Functional Requirements and Quality Assurance Necessary for Successful Incorporation of Electroporation-Based Therapies Into Clinical Practice
(The American Society of Mechanical Engineers (ASME), 2020)Electroporation-based therapies have a huge potential for implementation into clinical practice in socioeconomically disadvantaged populations. Currently, the price of electroporators and electrodes is relatively high, but ... -
Improved Treatment of Postpartum Hemorrhage: Design, Development, and Bench-Top Validation of a Reusable Intrauterine Tamponade Device for Low-Resource Settings
(The American Society of Mechanical Engineers (ASME), 2020)Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide, and effective interventions for addressing PPH are urgently needed. Uterine balloon tamponade (UBT) is a technique to control PPH. Commercially ... -
Label-Free cDNA Detection Based on Radiofrequency Scattering Parameters: A New Approach for an Inexpensive Gene Sensor
(The American Society of Mechanical Engineers (ASME), 2020)A new gene detection technique that is fast, inexpensive, and easy-to-use is urgently needed in hospitals, clinics, and laboratories without access to expensive equipments. The lack of a practical, minimally invasive, and ... -
Sustainable Development: A Below-Knee Prostheses Liner for Resource Limited Environments
(The American Society of Mechanical Engineers (ASME), 2020)This research sought to develop a fabricable prosthetic liner that could be fabricable, intuitive, and a cost-effective means of providing advanced prosthetics in developing settings. An affordable ethyl-vinyl-acetate ... -
The Effect of Chemical Cleaning on Mechanical Properties of Three-Dimensional Printed Polylactic Acid
(The American Society of Mechanical Engineers (ASME), 2020)Three-dimensional (3D) printing may be a solution to shortages of equipment and spare parts in the healthcare sector of low- and middle-income countries (LMICs). Polylactic acid (PLA) for 3D printing is widely available ... -
Assessing the Usability of a Task-Shifting Device for Inserting Subcutaneous Contraceptive Implants for Use in Low-Income Countries
(The American Society of Mechanical Engineers (ASME), 2020)Women in low- and middle-income countries (LMICs) have limited access to long-acting contraceptives. Access to long-acting contraceptives, such as subcutaneous contraceptive implants, could be increased by task-shifting ... -
A Novel Intermediate Attachment to Reduce Contamination in Reusable Core Needle Biopsy Devices
(The American Society of Mechanical Engineers (ASME), 2020)One barrier to breast cancer diagnosis in low-resource settings is that devices for core needle biopsy (CNB) are either disposable and expensive, or reusable and susceptible to internal contamination. Through interviews ... -
