Patent

CA 2404354

The invention relates to medical technology, in particular to implanted and programmable electrostimulators for organs and tissues of an organism. The inventive implanted and programmable stimulator comprises an autonomous power supply unit, an analog-to-digital converter of signals emitted by biosensors (3a and 3b), a programmable block for forming an output pulse arranged in a body (1), a wire-electrode (2) placed outside the body (1) and used for pulsing the organs and tissues. According to the invention, said electrostimulator comprises a radio-frequency unit for communicating with an external programming and power supplying device (5) and placed inside the body (1), biosensors (3a) controlling a respiratory output and biosensors (3b) for controlling a cardiovascular output mounted on a shell covering the body (1) and the wire-electrode (2). The inventive electrostimulator can be powered by the autonomous unit and by the external programming and power supplying device (5).

L'électrostimulateur implantable programmable contient à l'intérieur de son boîtier (1): une unité d'alimentation indépendante, un convertisseur analogique / numérique des signaux provenant des biocapteurs (3a, 3b) et une unité programmable de génération d'impulsions de sortie; à l'extérieur du boîtier (1), il comprend un fil / électrode (2) servant à communiquer les impulsions de stimulation aux tissus et organes. Selon l'invention, l'électrostimulateur contient à l'intérieur de son boîtier (1) une unité de communication par radiofréquences avec un dispositif externe de programmation et d'alimentation (5) ainsi que des biocapteurs (3a) qui surveillent l'état fonctionnel du système respiratoire et des biocapteurs (3b) de l'état fonctionnel du système cardio-vasculaire. L'alimentation du biostimulateur peut s'effectuer à l'aide d'une unité d'alimentation autonome et d'un dispositif externe de programmation et d'alimentation (5).
