SYST

Design and produce a commercially viable Transcutaneous Energy Transfer system with the ability to power a left ventricular assist device (LVAD). This TETS device will use a magnetic coupling to enhance the patients quality of life

while operating in a safe, efficient, reliable and user friendly manner.

Senior Design

MER I T

1) Contrast white ribbing helps adds contrast and memory encoding for consis-tent adjusting to correct size 2) gray ribbing adds addi-tional contrast to white rib-bing for visability

Tri-paneling makes the belt more intuitive to wear (center aligns on back)

Optional customization of housing

Even with the addition of numerous new features, future iterations of this project could benefit greatly from smaller, biocompatible (UHMWPE or PEEK) cases and a smaller, more powerful battery. The addition of another battery to power the external unit would allow this device to become truly portable. Greater investment into a motor and generator pair will be needed in order to pursue better packaging and power transfer results.

Useful Power was converted from an AC wall outlet to an internal DC battery charge voltage. This was transferred over an air- gap using magnetic coupling. The status of the internal battery voltage can be displayed on the user interface and ramp with a push button start.

Since this project is beginning from the starting point of having a working prototype of the TET system, this team focused on the implementation of that technology as an implantable system by creating a user interface (UI) to start the device, and power con-ditioning circuits that allow the power to be used to charge a battery. This can provide reliable power to an LVAD pump.
