Modular antenna for implantable medical device

摘要

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.

主权项

1. An apparatus, comprising:
an implantable antenna assembly, comprising:
a dielectric core comprising:
first and second substantially parallel face portions, and a third face portion extending between the first and second face portions; anda cavity sized and shaped to accept an implantable lead connector;a spiral conductor extending along and conforming to the contours of the first, second, and third face portions on an exterior surface of the dielectric core, wherein the spiral conductor comprises a planar spiral pattern including concentric turns, wherein the planar spiral pattern is folded to form two or more planar portions including a planar portion located near, and substantially parallel to, the third face portion of the dielectric core, and wherein the spiral conductor extending along and conforming to the third face portion is configured to be positioned substantially opposite a connector assembly of an implantable medical device; andwherein the dielectric core and spiral conductor are configured to be at least partially contained within a dielectric compartment; andwherein 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.
