Claim:
1. A medical device for occluding a patent ductus arteriosus between an aorta and a pulmonary artery, the medical device comprising: only one layer of braided fabric; wherein the only one layer of braided fabric forms a tubular member having proximal and distal ends; wherein the tubular member comprises a proximal disk-shaped portion at the proximal end and a distal disk-shaped portion at the distal end and a geometrical-shaped portion disposed therebetween, each of the proximal and distal disk-shaped portions having a maximum cross-sectional dimension larger than the geometrical shaped portion, the proximal disk-shaped portion having a maximum diameter at a distal end thereof and the distal disk-shaped portion having a maximum diameter at a proximal end thereof; wherein the tubular member further comprises a transition segment coupled to either of the proximal or distal disk-shaped portions and the geometrical-shaped portion, the transition segment having a maximum cross-sectional dimension smaller than both the proximal and distal disk-shaped portions and the geometrical shaped portion, wherein each of the proximal disk-shaped portion maximum diameter and the distal disk-shaped portion maximum diameter extend inwardly to overlap the respective transition segment; and wherein the only one layer of braided fabric is configured to be constrained within a catheter having an outer diameter of about 5 French or smaller for percutaneous delivery to the patent ductus arteriosus.
