Abstract:
A method of making a covered vascular occlusion device, comprising the steps of:(a) providing the device with a braided wire member and at least first and second securing members affixed to the braided wire member at axially spaced locations, the first and second securing members being movable axially to shape a portion of the braided wire member intermediate the first and second securing members, the device being movable between a first stretched position in which the braided wire portion extends in an essentially cylindrical configuration to a maximum axial length and a minimum diameter, and a second relaxed position in which the axial length of the braided wire portion is reduced and its diameter is increased; and (b) spray coating polymeric filaments onto the braided wire member, under condition that the polymeric filaments stick to the braided wire member, for forming a film covering at least a portion of the device.
