Wednesday, March 27 | 5:45-7:45 pm
ABOUT THIS TUTORIAL:
Manufacturer’s requirements for safe, higher energy density batteries for many implantable, wearable, surgical and portable medical devices continue to grow exponentially. Wireless rechargeable batteries which are critical for many implantable applications are at the forefront of battery technology. This tutorial will provide engineers, designers, product managers, component and materials suppliers with an interactive overview of the design criteria and specifications that should be taken into consideration for medical devices including implants, wearables and surgical tools. Some of the topics that will be covered include design, safety, reliability, size, weight, power output, battery life, charging and cost.
TUTORIAL AGENDA:
5:45 Course Introduction and Start Dinner
6:05 Batteries for Medical Devices: Enabling medical device innovation and Delivering Value-based Health Care
Gaurav Jain, PhD, Technical Fellow and Director of Energy Systems Research & Technology, Medtronic, Inc.
Battery technologies are a critical building block to meet the rapidly expanding healthcare needs. For battery experts, this is an exciting area with steady business demand, appetite for meaningful innovation and opportunities to have significant societal impact. This talk will present considerations for battery technologies for implantable, devices, wearable devices and various other types of medical applications. The needs for small primary cells to large multi-cell rechargeable battery packs will be discussed. Key unmet demands and approaches to ensure safety, quality & reliability will be discussed.
6:25 Battery Gauging and State of Health Indication for Medical Devices
Yevgen Barsukov, PhD, Head of algorithm development, Battery Management Systems, Texas Instruments, Inc.
Reliable medical device operation is essential due to life saving functions of many of these devices. Since battery state determines to large extent the operation capability of portable medical devices, battery gauge is essential to accurately predict remaining run-time and to allow warning action if battery is running close to end of useable capacity. In this presentation, I will describe basic choices in existing gauging solutions, as well as cover more advanced functionality such as reporting actual useable capacity at given rate of discharge and temperature. Reporting of Wh vs Ah remaining capacity will also be cowered as it is important for estimating the remaining run-time for most medical devices which operate under constant power mode. In addition, I will discuss the critical need for battery state of health indication for medical devices, since replacing a battery that can result in unexpected loss of function can prevent life-threatening situations in medical devices.
6:45 Life-Enhancing Advancements in Batteries for Implantable Medical Devices
Robert Rubino, Sr. Director, Research and Development, Integer, Inc.
Active implantable medical devices, such as pacemakers, have been successfully powered by implanted batteries for 60 years. The success of the pacemaker has fueled the development of multiple other types of devices such as defibrillators, sensors, and neurostimulators. In order to enable and improve these life-enhancing devices, power technologies have evolved to provide reliable and improved output resulting in more patient-friendly devices with enhanced functionality.
7:05 Batteries for Medical Devices: Regulatory topics, Challenges and Opportunities
Iacovos Kyprianou, PhD, Senior Science Health Advisor, FDA
The mission of the Center for Devices and Radiological Health is to protect and promote public health. A subset of the medical devices we regulate are battery powered. As batteries become more powerful and more reliable and electronics become smaller and more widespread, the trend is to see more and more medical devices becoming mobile and to use batteries as their main or backup power source. At the same time a number of health related organizations have identified batteries as one of their top challenges. In this talk we will discuss some of the challenges related to battery powered medical devices as well as the opportunities for improving their safety and reliability.
