The Guideline 5 has full featured multi-source stimulation capabilities. Stimulation modes of constant voltage or constant current mode are available with a compliance voltage of ±14V. The UE Interface is capable of microstimulation (±100µA max) through the microelectrode as well as macrostimulation (±10mA max) through the macro-contact. During stimulation, the voltage applied to the electrode is monitored and displayed constantly. The LF provides macro-stimulation. Every channel has its own stimulation circuit, allowing the Guideline 5 to perform the complex simultaneous multi-channel, multireturn stimulation protocols required for current shaping and steering. Channels not involved in the stimulation continue to record activity while an adaptive suppressor minimizes stimulus artifacts.
Integrated Impedance Check functionality for microelectrodes, macro-contacts and LF electrodes can be performed easily for monitoring the state of all connected electrodes. Measurement frequency and duration are user adjustable. The low measurement current of 1μApp minimizes any effect of the measurement on microelectrode properties. Simultaneous measurement of all channels provides quicker results. An automated power on self-test verifies proper operation and calibration of all stimulation and impedance check circuitry prior to every use of the Guideline 5 system.
The Guideline 5 is capable of recording any or all activity on an event-by-event basis or continuously. Recorded waveforms can be reviewed and analyzed intraoperatively or post-operatively. Sample Matlab™ scripts provided allow for more advanced analyses of electrode and auxiliary data suitable for research applications.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance data of the microTargeting™ Guideline 4000™ 5.0 System is documented in the verification and validation reports. Electrical Safety Test, Mechanical Integrity test, Macrostimulation test, Microstimulation test and Software regression test results show the system to be the equivalent to the predicate system.
Test: Electrical Safety
Test Method Summary: Electrical Safety consistent with IEC 60601 (Class 1 ME Equipment). Internal Testing based on IEC 60601 protocols. 60601-1 Electrical Safety Testing Performed Externally by 3rd Party entity.
Results: Both internally and externally performed electrical safety testing on subject device per standard IEC 60601 passed the acceptance criteria necessary for establishing basic safety. The subject and predicate device were both exposed to the same 60601-1 electrical safety testing therefore a substantive equivalence is established.
Test: Mechanical Integrity
Test Method Summary: Mechanical Strength and Integrity testing consistent with standard IEC 60601 Internal Testing based on IEC 60601 protocols. 60601-1 Mechanical Strength Testing Performed Externally by 3rd Party entity.
Results: Both internally and externally performed mechanical strength testing on subject device per standard IEC 60601 passed the acceptance criteria necessary for establishing basic safety. The subject and predicate device were both exposed to the same 60601-1 mechanical strength testing therefore a substantive equivalence is established.
Test: Macro Stimulation
Test Method Summary: The test method employed is an internally generated protocol in which the subject device is assessed on three key parameters relevant to the safe and effective delivery of therapeutic electrical stimulus. These parameters include: -Accurate output frequency -Accurate pulse duration -Accurate stimulus amplitude. Each parameter is adjusted via the software user interface. Each parameter is then measured using a NIST traceable oscilloscope with the subject device's output terminated with precision resistive loads which act as microelectrode analogs.
Results: The subject devices met the acceptance criteria necessary for establishing accuracy of stimulator outputs to within ±10% of the User Interface set point for frequency, pulse duration, and amplitude. Given the predicate device provides the same accuracy, a substantive equivalence is established.
Test: Micro Stimulation
Test Method Summary: The test protocol used for Macro Stimulation mode also applies to Micro stimulation with the exception of the latter outputs an order of magnitude lower stimulus amplitude.
Results: The subject devices met the acceptance criteria necessary for establishing accuracy of stimulator outputs to within ±10% of the User Interface set point for frequency, pulse duration, and amplitude. Given the predicate device provides the same accuracy, a substantive equivalence is established.
Test: Software regression testing
Test Method Summary: The internally created software regression test protocol is based on the workflow established in the Usability specification of the predicate device. It is performed iteratively at each software release per IEC 62304. All major and minor software functions were tested iteratively prior to each release of a new software revision. Additionally, bugs fixed since the previous round of regression testing were assessed for effectiveness and risk.
Results: All major areas of software functionality were confirmed for the subject device. No remaining bugs had a risk level of greater than Acceptable as defined by risk management plan. Over the course of its life-cycle, the predicate device received similar treatment with respect to bug fixes, bug risk acceptance, software releases, and regression testing. As such, substantive equivalence is established.

