Pulmonary artery flow restrictors for transcatheter placement in neonates with congenital heart disease
This project has been secured to protect intellectual property.
Login for More InformationDesigning a more efficient pulmonary artery flow restrictor for neonates with congenital heart disease so that the device shows no distal migration and the amount of restriction can be quantified and changed.
Project Overview
Left-to-right heart shunts are a type of congenital heart disease that impacts the heart’s ability to pump blood effectively. In this condition, pulmonary blood flow to the lungs can be excessive which can lead to many major complications such as pulmonary edema and heart failure. Patients with large, life threatening left-to-right heart shunts present symptoms at birth, therefore, most patients being treated with these conditions are infants.
The goal of this project is to create a pulmonary artery flow restrictor that will limit the volume of blood entering the pulmonary circulation to normal physiological levels. The device must be deployed and placed via catheter into the pulmonary artery through the venous system. In addition, it should have the ability to precisely limit blood flow based on a patient’s size.
