1. A lead fixation device for securing a portion of a lead relative to a surface of a skull, the lead fixation device comprising:
a skull attachment member having an upper surface and a lower surface; and
a compression mechanism integral with the skull attachment member and forming a passageway relative to the skull attachment member, which passageway is characterized by a slot that extends along a length of the passageway,
wherein the compression mechanism is configured to:
transition a width of the slot from an initial size to an expanded size that is greater than the initial size upon a receipt of appropriately directed first forces in a region of the compression mechanism that forms the passageway, and
transition the width of the slot from the initial size to a collapsed size upon a receipt of appropriately directed second forces in a region of the compression mechanism that forms the passageway.
