Antenna and attachment method for rechargeable implantable medical device

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;
• and
• 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 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.

A method for providing an implantable medical device, comprising:

• assembling a device housing having electronic components therein;
• joining a feedthrough assembly to the device housing;
• providing an 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 outer conductor and the dielectric material are concentrically arranged relative to one another about a longitudinal axis to form a tubular coaxial structure;
• and
• assembling a header body that embeds the antenna assembly therein to the device housing and enclosing the antenna assembly and feedthrough assembly.
