Title
(EN) MODULAR ANTENNA FOR IMPLANTABLE MEDICAL DEVICE
(FR) ANTENNE MODULAIRE POUR DISPOSITIF MÉDICAL IMPLANTABLE
Abstract
(EN)
Subject matter such as a method or apparatus can include an implantable antenna assembly, comprising a dielectric shell including first and second substantially parallel outer face portions, and a third outer face portion extending between the first and second portions, a spiral conductor extending along the first, second, and third portions on a surface of the dielectric shell. The dielectric shell and spiral conductor can be configured to be mechanically attached to a dielectric compartment, such as configured to be coupled to a housing of an implantable medical device. In an example, the implantable antenna assembly is configured to be electrically coupled to an implantable telemetry circuit configured to wirelessly transfer information electromagnetically using the implantable telemetry antenna, such as included as a portion of an implantable medical device.
(FR)
Cette invention concerne un procédé ou un appareil comportant éventuellement une antenne implantable, contenant une coque diélectrique constituée d'une première face externe et d'une deuxième face externe sensiblement parallèles, et d'une troisième face externe située entre la première face et la deuxième face, et une bobine conductrice située le long de la première face, de la deuxième face et de la troisième face sur une surface de la coque diélectrique. La coque diélectrique et la bobine conductrice peuvent être conçues pour être fixées mécaniquement à un compartiment diélectrique, et être par exemple couplées au boîtier d'un dispositif médical implantable. Dans un exemple, l'antenne implantable est conçue pour être couplée électriquement à un circuit de télémétrie implantable configuré pour transférer des données sans fil sous forme électromagnétique par le biais de l'antenne de télémétrie implantable, ladite antenne pouvant être considérée comme une partie d'un dispositif médical implantable.