7. Nonclinical performance Data:
Performance data of the microTargeting™ Guideline 4000™ 5.0 System is documented in the verification and validation reports. Electrical Safety Test, Mechanical Integrity test, Macrostimulation test, Microstimulation test and Software regression test results show the system to be the equivalent to the predicate system.
| Test | Test Method Summary | Results |
|---|---|---|
| Electrical | ||
| Safety | Electrical Safety consistent | |
| with IEC 60601 (Class 1 ME | ||
| Equipment) | ||
| Internal Testing based on IEC | ||
| 60601 protocols. | ||
| 60601-1 Electrical Safety | ||
| Testing Performed Externally | ||
| by 3rd Party entity. | Both internally and externally | |
| performed electrical safety testing on | ||
| subject device per standard IEC | ||
| 60601 passed the acceptance criteria | ||
| necessary for establishing basic | ||
| safety. The subject and predicate | ||
| device were both exposed to the | ||
| same 60601-1 electrical safety testing | ||
| therefore a substantive equivalence is | ||
| established. | ||
| Mechanical | ||
| Integrity | Mechanical Strength and | |
| Integrity testing consistent | ||
| with standard IEC 60601 | ||
| Internal Testing based on IEC | ||
| 60601 protocols. | ||
| 60601-1 Mechanical Strength | ||
| Testing Performed Externally | ||
| by 3rd Party entity. | Both internally and externally | |
| performed mechanical strength | ||
| testing on subject device per | ||
| standard IEC 60601 passed the | ||
| acceptance criteria necessary for | ||
| establishing basic safety. The subject | ||
| and predicate device were both | ||
| exposed to the same 60601-1 | ||
| mechanical strength testing therefore | ||
| a substantive equivalence is | ||
| established. | ||
| Macro | ||
| Stimulation | The test method employed is | |
| an internally generated | ||
| protocol in which the subject | ||
| device is assessed on three | ||
| key parameters relevant to the | ||
| safe and effective delivery of | ||
| therapeutic electrical stimulus. | ||
| These parameters include: | ||
| -Accurate output frequency | ||
| -Accurate pulse duration | ||
| -Accurate stimulus amplitude | The subject devices met the | |
| acceptance criteria necessary for | ||
| establishing accuracy of stimulator | ||
| outputs to within ±10% of the User | ||
| Interface set point for frequency, | ||
| pulse duration, and amplitude. Given | ||
| the predicate device provides the | ||
| same accuracy, a substantive | ||
| equivalence is established. | ||
| Each parameter is adjusted via | ||
| the software user interface. | ||
| Each parameter is then | ||
| measured using a NIST | ||
| traceable oscilloscope with the | ||
| subject device's output | ||
| terminated with precision | ||
| resistive loads which act as | ||
| microelectrode analogs. | ||
| Micro | ||
| Stimulation | The test protocol used for | |
| Macro Stimulation mode also | ||
| applies to Micro stimulation | ||
| with the exception of the | ||
| latter outputs an order of | ||
| magnitude lower stimulus | ||
| amplitude. | The subject devices met the | |
| acceptance criteria necessary for | ||
| establishing accuracy of stimulator | ||
| outputs to within ±10% of the User | ||
| Interface set point for frequency, | ||
| pulse duration, and amplitude. Given | ||
| the predicate device provides the | ||
| same accuracy, a substantive | ||
| equivalence is established. | ||
| Software | ||
| regression | ||
| testing | The internally created | |
| software regression test | ||
| protocol is based on the | ||
| workflow established in the | ||
| Usability specification of the | ||
| predicate device. It is | ||
| performed iteratively at each | ||
| software release per IEC |
All major and minor software
functions were tested
iteratively prior to each
release of a new software
revision. Additionally, bugs
fixed since the previous round
of regression testing were
assessed for effectiveness and
risk. | All major areas of software
functionality were confirmed for the
subject device. No remaining bugs
had a risk level of greater than
Acceptable as defined by risk
management plan.
Over the course of its life-cycle, the
predicate device received similar
treatment with respect to bug fixes,
bug risk acceptance, software
releases, and regression testing. As
such, substantive equivalence is
established. |
