Abstract

A novel neural injection system and related methods are herein disclosed. Various embodiments of an embodiment of a neural injection system of the present invention provide for at least one benefit of enhanced injection characteristics, increased operational efficiency, reduced cost per unit, reduced incidence of injury through intraneural/intravascular injection, reduced incidence of injury through pricking/piercing, and/or the like.

Claims

1. A method for administering a medicament to a patient comprising the steps of:

locating a site for injection;

inserting at least a portion of a neural injection system comprising

an at least partially hollow cannula being defined by a first inside diameter, a first outside diameter, and a first length,

a side port located coaxially along the lateral axis of the cannula for fluid communication from inside said at least partially hollow cannula to outside said at least partially hollow cannula, wherein said cannula has a rounded shoulder on an open blunt distal end;

a stylet, wherein the stylet is capable of being releasably locked in a first position within said cannula;

wherein the first position is characterized by the stylet being flush with a shoulder of the rounded open blunt distal end of said cannula;

wherein the stylet has an outside diameter that is smaller than the first inside diameter of the cannula; and

an introducer being defined by a second inside diameter, a second outside diameter, and a second length, wherein the second inside diameter is larger than the first inside diameter of the cannula; and

wherein the introducer is used for access across a tissue of a patient that cannot be punctured by the rounded shoulder on the open blunt distal end during a normal insertion procedure; and

injecting the medicament into the patient.

2. The method of claim 1, wherein injecting the medicament into the patient comprises causing a therapeutic amount of the medicament to ooze multidirectionally from a distal portion of the neural injection system into tissue of the patient.

3. The method of claim 1, further comprising preparing a patient for administering a medicament.

4. The method of claim 3, wherein preparing a patient for administration of a medicament comprises placing the patient'"'"'s head in a neutral position.

5. The method of claim 1, further comprising stimulating a tissue about the site.

6. The method of claim 5, wherein the step of stimulating said tissue comprises ablating at least a portion of said tissue.

7. The method of claim 1, further comprising the step of probing a tissue.

8. The method of claim 1, wherein the medicament is anesthesia.

9. The method of claim 1, wherein the medicament is injected into a particular tissue of the patient.

10. The method of claim 9, wherein the medicament is injected into an internal organ.

11. The method of claim 10, wherein the medicament is injected into a wall of a beating heart.

12. The method of claim 1, wherein the medicament is a therapeutic agent.

13. The method of claim 1, wherein the medicament is a nucleic acid.
