Pain abatement catheter system

InactiveUS7022109B1Increase the areaSafely advancedInfusion syringesSurgical needlesEpidural spaceDevice breakage
A pain abatement catheter system particularly suited for treatment within the epidural space of a patient which includes an epidural introducer assembly, an epidural catheter and a steerable epidural guidewire assembly. The introducer assembly provides a one-piece introduction into the epidural space and includes an elongated introducer needle, an inner stylet, and a flexible outer sheath with a hub. The improved epidural catheter may be safely introduced into the epidural space under fluoroscopic guidance and can be effectively steered through tortuous anatomy, adhesions, or scar tissue for the purpose of delivering medications or contrast dyes to highly selective areas of the epidural space including nerve-root-sleeve injections. The epidural catheter/hub assembly is advanced over a soft atraumatic tip guidewire which significantly decreases the risk of device breakage, nerve root damage, or spinal cord injury. The improved catheter also increases efficacy, maneuverability, and safety in the diagnosis and intervening treatment of acute and chronic back and limb pain. The steerable epidural guidewire assembly allows for safely introducing a guidewire into the epidural space through a flexible sheath cannula and effectively maneuvering the catheter into highly specific areas while reducing the risk of epidural, nerve root, or spinal cord injury.
