Genetic Algorithm Optimization of Transcutaneous Energy Transmission Systems for Implantable Ventricular Assist Devices

July 3, 2013 - Bryon K, Bluvshtein V, Lucke L. Presentation at 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, July 3-7, 2013

Transcutaneous energy transmission systems (TETS) wirelessly transmit power through the skin. TETS is particularly desirable for ventricular assist devices (VADs), which currently require cables through the skin to power the implanted pump. Optimizing the inductive link of the TET system is a multi-parameter problem. In this paper, we present...



Using Value Stream Mapping to Improve Medical Device Development

April 8, 2013 - Sweem C, Crossett S, Lucke L. Presentation at Design of Medical Devices Conference, Minneapolis, MN, April 8-11, 2013

In this paper a method is presented for using value stream mapping for improving the development process of medical devices. Two examples are shown to demonstrate...



Optimization of Transcutaneous Energy Transmission Systems Suitable for Left Ventricular Assist Devices

April 8, 2013 - Bryon K, Bluvshtein V, Lucke L, Pauly J. Presentation at Design of Medical Devices Conference, Minneapolis, MN, April 8-11, 2013

Current implantable TETS systems are not optimized for high power VAD applications. Most current techniques to optimize the design simplify the problem by combining parameters leading to sub-optimal solutions. In this paper we present an optimization method using a genetic algorithm to...



Efficient Motor Control for Handheld Surgical Devices

April 10, 2012 - Bluvshtein V, Lucke L. Presentation at Design of Medical Devices Conference, Minneapolis, MN, April 10-12, 2012

Small three-phase brushless DC (BLDC) motors are well suited for hand held surgical or dental tools. The careful choice of a motor control method can reduce the heat buildup in the hand held device. In this paper we demonstrate a motor control method that can be used to reduce the temperature of...



Modeling TETS to Optimize Performance for Ventricular Assist and Artificial Heart Devices

April 10, 2012 - Bluvshtein V, Lucke L. Presentation at Design of Medical Devices Conference, Minneapolis, MN, April 10-12, 2012

Powering ventricular assist devices (VADs) or artificial hearts has always posed challenges because power has to be routed via a percutaneous cable to an implanted device. Transcutaneous energy transmission systems (TETS), or wireless power transfer through the skin, reduces the possibility of...
