P 10023: LVAD Implantation Training Simulator Dennis Prentice – Project Manager (ME) Anthony Culotta – Mechanical Engineer Jason Nichols – Mechanical Engineer Belinda Segui – Electrical Engineer Sponsor/Advisor: Dr. Steven Day Advisor: Dr. Rick Lux On Site Customers: Dr. Bill Hallinan and Dr. Todd Massey

Product Description A working replica of a human thoracic cavity to use as a surgical training device for implanting a left ventricular assist device (LVAD) Market: • Surgeons training for this surgery • Companies such as Thoratec, which create LVADs and may desire to provide training services

High Level Customer Needs Pressurized Heart Surgical Field/Confined Workspace Cleanable Replaceable Connected Tubing to Heart Ease of Storage Durability Quick Setup and Teardown Match Average Patient

System Architecture

Concept Summary Fluid/Control Subsystem to provide pressurization and proper flow rate to the heart Reservoirs and material selection provide the ability for it to be cleaned Ribs/Frame Dimension of trainer matches that of an average patient Organs/Organ Tray Incorporation of lungs, diaphragm, abdominal pocket and skin provide the appropriate surgical field and confined space

Design Summary

Test Results Control System • Labview Program and DAQ were tested with simulated inputs • Test was successful Pressure Sensor was tested to find successful calibration Pump was tested to confirm that it provides the proper pressure and flow rate needed • This was barely achieved

Test Results Continued The entire system was tested and successful integration was seen. A real heart was not obtained, so tests requiring one were not able to be performed. • Quick heart-to-tubing connector verification • Actual heart pressurization/incorporation into system • Quick setup and teardown verification

Project Status: Plan vs Execution Project is mostly on schedule • Risks mitigated: All material arrived on time Machined and built in timely fashion Lab. View successfully programmed Demo completed on time • Everything that could be tested in a timely fashion was Still need to show to Bill Hallinan and Dr Massey

$$ Budget $$ Overall proposed budget: $1, 866. 36 • The total had we not had items donated: $2, 072. 08 We spent a little over our proposed budget due to not accounting for the shipping and handling costs • Actually have a few extra materials/supplies

Overall Evaluation: MSD II went much smoother than MSD I • Followed schedule more closely • Followed Plans and design almost to the letter Met most specifications • All important needs met Test plans executed for major specs, minus ones requiring an actual heart Focused more on getting trainer built rather than testing small components for verification

From Here? It may be nice to have a 2 nd Generation of the project • Test what we could not Design to meet specs that P 10023 did not meet • Add optional features such as making the heart beat.
