Title
(EN) SYSTEMS AND METHODS FOR TREATMENT OF DRY EYE
(FR) SYSTÈMES ET PROCÉDÉS POUR TRAITER LA SÉCHERESSE OCULAIRE
Abstract
(EN)
A stimulation system stimulates anatomical targets in a patient for treatment of dry eye. The stimulation system may include a controller and a microstimulator. The controller may be implemented externally to or internally within the microstimulator. In various embodiments, the components of the controller and microstimulator may be implemented in a single unit or in separate devices. When implemented separately, the controller and microstimulator may communicate wirelessly or via a wired connection. The microstimulator may generate pulses from a signal received from the controller and apply the signal via one or more electrodes to an anatomical target. In various embodiments, the microstimulator does not have any intelligence or logic to shape or modify a signal, but rather is a passive device configured to generate a pulse based on a signal received from the controller. In various embodiments, the microstimulator includes intelligence to shape or modify a signal.

La présente invention concerne un système de stimulation qui stimule des cibles anatomiques chez un patient pour le traitement de la sécheresse oculaire. Le système de stimulation peut comprendre un organe de commande et un microstimulateur. L'organe de commande peut être implémenté à l'extérieur ou à l'intérieur du microstimulateur. Dans divers modes de réalisation, les composants de l'organe de commande et du microstimulateur peuvent être implémentés dans une seule unité ou dans des dispositifs séparés. Lorsqu'ils sont implémentés séparément, l'organe de commande et le microstimulateur peuvent communiquer sans fil ou via une connexion câblée. Le microstimulateur peut produire des impulsions à partir d'un signal reçu depuis l'organe de commande et appliquer le signal à une cible anatomique par le biais d'une ou de plusieurs électrodes. Dans divers modes de réalisation, le microstimulateur ne possède ni intelligence ni logique pour mettre en forme ou modifier un signal, mais est plutôt un dispositif passif conçu pour générer une impulsion sur la base d'un signal reçu de l'organe de commande. Dans divers modes de réalisation, le microstimulateur comprend une intelligence pour mettre en forme ou modifier un signal. Dans divers modes de réalisation, des formes d'onde possédant des caractéristiques différentes de fréquence, d'amplitude et de période peuvent stimuler différentes cibles anatomiques chez un patient.
