1. A method for constructing an instrument with a covered bore for subcutaneous implantation, comprising:
- forming an incising body by forming a non-circular bore having a distal opening in an incising shaft, sharpening a cutting edge extending from a bottom distal end of the incising shaft beyond the distal opening of the non-circular bore, and affixing an attachment assembly at a top distal end of the incising shaft;
constructing a plunger sized to fit within the non-circular bore;
inserting the plunger in the non-circular bore of the incising body; and
affixing a cover to the attachment assembly, wherein the cover extends down to the bottom distal end and, when closed, the cover encloses the distal opening proximal to the cutting edge.

Abstract
A method for constructing an instrument with a covered bore for subcutaneous implantation is provided. An incising body is formed by defining a non-circular coaxial bore and sharpening a cutting edge extending from a bottom distal end beyond the opening of the coaxial bore and affixing an attachment point at a top distal end. A plunger is constructed sized to fit within the coaxial bore. The plunger is inserted in the bore of the incising body. A cover is affixed to the attachment point, wherein the cover extends down to the bottom distal end and, when closed, the cover encloses the opening proximal to the cutting edge.

6. A method for constructing an instrument with a captive plunger for subcutaneous implantation, comprising:
-
forming an incising body, comprising; forming a cavity comprising a cross-sectional size located along a longitudinal axis in an incising shaft, the incising shaft comprising a cutting edge extending from a bottom distal end beyond a distal opening of the cavity and an attachment point at a top distal end; and forming a syringe body defining a bore extending along the longitudinal axis and comprising a cross-sectional size smaller than the cross-sectional size of the cavity, the syringe body positioned on a proximal end of the incising shaft with the bore aligned with a portion of the cavity; constructing a plunger assembly comprising a plunger shaft sized to fit within the syringe body and affixed on one end to a plunger comprising a captive member that is sized to fit within the cavity; inserting the plunger assembly through an end of the incising body; and affixing a cover pivotally attached at the attachment point and extending down to the bottom distal end, wherein the cover, when closed, encloses the distal opening of the cavity proximal to the cutting edge. - View Dependent Claims (7, 8, 9, 10)

11. An implantation instrument assembly, comprising:
-
an incising body defining a non-circular bore and comprising a sharpened cutting edge extending from a bottom distal end beyond an opening of the non-circular bore and an attachment point at a top distal end; a plunger non-fixedly contained within the non-circular bore and sliding longitudinally therein; a cover pivotally attached at the attachment point and extending down to the bottom distal end, wherein the cover, when closed, encloses the opening proximal to the cutting edge; and an implant positioned within the bore. - View Dependent Claims (12, 13, 14)
