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-compatable 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 method of retrofitting a needle comprising:

acquiring an injection needle comprising a hollow cannula with an open distal end;

forming at least one side port in the hollow cannula proximate to the distal end so as to permit fluid communication between the inside and the outside of the hollow cannula via the side port; and

sealing the open distal end of the hollow cannula with a sealant so as to eliminate fluid communication between the inside and the outside of the hollow cannula via the distal end.

7. The method of claim 1, further comprising bending forceably the hollow cannula to impart a rigid bend proximate to the sealed distal end and the at least one side port.

8. The method of claim 1, further comprising mating and including at least one of a stylet with the retrofitted injection system, a wire with the retrofitted injection system, and an insulation with the retrofitted injection system.

2. The method of claim 2, wherein the injection needle comprises a beveled open distal end.

3. The method of claim 2, wherein the open distal end is sealed with a biocompatible material.

4. The method of claim 3, wherein the biocompatible material is a thermosetting polymer.

5. The method of claim 4, wherein the thermosetting polymer originates from an epoxy resin.

6. The method of claim 3, wherein the biocompatible material is at least one of a aliphatic polymer and a polyfluorocarbon.
