Abstract
Official abstract text for this publication.
A pulmonary artery flow restrictor system includes a funnel shaped membrane with a proximal base, a restrictive distal opening which is stretchable to larger sizes, an internal strut structure, and an external stent structure.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of treating congenital heart disease in infants, the method comprising: using a transcatheter device to deploy a collapsed funnel shaped membrane, an internal strut structure, and an external stent structure to the pulmonary artery of an infant or child; expanding the funnel shaped membrane, the internal strut structure, and the external stent structure in the pulmonary artery so the membrane forces blood in the pulmonary artery to flow out a narrower area distal opening resisting blood flow through the pulmonary artery to lower the blood flow rate therein; and as the infant grows, using a balloon catheter to expand the narrower area distal opening to increase the blood flow rate through the funnel shaped membrane.
