Method of treatment delivery

A method for drilling into living bone comprising:

• providing a drill, said drill having a shaft, a cutting bit, a guide tube, and a drive unit, said shaft having a first end,
• said cutting bit located at said shaft first end, said cutting bit being ductile, and said cutting bit having width,
• said guide tube surrounding said shaft, said guide tube having a sharp non-coring tip at its end, said guide tube having an interior passage, and said guide tube having length,
• said drive unit operably connected to said shaft,
• applying said guide tube to the surface of said bone,
• at least partially rotating said shaft by operation of said drive unit;
• cutting said bone by said cutting bit;
• advancing said shaft and said bit into said bone;
• removing said drill from said guide tube;
• providing a cortex adapter,
• said cortex adapter having a first end, said cortex adapter sized to pass through said interior passage of said guide tube, said cortex adapter having length greater than said length of said guide tube, and said cortex adapter having an interior passage, said cortex adapter having an outer diameter at said first end of said cortex adapter, said outer diameter of said cortex adapter at said first end of said cortex adapter equivalent to but not greater than said width of said cutting bit;
• inserting said cortex adapter into said guide tube and into said tissue at said first end of said cortex adapter,
• providing a stylet,
• said stylet having length sufficient to pass through said cortex adapter;
• inserting said stylet into said cortex adapter;
• removing said stylet from said cortex adapter;
• and
• introducing a treatment to said living bone through said cortex adapter.
