1. A method of manufacturing a non-implantable microvalve device for use in a therapeutic treatment in a vessel of a patient, the method comprising:
a) braiding a plurality of first filaments into a tubular form;
b) applying a base layer of a first polymer onto a mandrel;
c) providing the tubular form over the mandrel;
d) spinning the first polymer onto the tubular form;
e) removing the tubular form from the mandrel;
f) reducing a diameter of a portion of tubular form to form an end portion of the microvalve; and
g) permanently attaching the end portion of the microvalve to a catheter.
