  1. Guidewires are used for both diagnostic and therapeutic procedures within the body. They can navigate tortuous vessel anatomy and provide a stable guiding structure along which a catheter is advanced. Current guidewires come in a variety of sizes, lengths, stiffness, compositions and tip shapes. Maneuvering and steering a guidewire within the body ...

  2. It has long been recognized that chronic stress is detrimental to overall health and plays a significant role in many diseases. Unfortunately, stress is difficult to quantify, and devices that can measure stress do not provide output in a manner that is relevant to the user. Moreover, these current devices rely on measurements of a single parameter...

  3. Magnetic resonance elastography (MRE) is a useful tool for characterizing and mapping the nonlinear viscoelastic properties of the human brain. It has shown that the stiffness of brain regions change with age and disease states. As such MRE has great utility in clinical diagnostics since many disease states are associated with changes in cellular e...

  4. Implanted electrode leads deliver a current from a powered device to tissue that requires electrical stimulation. A host of complications can arise from surgical implantation of electrode leads; however, foreign body responses and the rapid formation of a fibrotic capsule around the lead are the most frequent. Even with surface coating modification...

  5. Current implantable electrodes face many challenges in performance and biocompatibility since rigidity and flexibility cannot be satisfied at the same time. Specifically, for long-term biocompatibility and performance, implanted probes need to further reduce their size and mechanical stiffness to match that of the surrounding cells. However, this m...

  6. Haptic displays have promising applications in assistive devices for the visually impaired. However, current versions of this technology remain confined to low resolution tactile replications of images, and thus provide limited usefulness. Conventional haptic displays use motors or electrodes to convert images to touch, using an interface that is a...

  7. Carpal Tunnel Syndrome (CTS) affects roughly 3%-6% of the working population ages 18-64. This affliction is caused by applying stress on the median nerve that is routed through the carpal tunnel while it is at a positive or negative angle to the human wrist. The median nerve often becomes inflamed and swollen due to pressure from the palmar carpal ...

  8. Pervasive Brain-Mobile Interfacing (BMoI) is a new trend that has significantly increased within this decade through the creation of wearable dry contact electroencephalogram (EEG) sensors. Unfortunately, current commercially wearable brain sensors have low accuracy, power limitations and computational restraint based from mobile devices. These lim...

  9. The CDC estimates that 6.5 million people use some sort of mobility aid, such as canes, walkers, rollators or crutches. Mobility aids can be of great assistance for elderly and disabled patients. However, patients often use their mobility aids incorrectly because they cannot tell how much weight they are putting onto them and lean on them too much....

  10. With an aging population that continues to grow, more people are undergoing spinal surgeries and may need to wear a brace to stabilize their spine for a period of time afterwards. Additionally, certain spinal injuries, most notably, lumbar spondylosis, require orthoses or braces to prevent worsening of the injury. Conventional braces utilize hard p...
