A powered sit-to-stand system was utilized, which required significant design changes to the wheelchair to allow mobility in standing. In addition to describing these design changes, the paper briefly describes a two-month take-home study of N=11 Veterans with spinal cord injuries and disorders (SCI/D), including three Veterans with tetraplegia who would not have been able to use the earlier non-powered sit-to-stand system. Participants had high levels of satisfaction for durability, safety, comfort, ease of use, and effectiveness of the wheelchair. However, participants were generally not satisfied with the size and weight of the wheelchair, suggesting the need for further refinement.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...

This study gathered data that measured the usability of a multimodal wearable bioelectronic device to reliably and accurately monitor vital signs in real time. The participants (n=13) reported that the device was comfortable and adhered well during a 24-hour period, as well as easy to put on. Feedback was also collected to understand how the device might be improved, and participants shared concerns over the ability to expose the device to water (bathing, perspiration related to exercise), the size of the device, and ability to sleep wearing the device. Participant responses were consistent across collection methods (text survey during the 24 hour study period, follow-up paper survey, and follow-up phone survey). These results will inform the continued development and refinement of the device to enhance participant comfort to increase the feasibility of long-term remote management of chronic disease conditions, resulting in improved health outcomes, reduced costs, and improved quality-of-life.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...

While Thoracic Endovascular Aortic Repair (TEVAR) is the standard treatment for chronic type B aortic dissection cases, a persistent fibrotic septum often prevents complete false lumen exclusion, leading to continued pressurization and treatment failure. Endovascular septostomy is increasingly explored as an adjunctive therapy to modify this septum and promote aortic remodeling. However, current techniques carry risks such as embolic debris generation, thermal injury, and unpredictable tearing, complications that are difficult to quantify or even detect in vivo. To address these limitations, we developed a benchtop platform designed to evaluate septostomy strategies under controlled, physiologically relevant conditions. A model dissected aorta with a representative septum is integrated into a pulsatile flow loop equipped with pressure and flow sensors, thermometry, and filtration to capture debris. This setup enables the precise measurement of hemodynamic changes, thermal effects, and embolic burden, alongside visual assessment of procedural efficacy. By creating a setup that mimics physiological conditions, this platform enables the direct comparison of different septostomy methods and supports the development of improved endovascular devices.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...

Current limitations in sampling rate and the number of available recording channels in implantable systems may pose significant challenges, especially in epilepsy research where high-frequency biomarkers and multi-site monitoring are essential. The Brain Interchange (BIC) system of CorTec is an externally powered, wireless implantable system that enables sensing and stimulation up to 32 channels at 1 kHz addressing the current limitations in the field. In this study, we present a modular closed loop neuromodulation environment developed for the BIC, enabling real-time data streaming, event detection, and flexible stimulation control. The framework integrates a Simulink-based processing pipeline, real-time communication, and a graphical user interface supporting both open and closed loop paradigms. System performance was evaluated through impedance measurement, latency assessment across three stimulation modes, and real-time closed loop stimulation using electrocardiogram (ECG) for in-lab demonstration. This modular environment provides a flexible platform for developing and validating neuromodulation algorithms and can be extended to incorporate advanced biomarker detection and multi-channel neural interfaces for future clinical research.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...

However, current \"off-label\" techniques, such as mechanical \"cheese-wire\" or electrosurgical cutting, lack precision and carry significant risks of uncontrolled tearing and collateral thermal injury. To address this unmet need, we developed the Aquablade catheter, which utilizes a dual-guidewire system and a contained, athermal, high-velocity fluid jet to precisely cut the aortic septum longitudinally. This study reports the design and preliminary ex vivo benchtop evaluation of the device. Functional prototypes were tested on human aorta and standard vascular graft materials in a custom benchtop setup. The device successfully created clean, continuous longitudinal cuts through both biological tissue and synthetic graft material. Visual inspection confirmed that the device's deflector anvil protected off target areas from injury. These results validate the Aquablade's ability to perform precise, athermal septostomy without collateral damage. This technology offers a promising, safer alternative for managing complex chronic dissections, supporting further evaluation in preclinical models.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...

One non-drug intervention is graded motor imagery (GMI) that includes 3-phases (i.e., limb laterality, motor imagery, and mirror therapy). Although clinicians report patient benefit from use of GMI, barriers exist to supporting at-home use of the intervention. This report focuses on refining a mobile app (VA-GMI) through serial cognitive interviews with 12 Veterans with transtibial amputation and PLP. Following each round of interviews, we summarized the major points to guide iterative changes in the mobile app. Our first round of interviews suggested that the Veterans find the VA-GMI app acceptable, but Veterans endorsed the need for added instructions. Concurrent with these enhancements, we worked to optimize the motor imagery and mirror therapy phases. We then invited Veterans to try the new version and repeated the process. Our second round of interviews suggested the need for additional education to support Veteran understanding of pain rehabilitation. This report describes the development and testing work to date using human centered design considerations. We anticipate we will reach consensus on the VA-GMI mobile app within the next iteration.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ... Design of Medical Devices Conference.

Surgical training models are expensive and are often single-use exercises involving consumable supplies. The goal of the work presented in this paper is to increase surgeon training time by developing a surgical training simulator that is portable, inexpensive, and offers a realistic surgical environment. To achieve this goal, the device must be easily assembled, compact, durable, resistant to loads experienced during transport, and can be integrated with virtual reality training modules. This device must also work with a variety of surgical instruments, since the surgeons will be supplying their own instruments for training. The simulation environment for this project is developed with the focus of simulating laparoscopic gallbladder surgery, with the potential of extending the simulation environment for other surgeries. This paper will outline the current state of the prototype and the design process for creating the prototype.","PeriodicalId":520351,"journal":{"name":"Proceedings of the ...
