Medical lead connection system

A system for implanting a medical electrical lead:

• an elongated lead body including a proximal portion, having a proximal end;
• a plurality of connector rings positioned about the proximal portion, the plurality of connector rings comprising a most proximal connector ring;
• a first insulative spacer positioned between the most proximal connector ring and the proximal end of the proximal portion of the lead body;
• a lead extension joined to a proximal end of the proximal portion of the lead body, the lead extension comprising a plurality of temporary contact surfaces, a plurality of conductors, and a severing section, the temporary contact surfaces electrically coupled to corresponding connector rings of the plurality of connector rings via corresponding conductors of the plurality of conductors, and the severing section including a visual marker and positioned in proximity to the proximal end of the proximal portion of the lead body;
• a generally tubular sleeve body forming a lumen for engaging the proximal portion of the lead body;
• a pin connector member positioned at a proximal end of the sleeve assembly and comprising an axial through bore and a proximal opening, the axial though bore substantially aligned with the lumen of the sleeve body;
• wherein
• the visual marker extends proximally from the proximal opening of the pin connector member when the lumen of the sleeve body engages the proximal portion of the lead body.
