Of this, $15B is spent on foot ulcer treatment alone as more than half of people with diabetes develop some type of neuropathy, the primary modifiable risk factor of ulcers in this population. Currently, patients with diabetic peripheral neuropathy (DPN) rely on early hotspot identification, padded soles, offloading boots, and diabetic shoes, with compliance being the major issue. Through expert interviews, there is a need for a better method to slow and prevent the progression of hot spots and other complications in patients with DPN. Our team is proposing DiaSense, a wearable device that replaces the lost sensation of pain with a safe and actionable stimulus that modifies gait to offload hotspots. The discrete design was guided by experiences from patients, podiatrists, and vascular surgeons to improve patient compliance, satisfaction, and recovery. Early user-feedback demonstrated useful validation that our device modifies walking behavior in healthy participants, and helps justify a larger study with patients who have diabetic peripheral neuropathy.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125844329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While it is known that kangaroo care, or more simply, skin-to-skin contact, can lead to better health outcomes for both the infant and the mother, the correlation between duration of kangaroo care and positive health outcomes remains a mystery. Not all mothers are able to perform kangaroo mother care, or 24-hour kangaroo care, so it is important to know how much kangaroo care is necessary to achieve positive health outcomes for infants born prematurely. To determine the relationship between maternal-infant interactions, a system of health monitoring devices is presented to measure the duration and frequency of kangaroo care, along with the effects of kangaroo care before, during, and after the act. One specific parameter of interest is the heartrate of the mother and infant. The maternal heartrate can be measured with a commercially available Garmin Venu® Sq smartwatch, but it typically cannot be worn on the wrist in NICUs due to their infection control guidelines. The viability of wearing a Garmin® smartwatch to measure maternal heartrate on the ankle or bicep compared to the wrist was determined by wearing three smartwatches simultaneously on the specified locations. It was found that the smartwatch located at the ankle undercounted the heartrate by an average of 0.5 bpm and the smartwatch located at the bicep overcounted by an average of 0.05 bpm. From statistical analysis, it was determined that the smartwatch worn at the bicep would be an acceptable alternative to wearing a smartwatch on the wrist to gather maternal heartrate data for use in the complete kangaroo care monitoring system.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"149 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130150309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As more people suffer from stroke, there is a growing need for rehabilitation. Rehabilitation robots have been proven effective in assisting patients in their rehabilitation process. However, many existing rehabilitation robots are costly, so the accessibility to patients in need is limited. Soft robot technology has great potential to make rehabilitation more accessible. This paper presents a proof-of-concept soft robot design that could be used for finger rehabilitation, especially for those who suffer from clenched fists after a stroke. Using silicone elastomer and pneumatic actuation, we successfully fabricated a soft robot that curled in its resting state to fit under the patient’s clenched fist and straightened when actuated by compressed air to push the patient’s fingers open. With a unique approach to bonding the two-layer silicone elastomer structure, our soft robot can change shape to straight from its original curling state with a small air pressure (2 to 3 psi). Preliminary testing results demonstrate our soft robot’s functionality and provide valuable insights for us to optimize our design further to reach our eventual goal as a rehabilitation device that assists finger rehabilitation.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128614663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It utilizes 3D models from pre-operative CT, via 3D-to-2D registration methods, to update object poses based on 2D fluoroscopic images. However, on occasion pre-operative CT images may be unavailable. We developed a CT-free method to enable BGS use that leverages neural radiance fields (NeRF) to generate a continuous volumetric scene [2,3] from intra-operative fluoroscopy. For proof of concept, digitally reconstructed radiographs (DRRs) were created from pelvic CT data as a stand-in for intra-operative fluoroscopy. DRRs and virtual C-arm positions were fed into an existing NeRF scene reconstruction system,[2,3] and bones were segmented from the reconstruction. The accuracy of NeRF-derived segmentations was evaluated by comparison to gold-standard CT segmentation. The number of input DRRs was varied to study how this parameter influences reconstructions. Volume reconstructions were readily obtained using the NeRF scene reconstruction system. RMS errors of the NeRF-derived segmentations ranged from 1.23 mm when using 36 input DRR images to 1.98 mm when using only 8 input DRR images. Based on this performance, we conclude that CT-free NeRF volume reconstruction from intra-operative fluoroscopy holds great potential for use in surgical navigation applications involving bony procedures.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120931915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coronary artery occlusion (CAO) following the implantation of the device is a potential complication with a high mortality rate, as CAO causes a deterioration of coronary perfusion, followed by cardiogenic shock and electrical instability. Due to this dangerous potential complication, bailout percutaneous coronary intervention (PCI) techniques, like the snorkel and chimney techniques, have been developed as an effective strategy for ensuring coronary perfusion is maintained following a TAVR procedure. Both snorkel and chimney techniques have been implemented in a reanimated swine and human heart respectively utilizing Visible Heart® methodologies. The procedures have been recorded utilizing endoscopic cameras, echocardiography, optical coherence tomography, and fluoroscopy. Post-procedural micro-computed tomography (micro-CT) was conducted to provide post-implantation imaging with approximately 60-micron resolution. The reconstructions are then segmented and used to create 3D renderings of these complex procedures. These methodologies are repeatable and can be used in a variety of conditions to be used in subsequent educational uses.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134021084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
