CA 2538569

Medical devices implanted in a patient can be activated and powered by an RF signal. Unless the medical device is properly oriented with respect to the transmitting antennas enough signal energy may not be received to power that device. However, optimum orientation can not be assured due to constraints on the implantation position. The present transmitting antenna is flat and omnidirectional thereby eliminating the need to properly orient the implanted medical device.

La présente invention a trait à des dispositifs médicaux implantés chez un patient pouvant être activés et alimentés par un signal radiofréquence. Si le dispositif médical ne présente pas une orientation correcte par rapport aux antennes de transmission une énergie de signal suffisante ne peut être obtenue pour l'alimentation de ce dispositif. Cependant, une orientation optimale ne peut être réalisée en raison de contraintes sur la position d'implantation. L'antenne de transmission de la présente invention est plane et omnidirectionnelle et permet donc d'éliminer la nécessité d'une orientation correcte du dispositif médical implanté.
