Trial neuro stimulator with lead diagnostics
First Claim
1. A trial neuro stimulator with diagnostics for screening a patient to evaluate the efficacy of neuro stimulation, comprising:
- a processor;
a memory coupled to the processor containing a therapy program;
a therapy module operated according to the therapy program to produce stimulation signals, the therapy module hat a therapy module connector that includes at least one therapy connector plug;
a therapy lead having a proximal end with a therapy lead connector, the therapy lead connector configured to couple with the therapy module connector and including at least one lead connector pin that is received by the therapy connector plug;
a lead diagnostic module coupled to the therapy module connector and coupleable to the therapy lead connector, the lead diagnostic module configured for determining whether the therapy lead is operational to deliver stimulation signals; and
a switch, wherein the lead connector pin actuates the switch;
the lead diagnostic module determines whether the therapy lead is operational to deliver stimulation signals by detecting whether the therapy lead connector is operationally connected to the therapy nodule connector based on actuation of the switch, and the trial neuro stimulator is not suitable for implantation into the patient.

Abstract
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 operation. A method for diagnosing whether a therapy lead is operational is also disclosed.
