| titleOfInvention | Medical delivery device and method for delivering therapeutic agents directly into the annulus fibrosus of an intervertebral disc |
| abstract | A device for delivering a therapeutic agent to the disc of the spine includes an introducer needle having a hollow cannula (508), a stylet and a delivery catheter with a hollow shaft The catheter fits coaxially through the introducer needle when the stylet is removed. The catheter is longer than the introducer needle and has a blunt closed- ended tip (804) and at least one side port (812) at the distal end. The introducer needle and stylet have a sharpness and consistency that allows them to penetrate the wall of the annulus fibrosus. The catheter forms a pre-set bend (806) as it exits coaxially through the distal end of the introducer needle. The angle of the bend of the catheter in combination with the blunt tip allow the catheter to traverse inside the circumference of the annulus fibrosus without entering the nucleus pulposus or exiting the annulus fibrosus into surrounding tissue. |
