ABSTRACT:
An electrical stimulation catheter system particularly suited for treating the epidural space of a patient, which includes a multiple electrode stimulation catheter, a stiffening element for the catheter and a device for securing an implanted catheter to the patent. A catheter according to the invention includes first and second flexible electrodes defined respectively by a portion of the catheter body and second flexible element. Preferably, leads for each electrode are secured to slideable rings around the proximal end of the catheter to prevent entanglement and confusion of the leads. A catheter securing device according to the invention includes a resilient member having a bore within which the catheter is secured. Holes for suturing or adhesive coating are provided to secure the device, which also may serve as an external electrode, to the patient.
