    摘要： A medical device known as a trial neuro stimulator with a diagnostics module to determine whether the therapy lead is operational for delivering stimulation therapy to improve operation in areas such as reliability and patient comfort is disclosed. The trial neuro stimulator is typically used to test the efficacy of neuro stimulation before implanting an implantable neuro stimulator in a patient. The trial neuro stimulator has a processor, memory, system reset, telemetry module, recharge module, power management module, power source, therapy module, therapy measurement module, and diagnostics module. The diagnostics module can be a lead sensor, a software detector using therapy lead measurements from the therapy measurement module, or, a combination of both the lead sensor and software detector to detect whether the therapy lead is operational. A method for diagnosing whether a therapy lead is operational is also disclosed.

    摘要： A pulse stimulation system configured for implantation into a patient's body comprises a pulse stimulator, a conductive stimulation lead having a proximal end electrically coupled to the pulse simulator and having a distal end, and an electrode assembly coupled to the distal end of the stimulation lead. The electrode assembly comprises an electrode body having a therapy electrode thereon that is electrically coupled to the stimulation lead for delivering therapy to the patient. A floating electrode is configured to contact the patient's body tissue and has a surface area substantially larger than that of the therapy electrode. A filter is coupled between the therapy electrode and the floating electrode for diverting RF energy toward the floating electrode and away from the therapy electrode.
