A device for subcutaneous implantation of a plurality of solid, elongated medicinal pellets. The device includes a needle-like, hollow cannula within a barrel. The hub has a manually engageable knob thereon so that the hub and cannula may be easily moved with respect to the barrel with the thumb of one hand during the implantation process. An obturator extends from the rear of the barrel into the proximal end of the cannula. The obturator is composed of two or more sections which allow it to telescope during operation.

A device for inserting and positioning a plurality of elongate implants beneath the skin, comprising: a long, hollow cannula adapted for insertion beneath the skin; a hub to which the cannula is attached so as to define a continuous bore sufficiently long to contain said plurality of implants in an end-to-end relationship; a hollow body within which said hub is slidably mounted so as to move between a proximal and a distal position along an axis parallel to the continuous bore; an obturator having distal and proximal ends and including first and second sections which are connected so as to allow the first section to move with respect to the second section; means for mounting the obturator first section to the hollow body so that the continuous bore slides over the obturator as the hub is moved between the distal and proximal positions; the hub and obturator further including means for the hub to engaqe the obturator second section when the hub is first moved from the distal position to the proximal position and for moving the obturator second section in a distal direction to an extended position as the hub is subsequently moved from the proximal position to the distal position; and means, operative after the hub has been moved from the proximal position to the distal position, for maintaining the obturator second section in said extended position as the hub is moved from the distal position towards the proximal position. A device for inserting and positioning a plurality of elongate implants beneath the skin, comprising: insertion means for defining a bore, the bore being sufficiently long to contain the plurality of implants in an end-to-end relationship and including a hollow cannula adapted for insertion beneath the skin, the cannula having a bore which forms at least a part of said insertion means bore; an obturator having distal and proximal ends and including first and second sections which are connected so as to allow the first section to move with respect to the second section, the direction of movement being along an obturator axis; body means for positioning the obturator with respect to the insertion means bore so that the distal end of the obturator lies within the insertion means bore and so that the obturator axis is substantially parallel with the insertion means bore; means for moving the insertion means with respect to the obturator first section between a distal position and a proximal position; the insertion means further including means for engaging the obturator second section when the insertion means is first moved from the distal position to the proximal position and for moving the obturator second section in a distal direction to an extended position as the insertion means is subsequently moved from the proximal position to the distal position; and means, operative after the insertion means have been moved from the proximal position to the distal position, for maintaining the obturator second section in said extended position as the insertion means is moved from the distal position towards the proximal position; and wherein the body means includes a hollow housing having a closed proximal end and an open distal end within which the insertion means is slidably mounted.
