ABSTRACT:
An epidural catheter with a patient end that forms a coil in its natural state, either in the plane of the length of the catheter or helically, so that, when inserted in the epidural space, the coil projects into the epidural space to ensure adequate retention but still ensuring that anaesthetic fluid emerges from side openings in the coil close to the point of insertion.
