Abstract
A fluid delivery device is provided for delivering fluid to a target site such as an intervertebral disc during discography. The fluid delivery device includes pressure and volume sensors to determine the pressure and the volume of the fluid delivered to the intervertebral disc. The fluid delivery device is hand-held during use and includes a syringe assembly having a plunger with threads that enables controlled discharge of the fluid from the fluid delivery device by rotating the plunger in a housing of the fluid delivery device. The fluid delivery device may also include a communication module to wirelessly transfer data to an external device outside of a sterile field, while the fluid delivery device is in the sterile field. The fluid delivery device may also include a physiological sensor to monitor involuntary pain responses based on changing physiological parameters such as increases in body temperature or blood pressure.
