ABSTRACT:
An insertion device is provided for inserting material having an enlarged head portion into a body cavity. The insertion device includes an elongate, tubular holder, shaped for insertion into the body cavity and having an expulsion end which is dimensioned to fit over the head portion of the material and adapted to open to allow the material to be expelled therethrough; an elongate, tubular plunger, adapted to hold telescopically at least a portion of the material to be inserted, dimensioned to fit telescopically and slidably within the holder and to be movable from a telescoped position within the holder to an extended position in which one distal end of the plunger is withdrawn from the distal holder, and adapted, in the extended position, to expel the material from the device when pushed manually into the holder; and a retaining structure, interposed between the plunger and the holder and disposed at the expulsion end to engage the head portion of the material and prevent it from moving with the plunger when the plunger is moved from the telescoped to the extended position. The tubular material holder is a convolutely wound cylindrical tube, and the retaining structure is a convolutely wound cylindrical tube coaxially disposed within the tubular material holder and formed from the same blank as the tubular material holder so that the retaining structure is unitary with the tubular material holder.
