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, the hollow cannula being devoid of other structure within the hollow cannula, the open distal end exhibiting a bevel having a distalmost sharp end and a proximal heel end;
forming only one single side port in a sidewall of the hollow cannula proximate to the distal end so as to permit fluid communication between an inside and an outside of the hollow cannula via the one single side port, the remainder of the sidewall of the hollow cannula comprising an imperforate structure;
positioning the one single side port on a side of the needle that is radially aligned with the proximal heel end to enable a user to directionally inject a fluid therapy from only the one single side port;
disposing a mass of sealant within the hollow cannula while the hollow cannula is devoid of other structure to entirely eliminate fluid from exiting the hollow cannula via the distal end while still enabling fluid communication between the inside and the outside of the hollow cannula via the one single side port;
positioning the mass of sealant such that the mass of sealant does not hinder penetrating or leading operations of the distal end of the hollow cannula while not encumbering or blocking the one single side port;
solidifying the mass of sealant within the hollow cannula to form a solid mass of sealant; and
configuring the retrofitted needle with the mass of sealant disposed in the hollow cannula to ablate target tissue in a subject.

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 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 biocompatible sealant so as to eliminate fluid communication between an inside and an outside of the hollow cannula via the distal end. In some embodiments, the biocompatible sealant may be comprised of a thermosetting material. In some embodiments, the biocompatible sealant may be comprised of a cured epoxy resin. In some embodiments, the biocompatible sealant may be comprised of an aliphatic polymer. In some embodiments, the biocompatible sealant may be comprised of a polyfluorocarbon.

9. A method of forming a needle comprising:
-
defining one single side port in an at least partially hollow cannula of an injection needle to enable fluid communication between an inside and an outside of the at least partially hollow cannula through the one single side port; aligning the one single side port about a diameter of the at least partially hollow cannula with a heel of a beveled tip of the at least partially hollow cannula; and disposing a mass of sealant in the at least partially hollow cannula between the one single side port and an open distal end to block fluid communication between the one single side port and the open distal end while still enabling fluid communication between the inside and the outside of the at least partially hollow cannula via the one single side port. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of forming a needle comprising:
-
defining one single side port in an at least partially hollow cannula of an injection needle to enable fluid communication between an inside and an outside of the at least partially hollow cannula through the one single side port; disposing a flowable mass of material in the at least partially hollow cannula between the one single side port and an open distal end to at least partially prohibit fluid communication between the one single side port and the open distal end; at least partially solidifying the flowable mass of sealant. - View Dependent Claims (16, 17, 18, 19, 20)
