Claim:
A subcutaneous implantation instrument, comprising: a syringe body comprising a non-cylindrical shaft that axially defines a non-circular bore continuously throughout the length of the shaft, wherein the bore comprises a cross section of at least five millimeters in at least one orientation; a non-cylindrical incising shaft comprising: an incising shaft body that axially defines a non-circular bore sized to match the bore of the syringe body: a beveled cutting blade comprising a beveled surface on a distal face of the incising shaft body and a straight and sharpened cutting edge cutting edge with rounded ends on each side of the cutting edge that curve inwardly, wherein the cutting edge is defined only along a bottom distal edge of the beveled tip; and an attachment surface formed on a proximal end of the incising shaft body, wherein the incising shaft is fixedly attached to a distal end of the syringe body at the attachment surface; and a delivery mechanism comprising a plunger longitudinally formed to slidably fit within the bores of the syringe body and the incising shaft.
