1. An insertion tool configured to facilitate insertion of an electrode array portion of a lead into a bodily orifice, the insertion tool comprising:

  • a handle assembly configured to facilitate handling of the insertion tool;

    a retractor assembly disposed at least partially within the handle assembly and comprising a stiffening member configured to be inserted into the electrode array portion and a spring-loaded retractor member coupled to the stiffening member, wherein the spring-loaded retractor member is configured to move from a distal position to a proximal position relative to the handle assembly to at least partially retract the stiffening member from the electrode array portion; and

    a slider assembly disposed at least partially within the handle assembly and configured to selectively retain the spring-loaded retractor member relative to the slider assembly, wherein the slider assembly is further configured to release the spring-loaded retractor member to move from the distal position to the proximal position relative to the handle assembly in response to an advancement by a user of the slider assembly in a distal direction relative to the handle assembly.
