ABSTRACT:
An apparatus for the insertion of sterile implants comprising a cartridge having a body with a central bore. The body comprises at its proximal end a retention shoulder or hub adapted for retention by an insertion tool. The body further comprises a closure plug received in the proximal end of the bore that seals the bore and that has an exposed surface to engage a plunger rod from an insertion tool. The body still further comprises a sealed distal tip of decreasing diameter from the outer surface of the body that terminates in a point adapted for penetrating a pre-existing body orifice or for piercing tissue during insertion into a patient. The tip is frangible into a plurality of segments under pressure exerted by the distal end of the implant, allowing the implant to emerge from the cartridge.
