Abstract

The invention comprises a method for introduction of materials into a patient'"'"'s body. The method generally comprises providing an elongate member for introducing the material. The elongate member defines a lumen and comprises a distal end defining an aperture and a proximal end. The method further comprises the steps of positioning the elongate member at a target site of a patient'"'"'s body; providing a motorized device at least partially disposed within the lumen; and introducing the material through the lumen into the target site using the motorized device.

Claims

1. A method for introducing material into a region of a patient'"'"'s body, comprising the steps of:

providing an elongate member for introducing the material, the elongate member defining a lumen and having a distal end defining an aperture and a proximal end operatively connected to a receptacle structured to house the material, the receptacle being at least partially pervious to light to allow visualization of the material within the receptacle;

positioning the elongate member at a target side of a patient'"'"'s body using fluoroscopic visualization;

providing a motorized device at least partially disposed within the lumen, the motorized device including a shaft and helical projections extending from the shaft, the motorized device being configured to rotate the shaft and helical projections in a forward and a reverse direction; and

introducing the material from the receptacle and through the lumen into the target site using the motorized device to rotate the shaft.

2. The method of claim 1, wherein the motorized device remains substantially static with respect to a longitudinal axis of the elongate member during the step of introducing material.

3. The method of claim 1, wherein the step of positioning the elongate member further comprises the steps of:

providing an introducer apparatus comprising a cannula defining a cannula lumen and an obturator disposed within the cannula lumen;

inserting the introducer apparatus into the patient'"'"'s body such that a distal end of the cannula is positioned at the target site of the patient'"'"'s body;

withdrawing the obturator from the cannula lumen; and

inserting the elongate member into the cannula lumen.

4. The method of claim 3, wherein the step of inserting the introducer apparatus in facilitated by fluoroscopic visualization.

5. The method of claim 3, further comprising a step of injecting a fluid through the cannula lumen.

6. The method of claim 5 wherein the fluid is selected from the group consisting of an anesthetic, an antibiotic and a dye.

7. The method of claim 3, wherein the distal end of the cannula is positioned at a posterior portion of a nucleus pulposus of an intervertebral disc of the patient'"'"'s body.

8. The method of claim 1, wherein the material is selected from the group consisting of synthetic materials, synthetic tissues, natural tissues, cements and pharmaceutical compounds.

9. The method of claim 1, wherein a distal end of the motorized device is recessed proximally from the aperture when the motorized device is fully disposed within the elongate member, wherein the recession of the distal end of the motorized device functions to reduce the likelihood of damage to non-target tissue.

10. The method of claim 1, wherein at least one of the elongate member and the motorized device are operatively connected to a handpiece and wherein a motor is housed within the handpiece and is operatively connected to the motorized device.

11. The method of claim 1, wherein a distal portion of the elongate member defines at least one slot extending proximally from a distal end of the elongate member.

12. The method of claim 1, wherein the receptacle is coaxial with the elongate member.

13. The method of claim 12, wherein the receptacle is coaxial with the shaft.

14. A method for introducing material into a region of a patient'"'"'s body, comprising the steps of:

providing an elongate member for introducing the material, the elongate member defining a lumen and having a distal end defining an aperture and a proximal end operatively connected to a receptacle structured to house the material, the receptacle being at least partially pervious to light to allow visualization of the material within the receptacle;

positioning the elongate member at a target side of a patient'"'"'s body;

providing a motorized device at least partially disposed within the lumen, the motorized device including a shaft and helical projections extending from the shaft;

introducing the material from the receptacle and through the lumen into the target site using the motorized device to rotate the shaft; and

removing at least one of the material, a second material and tissue from the target site.

15. The method of claim 14, wherein the tissue is tissue of a nucleus pulposus of an intervertebral disc.

16. A method for introducing material into a region of a patient'"'"'s body, comprising the steps of:

providing an elongate member for introducing the material, the elongate member defining a lumen and having a distal end defining an aperture and a proximal end operatively connected to a receptacle structured to house the material, the receptacle being at least partially pervious to light to allow visualization of the material within the receptacle;

positioning the elongate member at a target side of a patient'"'"'s body;

providing a motorized device at least partially disposed within the lumen, the motorized device including a motor and an auger with a shaft and helical projections extending from the shaft;

introducing the material from the receptacle and through the lumen into the target site using the motorized device to rotate the shaft, the motorized device being configured to rotate the auger in a forward and a reverse direction.

17. A device for introducing material into a target site of a patient'"'"'s body, the device comprising:

an elongate member defining a lumen and having a distal end defining an aperture and a proximal end;

a receptacle structured to house the material and operatively connected to the proximal end, the receptacle being at least partially pervious to light to allow visualization of the material within the receptacle; and

a motorized device at least partially disposed within the lumen, the motorized device including a shaft and helical projections extending from the shaft, the material being introducible from the receptacle and through the lumen into the target site using the motorized device to rotate the shaft in one direction, the motorized device rotating the shaft in another direction to remove material from the target site.

18. The device of claim 17, wherein the motorized device is fixedly mounted with respect to a longitudinal axis of the elongate member.

19. The device of claim 17, wherein a distal end of the motorized device is recessed proximally from the aperture when the motorized device is fully disposed within the elongate member.

20. The device of claim 17, wherein at least one of the elongate member and the motorized device are operatively connected to a handpiece and wherein a motor is housed within the handpiece and is operatively connected to the motorized device.

21. The device of claim 17, wherein the motorized device comprises an auger.

22. The device of claim 17, wherein the receptacle is coaxial with the elongate member.

23. The device of claim 22, wherein the receptacle is coaxial with the shaft.

24. A device for introducing material into a target site of a patient'"'"'s body, the device comprising:

an elongate member defining a lumen and having a distal end defining an aperture and a proximal end;

a receptacle structured to house the material and operatively connected to the proximal end, the receptacle being at least partially pervious to light to allow visualization of the material within the receptacle;

a motorized device at least partially disposed within the lumen, the motorized device including a shaft and helical projections extending from the shaft, the material being introducible from the receptacle and through the lumen into the target site using the motorized device to rotate the shaft; and
