Systems, Devices, and Methods for Transpedicular Spinal Treatment

A transpedicular spinal treatment system, comprising:

• an insertion tool comprising an internal passage;
• and
• a vertebral body access port configured to couple to said insertion tool, said vertebral body access port comprising:
• a radiopaque tubular body having a central longitudinal axis and a sidewall extending along said longitudinal axis, the tubular body including a distal portion and a proximal portion interconnected by a central portion having an outer diameter and defining a working lumen having a first diameter;
• said distal portion having a distal tip and defining an access window opening extending through said sidewall, the working lumen terminating into a deflection surface formed in the distal portion adjacent the access window, the distal portion further including a radiographic orientation indicator configured to provide radiographic indication of an axial orientation of said access window about said longitudinal axis;
• said central portion defining a bone engaging structure on said sidewall to inhibit axial movement of the tubular body along the longitudinal axis, the sidewall being closed along a longitudinal length of said central portion;
• and
• said proximal portion having an enlarged head defining a tool engagement surface for connecting with said insertion tool and said internal passage communicating with said working lumen, said internal passage having a dimension that is equal to or larger than said first diameter, said tool engagement surface having a dimension that is larger than said first diameter, the tool engagement surface further including an alignment feature configured to permit engagement of the insertion tool in a fixed axial orientation relative to the tubular body.

A method comprising:

• inserting a vertebral body access port at an insertion location on a bone, said vertebral body access port comprising:
• a radiopaque tubular body having a central longitudinal axis and a sidewall extending along said longitudinal axis, the tubular body including a distal portion and a proximal portion interconnected by a central portion having an outer diameter and defining a working lumen having a first diameter;
• said distal portion having a distal tip and defining an access window opening extending through said sidewall, the working lumen terminating into a deflection surface formed in the distal portion adjacent the access window, the distal portion further including a radiographic orientation indicator configured to provide radiographic indication of an axial orientation of said access window about said longitudinal axis;
• said central portion defining a bone engaging structure on said sidewall to inhibit axial movement of the tubular body along the longitudinal axis, the sidewall being closed along a longitudinal length of said central portion;
• and
• said proximal portion having an enlarged head defining a tool engagement surface for connecting with an insertion tool and an internal passage communicating with said working lumen, said internal passage having a dimension that is equal to or larger than said first diameter, said tool engagement surface having a dimension that is larger than said first diameter, the tool engagement surface further including an alignment feature configured to permit engagement of the insertion tool in a predefined axial orientation relative to the tubular body
• orienting said access window to face in a fixed direction based on an orientation of said radiographic orientation indicator;
• inserting an awl into the working lumen from a proximal opening of said vertebral body access port;
• and
• moving said awl into said deflection surface and at least partially out of said working lumen through said access window.
