摘要: Apparatus and method provide flexibility generating a stimulation waveform (1901) to an electrode (2605-2619, 2621-2635) of an Implantable Neuro Stimulator (INS) (14). The stimulation waveform is synthesized for each rate period interval (1902). Each rate period interval is partitioned into time intervals (1905-1921), during which stimulation pulses (1923), recharging (1919), and time duration delays (1905, 1911) may be induced. With the embodiment of the invention, a second stimulation pulse (1925), having different electrical characteristics than a first stimulation pulse, may be generated during the rate period interval. An embodiment utilizes apparatus comprising a waveform controller (1001) and a waveform generator (1003) that are controlled by the waveform controller. The waveform controller uses waveform parameters to instruct the waveform generator to form stimulation pulses. Any of the components may be adjusted or deleted in the generation of the stimulation waveform. The embodiment enables any of the associated waveform parameters to be updated at the waveform controller in order to alter the stimulation waveform.

摘要: A first electrical signal and a second electrical signal are transmitted to one or more implanted leads including first and second electrodes, respectively. The first and second signals have a difference in frequency such that the combined potentials induce action potentials in a certain locus of electrically excitable tissue. Means are provided for adjusting the frequency difference, as well as the amplitudes of the signals so that the locus is altered.

摘要: Nouvel émetteur-récepteur amélioré et entièrement monolithique fabriqué sur une seule puce de semiconducteur et alimenté en courant continu à 5 volts. Cet émetteur-récepteur répond à toutes les exigences de l'émetteur-récepteur MIL-STD-1553 en ce qui concerne la largeur de l'impulsion et la temporisation, et peut fonctionner à une vitesse élevée de commutation et à une intensité élevée de courant de sortie pour générer des signaux TX OUT et TX OUT à deux états utilisés pour commander, respectivement, les deux enroulements primaires à prise médiane d'un transformateur de sortie. L'émetteur comprend deux voies de transmission de données à commande dynamique qui sont déphasées de façon régulée de sorte que l'une des voies de transmission soit entièrement coupée avant que l'autre ne se débloque, ce qui maximise le transfert d'énergie et l'efficacité de fonctionnement tout en minimisant le courant absorbé inutilement et en éliminant l'apparition de pointes de courant dans la sortie de l'émetteur. Le récepteur dudit émetteur-récepteur comprend un amplificateur différentiel raccordé pour commander d'abord un filtre différentiel équilibré puis un comparateur différentiel de fenêtres établissant la largeur de bande, les seuils de tension, la caractéristique de gain en fonction de la fréquence, et le point Q de l'émetteur-récepteur. De préférence, cette configuration entièrement monolithique utilise la technologie des condensateurs MOS et celle des alliages chrome-silicium pour former, respectivement, des condensateurs et résistances à couches minces à la surface de la puce monolithique, et s'utilise pour la construction de réseaux de filtrage RC, de résistances de polarisation et de charge, ou analogue. Ledit comparateur différentiel de fenêtres est raccordé à une paire d'étages logiques de sortie afin de générer à partir de ceux-ci des signaux de sortie RX DATA OUT et RX DATA OUT à deux états utilisés pour commander un ordinateur associé.

摘要: The present invention takes teh form of a current limiting apparatus and method for limiting current flow, induced whin thelevel of an external signal is greater than an external signal threshold signal level, in a conductive loop formed by a medical device implanted within living orgaism having electrically excitable tissue. The system includes an implantable pulse generator (IPG) system having a housing, sa signal generator disposed int he housing that generates an electrical signal, and at least one lead extending from the housing to convey electrical signal to the patient. To limit the induced current flow, the IPG includes current limiting componentry, an imedance increasing element, and/or alternating curretn blocking elements. These components provide an alternating current impedance path to the electrical ground from a lead coupled to the capacitive element. Also disclosed are techniques for reducing the effective surface area of the current inducing loop caused bz the IPG system.
