Header core fixation design for an IMD
Aspects of the present disclosure are directed toward apparatuses, systems, and methods that may comprise a medical device having a header, a core assembly, and a scaffold assembly. The scaffold assembly may be configured to interface with the core assembly and position and support one or more circuit component relative to one or more other circuit components.
1. An implantable medical device comprising:
a core assembly comprising a core assembly housing enclosing integrated circuitry, the core assembly housing comprising a first end and a second end; and
a header coupled to the first end of the core assembly housing, the header comprising:
a first end coupled to the first end of the core assembly housing;
a second end;
an exterior surface having a first side, a second, opposite side, and an edge disposed between the first side and the second side, wherein the edge, at the second end, is curved in a direction away from the first end of the header;
an electrode disposed within the header, adjacent the first side of the exterior surface of the header, the electrode comprising a face disposed in a first plane; and
an antenna disposed within the header,
wherein a curved portion of the antenna is curved in the direction away from the first end of the header, is disposed in a second plane, and at least partially circumferentially surrounds the electrode, wherein the first plane and the second plane are different and parallel,
wherein the curved portion of the antenna is disposed closer to the curved edge of the second end of the header than any part of the electrode such that a distance between the position of the curved portion of the antenna and the second end of the header is shorter than a distance between the position of the electrode and the second end of the header,
wherein the curved portion of the antenna circumferentially surrounds an exterior portion of the electrode.
2. The medical device of claim 1 , wherein the first plane is parallel to the first side of the exterior surface of the header.
3. The medical device of claim 1 , wherein the first plane is parallel to the second plane.
4. The medical device of claim 1 , wherein the first side of the exterior surface of the header is disposed in the first plane.
5. The medical device of claim 1 , wherein the electrode comprises a generally rectangular shape.
6. The medical device of claim 1 , wherein the electrode comprises a clip that extends in a direction at least partially away from the first side of the exterior surface of the header.
7. The medical device of claim 1 , wherein the curve of the curved portion of the antenna corresponds to the curve of the curved second end of the edge of the header.
8. The medical device of claim 1 , further comprising a scaffold assembly arranged within the header and configured to interface with the core assembly and position and support the antenna relative to the electrode.
9. The medical device of claim 8 , wherein the first end of the core assembly comprises a first mating feature, and the scaffold assembly comprises a second mating feature, and the first mating feature is complimentary to the second mating feature.
10. A system comprising:
a medical device, configured to be implanted within a body of a patient, the medical device comprising:
a core assembly having a first end and a second end;
a header coupled, at a first end of the header, to the first end of the core assembly, the header having a second end opposite the first end thereof;
an antenna arranged within the header and configured to communicate data, the antenna comprising a semi-circular curved section that is curved in a direction away from the first end of the header; and
an electrode arranged within the header and configured to collect data, the electrode comprising a face disposed in a first plane, and wherein a portion of the antenna is disposed in a second plane, wherein the semi-circular curved section of the antenna is disposed closer to the second end of the header than any part of the electrode; and
a receiving device configured to receive the data communicated from the implantable medical device.
11. The system of claim 10 , wherein the implantable medical device comprises at least one of an implantable diagnostic monitor (IDM), a cardiac pacemaker, an implantable cardioverter defibrillator (ICD) device, and a cardiac resynchronization therapy (CRT) device.
12. The system of claim 10 , wherein the first plane is parallel to a first side of an exterior surface of the header.
13. The system of claim 12 , wherein the first side of the exterior surface of the header is disposed in the first plane.
14. The system of claim 12 , wherein the electrode comprises a clip that extends in a direction at least partially away from the first side of the exterior surface of the header.
