Abstract
We propose an innovative way to “assist” the Fontan circulation by creating a novel bifurcating graft (IJS) .A benchtop dynamically scaled mock flow loop (MFL) will be configured to validate the optimized IJS .The MFL will be based on a reduced Fontan lumped-parameter model (LPM) and will be comprised of an upper body and lower body RLC compartments as well as a left and right lung RLC compartments. A patient-specific 3D model of the Fontan junction is produced via 3D printing and is the centerpiece of the MFL. A steady flow pump maintains the mean flow, matching the target cardiac output, for the baseline “sick” Fontan circulation, and, with the IJS, a Harvard Medical pulsatile pump provides the targeted flow rate through the IJS. Flow and pressure sensor data at critical points in the MFL are acquired via a National Instruments multichannel data acquisition board and processed using LabView.
