Abstract:
1. A luminal occlusion device comprising: a tension member having a proximal end and a distal end; an elongate shaft having a guide structure along at least a distal portion thereof for receiving the tension member and permitting the tension member to shift between a distally extended position and a proximally retracted position relative to the shaft; and a flat film consisting essentially of a polymeric sheet structure having a total thickness in the range from 0.1 mm to 0.5 mm having an axial receptacle for receiving a distal portion of the tension member wherein a distal end of the film is attached to a distal location on the tension member and one wing extending radially outwardly from opposite sides of the axial receptacle and a proximal end of the film is attached to a distal end of the elongate shaft, wherein proximally translating the tension member relative to the shaft compacts the flat film and distally translating the tension member relative to the shaft stretches the film.
