A support device for supporting a wire includes a first support portion. A second support portion includes a first leg portion and a second leg portion that extends linearly and is attached to the first leg portion and to the first support portion. A third support portion includes a third leg portion having a third inwardly facing surface, which faces towards the third axial opening, and a third outwardly facing surface, which does not face towards the third axial opening. The third inwardly facing surface and the third outwardly facing surface have a different surface roughness. A fourth leg portion has a fourth inwardly facing surface, which faces towards the fourth axial opening, and a fourth outwardly facing surface, which does not face towards the fourth axial opening. The fourth inwardly facing surface and the fourth outwardly facing surface have a same surface roughness.

A feedthrough assembly includes: a ferrule; an insulating structure; and a seal fixedly securing the insulating structure within the ferrule, the seal comprising a glass and single-phase particulate dispersed therein; wherein the glass includes: 25% to 40% B.sub.2O.sub.3; 0 to 25% CaO; 0 to 25% MgO; 0 to 25% SrO; 0 to 10% La.sub.2O.sub.3; 5% to 15% SiO.sub.2; and 10% to 20% Al.sub.2O.sub.3; wherein all percentages are mole percentages of the glass.

The present invention relates to a feedthrough (200) adapted for use within a passage (300). The feedthrough (300) has a body (202) having a first interface region (204) and a second interface region (206). The first interface region (204) comprises a platform region (214). At least one electrical conductor (212) extends through the body (202) and out of the body (202) to both the first interface region (204) and the second interface region (206). A printed circuit board (216) is attached to the platform region (214). At least one pin hole (234) defined by the printed circuit board (216) is configured to accept the at least one electrical conductor (212).
