Abstract

Various embodiments may include methods of manufacture of a retrofitted neural injection system. Various embodiments may include acquiring an injection needle comprising a hollow cannula with an open distal end. Then, forming an at least one side port in the hollow cannula proximate to the distal end. Then, sealing the open distal end of the hollow cannula with a bio-compatible sealant so as to eliminate fluid communication between the inside and the outside of the hollow cannula via the distal end. In some embodiments, the bio-compatible sealant may be comprised of a thermosetting material. In some embodiments, the bio-compatible sealant may be comprised of a cured epoxy resin. In some embodiments, the bio-compatible sealant may be comprised of an aliphatic polymer. In some embodiments, the bio-compatible sealant may be comprised of an polyfluorocarbon.

Claims

1. A neural injection system comprising:

an at least partially hollow cannula with a sharp distal end, wherein said sharp distal end has a port comprising biocompatible sealant, wherein said port was formerly open;

wherein said hollow cannula is defined by a first inside diameter, a first outside diameter, a first length, and at least one side port in fluid communication between the inside and the outside of the hollow cannula;

wherein said side port is located coaxially at a predetermined distance from the distal end; and

wherein fluid communication between the inside and the outside of the hollow cannula via the distal end is eliminated by a hermetic seal.

2. The system of claim 1, wherein the neural injection system comprises a stylet.

3. The system of claim 2, wherein the stylet is releasably secured within a first portion of said hollow cannula.

4. The system of claim 2, wherein the stylet is fixedly secured within a first portion of said hollow cannula.

5. The system of claim 2, wherein the stylet is capable of sliding within said hollow cannula.

6. The system of claim 2, wherein the stylet extends up to the distal end of said first length of said hollow cannula.

7. The system of claim 2, wherein the stylet extends beyond the distal end of said first length of said hollow cannula.

8. The system of claim 2, wherein the stylet is hollow and has at least one side port.

9. The system of claim 8, wherein the side port of said stylet is in fluid communication with said side port of the hollow cannula.

10. The system of claim 9, wherein the neural injection system comprises a rigid bend in the hollow cannula proximate to the distal end.

11. The system of claim 10, further comprising an agent for delivery to said individual.

12. A method of treatment of an individual in need thereof comprising:

locating a site for treatment in said individual;

adjusting the neural injection system of claim 4 such that said system is positioned relative to said individual at a desired insertion point and orientation;

inserting at said site at least a portion of said neural injection system;

maneuvering the distal end of the neural injection system inside said individual proximate to the site; and

treating said individual.

13. A kit comprising the neural injection system of claim 4 and at least one agent.
