RETROFITTED NEURAL INJECTION SYSTEM AND RELATED METHODS
First Claim
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.

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.
