  1. Clinical Needs Presentation Christopher Troiano RIT Mechanical Engineering

  2. Clinical Needs • Improving the Flow Environment for Cardiopulmonary Bypass • Ambulatory Design for the Intra-Aortic Balloon Pump • Increasing Proficiency of Balloon Angioplasty • Adapting Wire Technology for Increased Control • Decreasing Footprint and Clutter of Machines in Operating Rooms

  3. Improving the Flow Environment for Cardiopulmonary Bypass • Problem: Potential aftereffects of the heart-lung machine are postperfusion syndrome, hemolysis, and capillary leak syndrome. • Need: An alteration to the flow environment – allowing for pulsatile flow over continuous flow, filtering of microemboli and debris from the circuit, and altering the centrifuge to incur less red blood cell damage. • Statistics: In a study posted by the New England Journal of Medicine, 53% of bypass patients experience cognitive decline at discharge, 36% at six weeks, 24% at six months, and 42% at five years.

  4. Ambulatory Design for the Intra-Aortic Balloon Pump • Problem: The current monitoring and control system for the intra-aortic balloon pump is massive, and cannot be easily transported. • Need: An intra-aortic balloon pump better designed for ambulatory use. • Fun Fact: The console weighs 34.8kg, the monitor weighs 4.3kg, the cart weighs 29.1kg, and the internal battery weighs 15.4kg, for a total weight of 83.6kg (184lbs)!

  5. Increasing Proficiency of Balloon Angioplasty • Problem: Angioplasty procedures commonly require more than one balloon to be used. This is wasteful in regards to the time and cost the hospital must spend on the procedure. • Need: A balloon catheter that can vary in length and/or diameter. • Statistic: In 2010, Strong Memorial Hospital performed 845 interventional angioplasties.

  6. Adapting Wire Technology for Increased Control • Problem: Surgeons occasional have trouble accessing arteries during diagnostic catherizations. Access can require the use of various sheaths and guide wires. • Need: A wire that could alter its shape without sacrificing stiffness. • Statistics: In 2010, Strong Memorial Hospital performed 2,652 vascular catherizations and 3,220 cardiac catherizations.

  7. Decreasing Footprint and Clutter of Machines in Operating Rooms • Problem: Operating rooms, with special notice of cardiac surgery rooms, contain numerous monitoring machines. There is a lot of clutter, particularly with wires, and the importance of each machine requires the physiologists to constantly move to monitor each machine. • Need: The development of a single, modular unit that can accept data from multiple machines, allowing for one central machine to retrieve all diagnostic data.
