Abstract

A safety neural injection system includes at least a partially hollow cannula having an inside diameter, an outside diameter, a first length, a side port located coaxially along the hollow cannula for fluid communication between the inside and the outside of the hollow cannula, and an open distal end. The safety neural injection system also includes a flexible stylet with a shaped tip. The flexible stylet is capable of being releasably locked in a position within the hollow cannula and extends at least the first length of the hollow cannula. The hollow cannula proximate to the distal end includes a rigid bend so as to facilitate placement of the distal end at the treatment site.

Claims

1. A safety neural injection system comprising:

an at least partially hollow cannula being defined by a first inside diameter, a first outside diameter, a first length, and an opening at the distalmost tip of the at least partially hollow cannula in fluid communication with the inside and the outside of the at least partially hollow cannula;

a side port located coaxially along the at least partially hollow cannula in fluid communication between the inside and the outside of the at least partially hollow cannula, the side port being separate and spaced from the opening at the distalmost tip of the at least partially hollow cannula along a longitudinal axis of the at least partially hollow cannula; and

a flexible stylet with a shaped tip, wherein the flexible stylet is configured to be fixedly connected within the at least partially hollow cannula and to extend at least the first length of the at least partially hollow cannula;

wherein the at least partially hollow cannula proximate to the distalmost tip includes a rigid bend configured to facilitate placement of the distal end at a target site, wherein the flexible stylet is configured to elastically deform from an initial shape to a shape conforming to the rigid bend of the at least partially hollow cannula when the flexible stylet is inserted into the at least partially hollow cannula.

2. The system of claim 1, wherein the shaped tip is configured so as to form a flat plane across the open located at the distalmost tip of the at least partially hollow cannula.

3. The system of claim 1, further comprising an agent selected from the group consisting of a therapeutic agent, a diagnostic agent and a prophylactic agent.

4. The system of claim 3, wherein said therapeutic agent is anesthesia.

5. The system of claim 1, further comprising at least one of a connector, a wire, an insulation, or a probe.

6. The system of claim 1, further comprising a wire, wherein the wire is connected about a connector with an instrument.

7. The system of claim 6, wherein said connector is a plug and use connector.

8. The system of claim 1, wherein the stylet further comprises a side port.

9. A method for the administration of an agent with the safety neural injection system of claim 1 comprising:

locating a target site for administration;

adjusting the safety neural injection system to position the safety neural injection system relative to said site;

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

maneuvering the safety neural injection system using the rigid bend proximate to the distal end to facilitate placement of said safety neural injection system at said target site; and

administering said agent.

10. The method of claim 9, further comprising selecting the agent from the group consisting of a therapeutic agent, a diagnostic agent and a prophylactic agent.

11. The method of claim 9, further comprising selecting the therapeutic agent to comprise anesthesia.

12. The method of claim 9, further comprising utilizing the agent for stimulating a tissue about the site.

13. The method of claim 12, wherein stimulating the tissue comprises ablating at least a portion of the tissue.

14. The method of claim 9, wherein maneuvering the distal end is performed using a real-time imaging device.

15. The method of claim 9, further comprising determining the exact location of the distal end at the target site utilizing interaction between the safety neural injection system and a real-time imaging device.

16. The method of claim 9, further comprising selecting the target site from a group consisting of the digestive system, the circulatory system, nervous system, muscular system, skeletal system, respiratory system, urinary system, reproductive system, excretory system, endocrine system, and immune system of the human body.

17. A kit comprising the safety neural injection system of claim 1 and an agent to be administered.

18. The kit of claim 17, wherein said agent is selected from a group consisting of a therapeutic agent, a diagnostic agent and a prophylactic agent.

19. A safety neural injection system comprising:

an at least partially hollow cannula comprising;

a distal opening at the distal end of the at least partially hollow cannula in fluid communication with the inside and the outside of the at least partially hollow cannula;

a rigid bend located proximate to the distal end configured to facilitate placement of the distal end at a target site; and

a side port located coaxially along the at least partially hollow cannula in fluid communication between the inside and the outside of the at least partially hollow cannula, the side port being spaced from the distal opening at the distal end of the at least partially hollow cannula along a longitudinal axis of the at least partially hollow cannula; and

a flexible stylet with a shaped tip, wherein the flexible stylet is configured to be fixedly connected within the at least partially hollow cannula and to extend at least a length of the at least partially hollow cannula.

20. A safety neural injection system comprising:

an at least partially hollow cannula comprising;

a distal opening at the distal end of the at least partially hollow cannula in fluid communication with the inside and the outside of the at least partially hollow cannula;

a rigid bend located at a distal portion of the at least partially hollow cannula configured to facilitate placement of the distal end at a target site; and

a side port located coaxially along the at least partially hollow cannula at the distal portion of the at least partially hollow cannula in fluid communication between the inside and the outside of the at least partially hollow cannula, the side port being spaced from the distal opening at the distal end of the at least partially hollow cannula; and

a flexible stylet with a tip, wherein the flexible stylet is configured to be fixedly connected within the at least partially hollow cannula and to extend at least to the distal opening of the at least partially hollow cannula.
