Physiologic Waveforms

Abdominal Aorta & Renal Arteries

This data contains realistic physiologic waveforms for the renal flow and the infra-renal aortic flow, as well as for the abdominal aortic pressure. Two physiological conditions are included: resting and light exercise. The data represents a normal adult, and is based on simulations which use realistic aortic flows and renal/iliac outlet impedances.

Simulation Source Codes

Fontan Exercise Physiology Model

This package contains the source codes for running 0D lumped-parameter simulations to model Fontan exercise physiology. The model inputs are patient weight, height, and exercise intensity. The model then performs a simulation to produce the presure, flow, and volume waveforms at various anatomical locations for the average Fontan patient with those input characteristics.

Design & Geometries

Abdominal Aortic Aneurysm flow phantom

This package contains Parasolid files which can be directly used in a rapid-prototyping machine to print an AAA flow phantom for experiments. The geometry can also be directly used in a CFD simulation of blood flow. The phantom geometry is based on a patient-specific AAA, and contains the beginning segments of the renal and iliac arteries. The phantom has one inlet and two outlets.

Physical Resistor-Capacitor-Resistor Module

This package contains Solidworks files with the design to construct a physical RCR module for reproducing realistic vascular impedances for flow experiments. The design allows for a stable operation and accurate adjustment of the resulting impedance. The capacitor module assembly contains an inlet region to minimize parasitic resistance, allowing it to perform closely as an ideal capacitor.
