Disclosed is a modular system for providing electrical stimulation to a patient's body, in which a first modular electrode section has a contoured back end configured to engage with a contoured front end of another electrode section or a tool that may be used to place the first modular electrode section in the patient's body. The contours of the back end of the first modular electrode section and of the front end of the second electrode section or tool allow the two components to engage with one another so as to prevent their separation in the horizontal plane (i.e., the plane that contains the top surfaces of the two components). Additionally, in order to prohibit both the lateral and vertical separation of the two components, a lead extending from the first modular electrode is configured to engage keels on the top surface of the second electrode portion or tool, with such keels providing a snap-type attachment between the lead and the second electrode portion or tool, such that the two components may be joined together but easily separated from one another through the intentional separation of the lead from the keels on the second electrode portion or tool. With this construction, a surgeon may ensure that the two components remain connected to one another through the implantation process, and may likewise separate the components if and when desired to accommodate a particular application or clinical condition.
