1. A feedthrough device comprising:
a body having longitudinally spaced first and second end faces and an inner surface defining an opening extending longitudinally through the body;
a conductor extending within the opening of the body; and
an insulator extending within the opening of the body transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body;
wherein the body has:
a first annular indentation formed longitudinally into one longitudinal end face and a second annular indentation formed longitudinally into the other longitudinal end face;
a first annular bulge formed in the inner surface of the body and longitudinally corresponding to the first annular indentation, the first annular bulge extending transversely of the body opening such that the first annular bulge crimps the insulator and the conductor; and
a second annular bulge formed in the inner surface of the body and longitudinally corresponding to the second annular indentation, the second annular bulge extending transversely of the body opening such that the second annular bulge further crimps the insulator and the conductor.
