Patent ID: 8364268

Claim:
An implantable signal generator comprising: a housing; a connector block having a first surface and a second surface; electronic circuitry contained within the housing; a power source contained within the housing; a lumen extending through the connector block from the first surface to the second surface, wherein the lumen has a length from the first surface to the second surface, wherein the lumen is configured to receive at least one lead, wherein said lead comprises at least one electrode connector; a plurality of contacts within the lumen, wherein the plurality of contacts are operably coupled to the electronic circuitry; and a non-transitory computer readable medium containing instructions for carrying out a process to determine at least one piece of information regarding a lead that is received within the lumen, the process comprising the steps of: measuring at least one characteristic of at least one of the plurality of contacts; and determining which of two ranges the measured characteristic fits, wherein the two ranges of characteristics correspond to an electrode connector being electrically coupled with the at least one of the plurality of contacts, and an electrode connector not being electrically coupled with the at least one of the plurality of contacts; and wherein the range which the measured characteristic fits is used in determining the at least one piece of information regarding the lead.
