Abstract

A compound needle comprising an outer needle shaft having an outer needle tip and an inner needle shaft having an inner needle tip wherein one of the needle tips is sharper than the other needle tip. The outer needle tip can be formed of a flexible material and/or have a flexible/movable connection to the outer shaft, which enables the inner needle tip to be deployed and/or refracted through the outer needle tip.

Claims

1-8. -8. (canceled)

9. A compound needle comprising:

an inner shaft having a first needle tip;

an outer shaft having a second needle tip;

wherein one of the first and second needle tips is sharper than the other of the first and second needle tips;

wherein the outer shaft has a hollow core and wherein the inner shaft is disposed within the hollow core; and

wherein the first needle tip of the inner shaft is deployable through the second needle tip of the outer shaft.

10. The compound needle of claim 9, wherein the first needle tip is a blunt tip and the second needle tip is a sharp tip and wherein the sharp tip is sharper than the blunt tip.

11. The compound needle of claim 10, wherein the sharp tip requires less force than the blunt tip to advance through human tissue.

12. The compound needle of claim 10, wherein the sharp tip further comprises perforating members.

13. The compound needle of claim 9, wherein the first needle tip is a sharp tip and the second needle tip is a blunt tip and wherein the sharp tip is sharper than the blunt tip.

14. The compound needle of claim 13, wherein the sharp tip is retractable through the blunt tip into the hollow core of the outer shaft.

15. The compound needle of claim 9, wherein the outer shaft includes additional features that improve the echogenicity of the compound needle.

16. The compound needle of claim 15, wherein the additional features comprise indentations on the outer shaft.

17. The compound needle of claim 15, wherein the additional features comprise protruding bumps of metallic deposits on the outer shaft.

18. The compound needle of claim 9, wherein the outer shaft has an electrically insulating layer formed on an exterior surface of the outer shaft.

19. A compound needle system comprising:

a compound needle, the compound needle comprising;

an inner shaft having a first needle tip;

an outer shaft having a second needle tip;

wherein one of the first and second needle tips is sharper than the other of the and second needle tips;

wherein the outer shaft has a hollow core and wherein the inner shaft is disposed within the hollow core; and

wherein the first needle tip of the inner shaft is deployable through the second needle tip of the outer shaft; and

a visual guidance instrument wherein the visual guidance instrument is used in combination with the compound needle to treat or locate a target, the

visual guidance instrument comprising;

an external monitor device; and

a handheld probe in communication with the external monitor device.

20. The compound needle system of claim 19 wherein the visual guidance instrument is an ultrasound device and wherein the handheld probe emits into the target ultrasonic waves that reflect off the compound needle.

21. The compound needle system of claim 19 further comprising a nerve stimulation instrument wherein the nerve stimulation instrument is used in combination with the compound needle to stimulate a target, the nerve stimulation instrument comprising:

a stimulation control device;

a grounding pad; and

wherein the stimulation control device is in electrical communication with the first needle tip of the inner shaft.

22. The compound needle system of claim 21, further comprising an insulating layer wherein the insulating layer is evenly placed on the outer needle shaft.

23. A method for treating a target using a compound needle system, the method comprising:

inserting a compound needle into the skin of a patient wherein the compound needle comprises;

an inner shaft having a first needle tip;

an outer shaft having a second needle tip;

wherein one of the first and second needle tips is sharper than the other of the first and second needle tips;

wherein the outer shaft has a hollow core and wherein the inner shaft is disposed within the hollow core; and

wherein the first needle tip of the inner shaft is deployable through the second needle of the outer shaft;

advancing the compound needle to a first position;

using a visual guidance instrument to visualize the first position wherein the

visual guidance instrument comprises;

an external monitor device;

a handheld probe; and

wherein the handheld probe is in communication with the external monitor device.

deploying the first needle tip of the inner shaft;

advancing the first needle tip of the inner shaft to a second position;

using the visual guidance instrument to confirm that the second position is a proper position; and

applying therapy to the target.

24. The method of claim 23, wherein the visual guidance instrument is an ultrasound device, and further comprising:

emitting into the target ultrasonic waves that reflect off the compound needle.

25. The method of claim 23, further comprising using a nerve stimulation instrument to stimulate the target.
