Abstract
Devices and methods are provided for an implantable medical device (IMD) comprising a device housing having electronic components therein, a feedthrough assembly joined to the device housing, an antenna assembly, and a header body mounted to the device housing and enclosing the antenna assembly and feedthrough assembly. The antenna assembly including an inner conductor, a dielectric material, and an outer conductor arranged to form a coaxial structure.
Claims11
An implantable medical device, comprising:
- a device housing having electronic components therein;
- a feedthrough assembly joined to the device housing;
- an antenna assembly;
- a header body mounted to the device housing and enclosing the antenna assembly and feedthrough assembly;
- the antenna assembly including an inner conductor, an outer conductor and a dielectric material disposed between the inner conductor and the outer conductor, wherein the inner conductor, the dielectric material and the outer conductor are concentrically arranged relative to one another about a longitudinal axis to form a tubular coaxial structure, and the dielectric material surrounds a perimeter of the inner conductor and the outer conductor surrounds a perimeter of the dielectric material;
- and
- the antenna assembly is formed with an ellipse shaped cross-section that includes a major portion and a minor portion, the major portion corresponding to the tubular coaxial structure formed of the inner and outer conductors and dielectric material.

An implantable medical device, comprising:
- a device housing having electronic components therein;
- a feedthrough assembly joined to the device housing, the feedthrough assembly including a feedthrough pin coupled to the electronic components within the device housing, the feedthrough pin having a distal end extending from the feedthrough assembly;
- an antenna assembly;
- a header body enclosing the antenna assembly;
- a pin receptacle mounted within the header body, the pin receptacle electrically coupled to the antenna assembly, the pin receptacle including a pin retention cavity therein, the pin receptacle including a proximal end that is open to the pin retention cavity, the feedthrough pin configured to be inserted into the pin retention cavity when the header body is mounted on the feedthrough assembly and the device housing;
- the pin receptacle including a spring mounted within the pin retention cavity, the spring configured to physically and electrically engage the feedthrough pin when inserted into the pin retention cavity;
- and
- the antenna assembly including an inner conductor, an outer conductor and a dielectric material disposed between the inner conductor and the outer conductor, wherein the inner conductor, the dielectric material and the outer conductor are concentrically arranged relative to one another to form a tubular coaxial structure having a longitudinal axis, the dielectric material surrounds a perimeter of the inner conductor and the outer conductor surrounds a perimeter of the dielectric material.
