Device Story

Xcite Clinical Station is a multichannel Functional Electrical Stimulation (FES) system for general rehabilitation. Input: therapy settings managed via tablet PC. Operation: tablet-controlled stimulators deliver coordinated electrical pulses (0-140mA, 50-500usec, 10-100Hz) to peripheral nerves via cutaneous electrodes. Output: electrical stimulation to specific muscle groups (quadriceps, hamstrings, gluteals, gastroc, anterior tibialis, shoulder, deltoids, wrist, abdominals, erector spinae). Used in clinical settings by healthcare providers to facilitate muscle re-education, increase circulation, and prevent atrophy. System includes tablet, up to two 6-channel stimulators, stimulation cables, electrodes, mobile cart, and remote database interface for therapy logs/settings. Benefits: non-invasive muscle activation, improved range of motion, and post-surgical thrombosis prevention.

Clinical Evidence

Bench testing only. Validation testing performed on the Xcite Clinical Station with 12 stimulation channels using five neurologically impaired individuals. Electrical safety and EMC testing confirmed compliance with IEC60601-1, ANSI/AAMI ES60601-1, IEC60601-1-2, IEC60601-1-11, and IEC60601-2-10.

Technological Characteristics

Multichannel FES system; tablet-based controller; up to two 6-channel DC-powered stimulators (0-140mA, 50-500usec, 10-100Hz); cutaneous electrodes; mobile cart; remote database interface. Standards: IEC60601-1, ANSI/AAMI ES60601-1, IEC60601-1-2, IEC60601-1-11, IEC60601-2-10. Mains and rechargeable battery power.

Indications for Use

Indicated for general rehabilitation in patients requiring muscle spasm relaxation, disuse atrophy prevention/retardation, local blood circulation increase, muscle re-education, post-surgical calf stimulation for venous thrombosis prevention, and range of motion maintenance/increase. Prescription use only.

Table 1 Device technology comparison

## (7) Performance data

Non-clinical testing to determine equivalence has been primarily composed of the following tests:

| Test or procedure | Description |
|-------------------------------------------------------|--------------------------------------------------------------------------------------------------|
| Review of user documentation for<br>predicate devices | Ensure that equivalent functionality is<br>specified and implemented in the new<br>device. |
| Output characteristic measurement of<br>new device | Confirm technical specifications for<br>completion of new device details in<br>comparison tables |
| Conduct of system testing | Conduct system testing to verify<br>performance to specification. |

| Validation Testing | Description |
|------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|
| Testing the Xcite Clinical Station | The Xcite Clinical Station with 12<br>stimulation channels was evaluated<br>with five neurologically impaired<br>individuals. |

#### Electrical safety and electromagnetic compatibility (EMC)

Electrical safety and EMC testing were conducted on the Xcite Clinical Station. The system complies with Electromagnetic Compatibility and Electrical Safety The Xcite system conforms to the following standards; IEC60601-1, ANSI/AAMI ES60601-1,IEC60601-1-2, IEC60601-1-11, and IEC60601-2-10.

#### RTI concludes that:

Xcite Clinical Station has the same intended use as the RT300 and Elpha 2000 predicate devices.

{8}------------------------------------------------

Xcite utilizes the same FES stimulators and stimulation control system as the RT300 predicate device. The different technological characteristics do not raise new questions of safety and effectiveness.

In conclusion, RTI's testing and validation testing has demonstrated that Xcite is as safe and effective as the predicate devices.
