Internal pedicle insulator apparatus and method of use
View Patent ↗Internal pedicle insulator apparatuses and methods are provided. A representative method includes: providing an internal pedicle insulator implant; inserting the implant into a pedicle such that the implant is positioned between a nerve and material that is to be applied in a vicinity of the nerve; applying the material in the vicinity of the nerve; and using the implant to prevent the material from contacting the nerve.
1. A method for using an internal pedicle insulator implant, comprising:
inserting a pedicle screw in a pedicle;
providing an internal pedicle insulator implant comprising a sheet having a first side for facing the pedicle screw and an opposing second side, the first side being shaped to complement an exterior shape of the pedicle screw;
after inserting the pedicle screw in the pedicle, inserting the internal pedicle insulator implant into the pedicle such that the internal pedicle insulator implant is positioned between a nerve and the pedicle screw, with the first side of the internal pedicle insulator implant being positioned adjacent to the pedicle screw;
applying material in the vicinity of the nerve through a fenestration in the pedicle screw such that the material is blocked from contacting the nerve by the internal pedicle insulator implant.
2. The method of claim 1 , wherein the internal pedicle insulator implant has a substantially rectangular shaped peripheral edge.
3. The method of claim 1 , further comprising:
providing an internal pedicle insulator apparatus having:
an outer insertion rod having an upper end and an opposing lower end; and
an inner insertion rod having a top end and a bottom end, the inner insertion rod being axially slidably engaged inside the outer insertion rod;
movably engaging the internal pedicle insulator implant with the inner insertion rod; and
sliding the outer insertion rod along the inner insertion rod toward the internal pedicle insulator implant such that the internal pedicle insulator implant moves along the inner insertion rod.
4. The method of claim 1 , wherein:
the internal pedicle insulator implant is tubular, with the first side being an interior surface of the internal pedicle insulator implant and the second side being an exterior surface of the internal pedicle insulator implant; and
in inserting the internal pedicle insulator implant, the internal pedicle insulator implant is inserted about the pedicle screw such that at least a portion of the pedicle screw extends into the interior of the implant.
5. The method of claim 4 , wherein the internal pedicle insulator implant has a first anti-rotation fin protruding outwardly from the second surface.
6. The method of claim 1 , wherein the internal pedicle insulator implant is curved about a longitudinal axis.
7. The method of claim 1 , wherein the material is a biological substance.
