CA 2191345
An electrical bone growth promotion apparatus and method for the delivery of electrical current to an implant, surgically implanted within the intervertebral space between two adjacent vertebrae of the spine to promote bone growth, and the fusion process to areas adjacent to the implant, is disclosed. The apparatus of the present invention comprises a self-contained implant (10) having a surgically implantable, renewable power supply (60) and related control circuitry (70) for delivering electrical current directly to the implant (10), and thus directly to the area in which the promotion of bone growth is desired. The desired areas of bone growth promotion may be controlled by conducting negative charge only to the desired location of bone growth promotion.
Afin de favoriser la croissance osseuse par courant électrique, l'invention décrit un appareil et un procédé permettant d'acheminer un courant électrique vers un implant qui a été implanté de manière chirurgicale dans l'espace intervertébral entre deux vertèbres adjacentes de la colonne vertébrale, et cela afin de favoriser la croissance osseuse ainsi que le processus de fusion dans les zones adjacentes à l'implant. L'appareil de l'invention comprend un implant autonome (10) ayant une alimentation électrique renouvelable implantée de manière chirurgicale (60) ainsi qu'un circuit de commande associé (70) pour envoyer un courant électrique directement à l'implant (10) et donc directement à la zone où on désire favoriser la croissance osseuse. Les zones où l'on désire favoriser la croissance osseuse peuvent recevoir uniquement une charge négative.
