Yes
The device is intended for the relief of chronic intractable pain, adjunctive treatment of acute pain, relaxation of muscle spasms, prevention of disuse atrophy, muscle re-education, increasing local blood circulation, maintaining or increasing range of motion, and immediate post-surgical stimulation of calf muscles to prevent venous thrombosis, which are all therapeutic indications.
No
The document describes the device's intended use for pain relief and muscle stimulation, not for diagnosing medical conditions.
No
The device description explicitly states, "Since there is no microprocessor, no software is needed." The device's primary functioning is analog, with digital functions being hard-wired.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The MedRelief SE Series™ devices are described as electrotherapeutic devices that apply electrical pulses to the body through electrodes placed on the skin. Their intended uses are for pain relief and muscle stimulation.
- Lack of Biological Sample Analysis: The description does not mention the analysis of any biological samples from the patient. The device directly interacts with the body's electrical system.
Therefore, the function and intended use of the MedRelief SE Series™ devices fall outside the scope of in vitro diagnostics. They are therapeutic devices, not diagnostic ones.

Device Description
The MedRelief SE Series™ provides a selection of both high-level and subthreshold electrotherapeutic modes in a compact, lightweight and userfriendly package. "Subthreshold" as used here means electrical stimulation not strong enough to cause nerve depolarization or muscle contraction, but still active at a cellular level, as in microcurrent TENS. Healthonics' proprietary version of subthreshold stimulation has been named Structured Energy™
Devices in the MedRelief SE Series™ provide combinations of these stimulation modes as follows:
| Model
number | Includes: muscle
stimulation | interferential
stimulation | Structured
EnergyTM | Controls |
|-----------------|---------------------------------|-------------------------------|------------------------|----------|
| SE-300 | X | X | X | Rotary |
| SE-200 | X* | X* | X | Rotary |
| SE-100 | -- | -- | X | Rotary |
| SE-50 | -- | -- | X | Recessed |
-
- Output provided over reduced intensity range.
Models SE-200™ and SE-300™ provide all three stimulation modes, while Models SE-50™ and SE-100™ are miniaturized, single-mode Structured Eneray™-only versions. All devices are completely powered by 9-volt batteries, without provisions for line power or AC adapters. All devices are single-channel only.
All SE Series ™ devices produce trains of brief electrical pulses which are applied to the body through self-adhesive electrodes placed on the skin. Pulses recur at a nominal 4150 Hz and may be either 30 microseconds or 120 microseconds long. These pulses form a carrier wave which may then be modulated by one of three different envelopes, yielding respectively Structured Energy™, muscle stimulation, or premodulated interferential stimulation. Envelope frequencies range from 0.25 Hz to 130 Hz, depending on the mode being used.
All functions for a particular mode are preset, and accessed through a single rotary switch which also turns the device on and off. In the SE-200™ and SE-300™, a second rotary switch provides intensity control. In the SE-100™, all control functions are integrated into a single rotary switch, while in the SE-50™ this switch is replaced by two recessed, miniature slide switches.
While the MedRelief SE Series™ incorporates some ancillary digital components such as frequency dividers, its primary functioning is analog, with all digital functions hard-wired. Since there is no microprocessor, no software is needed.

Summary of Performance Studies
Healthonics has carried out design and performance testing to address the following issues:
(1) Performance testing for the purpose of addressing the points in the FDA guidance document, "Guidance Document for Powered Muscle Stimulator 510(k)'s," dated June 9, 1999.
(2) Electrical safety. The SE Series™ was designed to comply with UL-2601 and will be tested to this standard by an independent test laboratory before marketing.
(3) Electromagnetic compatibility. The SE Series™ was designed to comply with EN 60601-1-2, May 1993. However, the FDA guidance document exempts powered muscle stimulators from compatibility requirements unless specific claims of compatibility are made. Since Healthonics makes no such claims, and since no other output mode exceeds muscle stimulation in voltage, current or power. Healthonics believes that the SE Series™ is also exempt from this requirement.
(4) Conformance to NS4-1985. The SE Series™ was designed to comply with applicable requirements of ANSI/AAMI NS4-1985, as supported by performance testing.

digital functions hard-wired. Since there is no microprocessor, no software is needed.
C. INTENDED USE.
Since the MedRelief SE Series™ is a family of devices with differing functions, only those indications which the FDA has traditionally approved for the corresponding device types are sought.
For the SE-50™ and SE-100™, which include only subthreshold stimulation substantially equivalent to subthreshold TENS devices previously cleared by the FDA, the indications sought are:
-
- Relief of chronic intractable pain.
-
- Adjunctive treatment of post-surgical or post-traumatic acute pain.
For the SE-200™ and SE-300™, which include powered muscle stimulation as well as interferential and subthreshold stimulation, the following additional indications are sought:
-
- Relaxation of muscle spasms.
-
- Prevention or retardation of disuse atrophy
-
- Muscle re-education
-
- Increasing local blood circulation
-
- Maintaining or increasing range of motion
-
- Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis.
D. SUBSTANTIAL EQUIVALENCE SUMMARY.
The MedRelief SE Series™ is a family of medical devices, having the same indications for use, target populations, and technological characteristics as the legally marketed predicate devices. This premarket notification has described the characteristics of the MedRelief SE Series™ in sufficient detail to assure substantial equivalence.
E. TECHNOLOGICAL CHARACTERISTICS.
Both new and predicate devices employ electronic circuitry to produce electrical output waveforms at closely comparable voltage and current levels and with closely comparable waveforms and timing. The MedRelief SE Series™ is primarily analog, with some hard-wired digital functions but no microprocessor and thus no software.
