Implantable device for treating epilepsy and cardiac rhythm disorders
Various aspects relate to an implantable device. Various device embodiments comprise at least one pulse generator and a controller to communicate with the pulse generator(s). The pulse generator(s) is (are) adapted to deliver a first electrical signal through at least one electrode positioned proximate to a vagus nerve and to deliver a second electrical signal through at least one electrode positioned within or proximate to the heart. The controller includes a module to provide epilepsy therapy that includes delivering the first electrical signal though the at least one electrode proximate to the vagus nerve and a module to provide a cardiac rhythm management (CRM) therapy that includes delivering the second electrical signal through at least one electrode positioned within or proximate to the heart. The CRM therapy includes at least one therapy selected from an antitachycardia therapy and a cardiac resynchronization therapy (CRT). Other aspects and embodiments are provided herein.
