1. An occlusive medical device comprising:
a braided frame comprising:
an annular distal disc portion having a radially outer surface and a radially inner surface;
an annular proximal disc portion having a radially outer surface and a radially inner surface;
a waist member extending between and connecting the annular distal disc portion to the annular proximal disc portion; and
a plurality of wires extending radially inwardly from the annular proximal disc portion toward a central position of the annular proximal disc portion,
wherein the radially inner surface of the annular distal disc portion, the waist member, and the radially inner surface of the annular proximal disc portion define an access passage through the braided frame; and
a patch closure attached to the braided frame and positioned within the braided frame to restrict access of bodily fluids through the access passage,
wherein the braided frame includes a closed end braid such that the annular distal disc is devoid of wire group tails,
wherein the plurality of wires are formed wires connecting braid wires of the braided frame to a hub at the central position.
