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

Improving the Flow Environment for Cardiopulmonary Bypass v Problem: Potential aftereffects of the heartlung machine are postperfusion syndrome, hemolysis, and capillary leak syndrome. v 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. v 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.

Ambulatory Design for the Intra. Aortic Balloon Pump v Problem: The current monitoring and control system for the intra-aortic balloon pump is massive, and cannot be easily transported. v Need: An intra-aortic balloon pump better designed for ambulatory use. v Fun Fact: The console weighs 34. 8 kg, the monitor weighs 4. 3 kg, the cart weighs 29. 1 kg, and the internal battery weighs 15. 4 kg, for a total weight of 83. 6 kg (184 lbs)!

Increasing Proficiency of Balloon Angioplasty v 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. v Need: A balloon catheter that can vary in length and/or diameter. v Statistic: In 2010, Strong Memorial Hospital performed 845 interventional angioplasties.

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

Decreasing Footprint and Clutter of Machines in Operating Rooms v 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. v 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.
