Heart Pump with Behind-the-Ear Power Connector

One-third of patients with heart pumps develop infection at abdominal connection. Cardiac surgeons and cardiologists at the University of Maryland Heart Center are part of a multi-center clinical trial evaluating the efficacy of powering heart pumps through a skull-based connector behind the ear. The pumps, called left ventricular assist devices (LVADs), support the heart’s main pumping chamber, the left ventricle. LVADs are implanted in the chest and powered with external batteries. Typically, these devices, which are used for patients with severe heart failure, are powered through an electrical cord connected at the abdomen, where potentially deadly infections can develop.

Wireless Body Area Networks for Health Monitoring

A wireless personal health monitoring system using smartphones to upload data could revolutionize US healthcare. Faculty in the departments of electrical and computer engineering are leading research in mHealth at The University of Alabama in Huntsville. mHealth capitalizes on what Dr. Emil Jovanov, associate dean for graduate education and research in the College of Engineering, calls “major revolutions” in computer informatics, smartphones, and energy-efficient and miniaturized electronics and sensors. It can provide health information to the patient directly, to the physician via the Internet, and to researchers as aggregated databases.

Key Considerations for Integrating Wireless Technology in Medical Devices

Significant opportunities exist to incorporate wireless technology into medical devices. Wireless technology increases the effectiveness of countless every day functions. While some simply are about the convenience factor, like being able to quickly transmit patient records from one hospital to another via email, others have the power to be lifesaving. Medical device manufacturers know that there is significant opportunity to incorporate wireless technology into medical devices. However, design engineers who are extremely knowledgeable about the design of medical devices face a number of challenges in marrying off-the-shelf wireless chipsets with proprietary medical devices in development.

Micro-Endoscope as Thin as a Human Hair

Single fiber endoscope increases resolution fourfold over previous similar devices. Engineers at Stanford University have developed and demonstrated a prototype single-fiber endoscope that, they say, quadruples the resolution over existing designs, which might lead to the development of needle-thin, minimally invasive endoscopes able to view features out of reach of today’s instruments.

Managing Post-Traumatic Pain with Ultrasound Neuromodulation

This ultrasound technique is an alternative to narcotics for treating pain from acute trauma. The objective of this effort was to demonstrate the feasibility of using ultrasound induced neuromodulation (UNMOD) to manage pain. Pain management for acute trauma is generally accomplished with narcotics, which is less than ideal in a battlefield scenario. The technology of peripheral ultrasound neuromodulation (PUNMOD) offers several advantages over narcotics and current methods of neurostimulation. PUNMOD has the potential to be highly portable as a battlefield analgesic, and has the advantage of leaving the patient’s cognitive abilities intact. In addition, PUNMOD does not carry with it the risk of abuse or the need for the surveillance that is associated with pharmaceutical analgesics.
