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.
Ambulatory Design for the IntraAortic 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)!
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.
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.
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.
