Abstract
A solid stepped needle delivers a disc shunt bridging between muscle and a degenerated disc, drawing blood plasma from muscle into the degenerated disc to alleviate back pain and regenerate the disc. The device further includes pull lines attached to the ends of the disc shunt for withdrawing and repositioning the stepped needle during shunt delivery.
