Title
(EN) SYSTEM AND METHOD FOR TREATING CHRONIC PAIN
(FR) SYSTÈME ET MÉTHODE DE TRAITEMENT DE LA DOULEUR CHRONIQUE
Abstract
(EN) Embodiments of a method for treating a patient suffering from chronic pain are described. A source location of chronic pain in a patient is first identified. A regional anaesthetic is then used to temporarily block selected nerves to confirm the source location and identify a target nerve. An electrode array of a neuromodulation apparatus is then implanted in the patient over the target nerve, such as just under the stratum corneum, and the neuromodulation apparatus is then used to stimulate the electrode array to create a long term conduction block that provides persistent pain relief to the patient.
(FR) Des modes de réalisation d'une méthode de traitement d'un patient souffrant de douleurs chroniques sont décrits. Un emplacement source de douleur chronique chez un patient est d'abord identifié. Une anesthésie locale est ensuite utilisée pour bloquer temporairement des nerfs sélectionnés pour confirmer l'emplacement source et identifier un nerf cible. Un réseau d'électrodes d'un appareil de neuromodulation est ensuite implanté sur le nerf cible du patient, juste sous la couche cornée, et l'appareil de neuromodulation est ensuite utilisé pour stimuler le réseau d'électrodes pour créer un bloc de conduction à long terme qui produit un soulagement persistant de la douleur chez le patient.
