1. A device for delivering therapeutics to a target location in relation to a target site, the device comprising:
- an elongated hollow needle having a first end, a hollow shaft, and a second end, the first and the second ends forming openings and in communication along the hollow shaft of the elongated needle and the second end further defining a tip configured to allow insertion of the needle into a predetermined site;
a cannula that sits internally within the hollow shaft of the needle, the cannula configured to advance along the shaft of the needle and through the opening at the tip of the needle, wherein a distal end of the cannula exits the tip of the needle in a predetermined configuration; and
a catheter that sits internally within the cannula and is independently advanced in relation to the needle and cannula, the catheter capable of advancement through the pre-determined configuration at the distal end of the cannula and into the target location of the target site;
wherein the device, once positioned in the target location, is capable of delivering the biologic through the catheter to the target location in relation to the target site.

Abstract
Methods and device are provided for delivery of biologics to an intervertebral disc. Device described herein include a needle assembly and handle assembly that optimize biologic delivery parameters to a target location within a disc. The needle assembly includes the capability of advancing into the disc at pre-configured pathways that allow for minimized damaged and maximized positioning of the biologic.

12. A device for delivering biologics to a target location in an intervertebral disc, the device comprising:
-
a needle assembly having an elongated needle with a first end and a second end, the first and the second ends forming openings and in communication along the length of an elongated needle and the second end further defining a tip configured to allow insertion of the needle assembly into the intervertebral disc, and further comprising a cannula that sits internally within the elongated hollow needle, the cannula configured to advance along the length of the needle and through the opening at the tip of the needle in a pre-determined configuration; an adapter that operably attaches to the needle assembly, the adapter configured with a port for connection to the biologics, the adapter configured to reducing shearing force on the biologics once the biologics enter the adapter; wherein the device, once positioned in the intervertebral disc, is capable of delivering the biologic through the cannula of the needle assembly to the target location in the intervertebral disc. - View Dependent Claims (13)
