Abstract:
A method of making a covered vascular occlusion device, comprising the steps of:(a) stretching a portion of film to form a shape similar to a portion of a device to be covered by the film, the device comprising 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 moveable 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;(b) inserting the device into the shape formed in the film so that the film covers at least a portion of the device; and(c) trimming the film to separate the covered device from the remaining film.
