Preformed wire routes

A medical device, comprising:

• a housing comprising a first connector block on a first surface of the housing, the first connector block comprising a first stub feedthrough pin extending normal from a surface of the first connector block and the first surface of the housing;
• a header comprising a lead port having a first electrical contact;
• and
• a first preformed wire having a proximate portion, a major portion, and a distal portion,
• wherein the proximate portion of the first preformed wire comprises a number of turns forming a lumen having a depth corresponding to the number of turns, wherein the number of turns that form the lumen is between 2 and 4 turns, wherein each turn has a height corresponding to the diameter of the preformed wire, wherein the number of turns comprises a first turn configured for placement over the first stub feedthrough pin and engagement of a base of the first stub feedthrough pin proximate the surface of the first connector block and a top turn opposite the lumen from the first turn and proximate the major portion of the first preformed wire, wherein the lumen is configured to engage and secure the proximate portion of the first preformed wire to the first stub feedthrough pin and raise the major portion of the first preformed wire over the first connector block and the first surface of the housing,
• wherein the first stub feedthrough pin has a length commensurate with the depth of the lumen, wherein the depth of the lumen is determined by the number of turns of the proximate portion of the first preformed wire, wherein the length of the first stub feedthrough pin is less than 5 diameters of the first preformed wire to not negatively impact the width of the header,
• wherein the major portion of the first preformed wire is pre-shaped prior to assembly to optimize routing the first preformed wire between the first stub feedthrough pin and the first electrical contact of the lead port of the header.
