  1. 11022 Transcutaneous Signal Transmission for LVAD October 8 , 2010 Yevgeniy Popovskiy, Vince Antonicelli, Craig LaMendola , Chrystal Andreozzi

  2. System Level Design Review Agenda • Project Background • Project Scope and Objective • Project Schedule • Customer Requirements • Engineering specifications • Work Breakdown • System Concept Generation, Scoring and Selection • Case • Insulation/ wire • Electrical System • Risks Assessment • Project Budget • Next Steps • Questions and discussion

  3. Project Background The primary objective of this project is to design a transmission system to safely and affectively transfer power and control signal from the external power supply and control to the Left Ventricular Assist Device(LVAD).

  4. Project Objectives MSD II • Objectives • Assumable system • Troubleshoot design • Testing equipment • Deliverables • Working System • Test data to support design MSD I • Objectives • Concept Generation and Selection • Detailed Design • Ready for Construction • Deliverables • Finalizes design • Order parts • Finalize Test specification

  5. Senior Design I Schedule

  6. Work Breakdown

  7. Customer Needs THE SYSTEM NEEDS TO WORK!!!! The device must be reliable (Must produce a continuous power and control signs) The number of wires needs to be reduced The cable diameter needs to be reduced The cable needs to be more flexible Meet FDA standards or be able to be modified to meet FDA standards

  8. Engineering Specification Reliable Operation 6 hours Cable Size ~3mm Improve Cable Flexibility 200% Internal/ External Volume 450 cm3 Eternal Weight 0.9 kg Cost below $3500

  9. System Overview

  10. Outer ProtectionProtective outer layers 1st Line of Defense • Wire port sealing

  11. Sealing Methods 2nd Line of Defense Types of O-rings O-ring grooves

  12. Protective CaseCase Structural material

  13. Case Concept Selection

  14. Insulation. • Heatsink Pad • Remain sold at room temperature and then soften at heatsink operating temperature • Heatsink paste/grease • Pasted applied directly to component

  15. Insulation Cont. Electrical Potting • Epoxy • Stable material (hard) • Resistance to temp. up to 200 oC • Very good resistance to chemicals • Cracks easily

  16. Wire • Wire Types • Calmont Wire and Cable • Stranded Single-Conductor (P10022) • Thoratec Corporation (HeartMate II)

  17. Insulation and Wire Concept Selection
