1. A patient therapy system, comprising:

  • an implantable pulse generator having a computer-readable medium, wherein the pulse generator is electrically coupleable to a signal delivery device to form an electrical circuit that includes an electrical contact carried by the signal delivery device, and wherein the computer-readable medium contains instructions that, when executed,(a) determine an impedance of the electrical circuit, and(b) in response to a decrease in the impedance, automatically adjust a therapy signal parameter in accordance with which an electrical signal is delivered via the electrical contact.
