Indications for Use

The Wave Electrode is to be used exclusively for external prosthetic fittings of the upper limbs.

Device Story

Wave Electrode is an active analog cutaneous electrode for detecting surface electromyographic (EMG) signals to control myoelectric prosthetic hands. It detects electrical potentials from residual muscles on an amputated limb; processes and amplifies signals; and transmits an analog output (0-5V) proportional to muscle contraction to the prosthetic hand's electronic board. Used in professional healthcare facilities and home settings; operated by prosthetists during assembly and by patients during daily use. The device is integrated into the prosthetic system and requires no additional battery. It provides real-time control of prosthetic hand opening/closing. Benefits include non-invasive control of prosthetic devices for amputees.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including electrical safety (IEC 60601-1, IEC 60601-1-11), electromagnetic compatibility (IEC 60601-1-2), and biocompatibility (ISO 10993-5, ISO 10993-10, ISO 10993-23).

Technological Characteristics

Active analog electrode; dimensions 27x18x8 mm; materials ABS and AISI316L; frequency bandwidth 90-450 Hz; power 6-8.4 V DC, 2 mA. Features notch filter (50 Hz for AE02-50, 60 Hz for AE02-60). Standalone analog component; no software or firmware. Sterilization not specified.

Indications for Use

Indicated for adults with mono- or bilateral upper limb amputations (transradial level or higher) requiring external prosthetic fittings.

Regulatory Classification

Identification

A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation.

# 4. DEVICE DESCRIPTION

Wave Electrode is an active analogue electrode for detecting any surface electromyographic signals, used for controlling prosthetic devices. It is compact and low-power, ensuring an accurate and fast reading of muscle electrical potentials generated voluntarily by the user. It also provides a real-time output signal proportional to the detected muscle activation.

Therefore,

Through the Wave Electrode it is possible to non-invasively detect the electrical signal produced by the residual muscles on the patient's amputated limb (unilateral amputees, starting from a transradial amputation level) and send an electrical signal to the electronic board of the prosthetic hand with a proportional width to the detected contraction.

Wave Electrode is only compatible with the Adam's Hand that, according to the Requlation Number 890.3420, are classified as class I medical device.

Wave Electrode is available in two different models:

- . Mod. AE02-50, with notch filter centred on the 50 Hz frequency;
- . Mod. AE02-60, with notch filter centred on the 60 Hz frequency

# 5. INDICATION FOR USE

The Wave Electrode is to be used exclusively for external prosthetic fittings of the upper limbs.

Given that the Wave Electrode is intended to acquire the surface EMG signals, filter and amplify them analogically and input them to the electronics of the myoelectic hand present in the prosthesis in which the electrodes are integrated, and acknowledging a few distinctions among the devices, it can be affirmed that the subject device is substantially equivalent to the predicate devices.

(1) Although the power requirements, dimensions, and frequency bandwidth of the subject device are slightly different from the predicate devices, all of them meet the requirements of safety and performance standards IEC 60601-1. So, the differences between the predicate devices and the subject device will not affect the safety and effectiveness of the subject device.

(2) The subject device communicates directly with the upper limb prosthetic systems.

Wave Electrode is an analog device and has no on-board programmable electronics (FW and or PEMS).

The subject device cannot lead to risks resulting from programmable electronics malfunctioning than the predicates .

(3) The subject device does not include prosthetic limbs.

Performance tests have showcased the compatibility of the Wave Electrode with only Adam's Hand prosthetic limb that can be utilized in conjunction with it.

(4) Although the contact materials of the subject device are different from the predicate devices, all the materials that in NORMAL USE come into contact to the PATIENT meet the requirements of ISO 10993 series standards. So, the differences between the predicate device and the subject devices will not affect the safety and effectiveness of the subject device.

(5) Although the subject device, the predicate device I (primary), and the predicate device II (secondary) use slightly different versions of the test standards, the subject device is in compliance with the state of art standards. So, the differences between the predicate devices and the subject device will not affect the safety and effectiveness of the subject device. The ISO 10993- 23 specifies the procedure for the assessment of medical devices and their constituent materials with regard to their potential to produce irritation, this specifies was included in the ISO 10993- 10.

# 7. NON-CLINICAL PERFORMANCE DATA

Considering that the Wave Electrode is intended to be used in conjunction with "Adam's Hand({" prosthetic hand, the safety of the electrodes have been demonstrated through the tests performed on the whole system (Electrodes + "Adam's Hand(B)" prosthetic hand)

- . Electrical safety test according to IEC 60601-1 and IEC 60601-1-11 standards
- . Electromagnetic compatibility test according to IEC 60601-1-2 standard

The Wave Electrode does not require an additional battery beyond the one present in the upper limb prosthetic system, and not included any software.

Wave Electrode has been directly evaluated for the biological safety to exclude the toxicological concerns, by an accredited laboratory as following:

To the right of the figure is the text "BIONIT LABS" in bold, black letters. Below the text is a blue rectangle with the words "TURNING DISABILITIES INTO NEW POSSIBILITIES" in white letters.

- Cytotoxicity testing per ISO 10993-5 .
- . Skin irritation testing per ISO 10993-10
- . Sensitization testing per ISO 10993-23

The Wave Electrode was also tested internally to ensure that it meets design specifications & requirements and operates as intended when is used in conjunction with "Adam's Hand®" prosthetic hand.

# 8. CLINICAL PERFORMANCE DATA

No human clinical testing was required to support the medical device as the indications for use is equivalent to the predicate device. These types of devices, including the predicate device, have been on the market for many years with proven safety and efficacy for the use of the nonclinical testing detailed in this submission supports the substantial equivalence of the device.

# 9. STATEMENT OF SUBSTANTIAL EQUIVALENCE

The technological characteristics, features, specifications, mode of operation, and intended use of Wave Electrode are substantially equivalent to the electrodes included in the Dexus Prosthetics System and the electrode Alpha Control Liner System (ACLS) quoted above.

The differences between the subject device and primary predicate device do not raise new issues of safety or effectiveness. Thus, the subject device is substantially equivalent to the already placed on the US market primary predicate device K220002.
