealand White Rabbits. Eight animals were used fo...
This poster is a comparison of energy loss in the hysteresis torque curve during a lumbar discectomy. It can be viewed at: https://www.epostervirtual2020.eurospine.org/cm_data/eposter/P4.PDF
This work addresses the current lack of robotic haptic torque devices in virtual reality and augmented reality (VR/AR) surgical training platforms. A torque handle that can augment existing haptic force devices has been designed to produce up to 3N-m of continuous torque at 38rpm. This device will be used to expand the scope and perceived realism o...
Introduction
PPODA-QT is a novel liquid embolic under development for the treatment of cerebral aneurysms. The material is prepared and undergoes gelation in a predictable manner over a pre-set length of time for controllable delivery to the aneurysm with balloon protection. We utilized a rabbit-elastase aneurysm model with histological analysis to...
To refine the development of novel endovascular devices and materials,
innovative experimental testing methods can assess blood flow effects, material
fatigue, downstream migration, and particulation. Specifically, in vivo animal
models are not ideal for assessment of downstream particulation. This study
describes the development of an in vitro neu...
Introduction/purpose
While advances in microcatheters have facilitated access to the distal neurovasculature, current embolization strategies have difficulty achieving long-term aneurysm occlusion. Liquid embolics have the potential to completely fill aneurysms, which may result in improved long-term occlusion. However, the only available liquid em...

Cerebral aneurysms can be found in over 2% of the American population, and their rupture into hemorrhagic stroke carries a 40% mortality rate. This makes their treatment important to clinicians trying to prevent this from happening to millions of people. A novel polymer, poly(propylene glycol) diacrylate and pentaerythritol tetrakis (3-mercaptoprop...
Background
Untreated ischemic stroke can lead to severe morbidity and death, and as such, there are numerous endovascular blood-clot removal (thrombectomy) devices approved for human use. Human thrombi types are highly variable and are typically classified in qualitative terms – ‘soft/red,’ ‘hard/white,’ or ‘aged/calcified.’ Quantifying human throm...

We developed an automated system that can be used to decellularize whole human-sized organs and have shown lung as an example. Lungs from 20-30kg pigs were excised en bloc with the trachea and decellularized with our established protocol of distilled water, detergents, sodium chloride and porcine pancreatic DNase. A software program was written to...
Human induced pluripotent stem cells (hiPSCs) grown in multiple culture media were altered after being subjected to a stretching protocol. hiPSC maintenance media and Gray's media were used during the 6 day stretching protocol of 0.1 Hz with 5% circular elongation. While the final state of their development remains a mystery, qPCR using pluripotent...
