This Tap-Water-lontophoresis device is intended to treat hyperhidrosis (pathological sweating) affecting hands, feet and underarms.

Any other use or usage bevond this scope is considered un-intended use and may have dangerous consequences.

Scientific Concept:

lontophoresis is a physical process in which ions flow diffusively in a medium driven by an electric field. Iontophoresis is to be distinguished from the carriage of uncharged molecules by diffusive fluxes of other molecules, especially of solvent molecules.

ln the treatment of hyperhidrosis, tap water is often the chosen solution for mild and medium forms.

Since 1968, tap water iontophoresis has been employed as the method of choice for treating palmoplantar hyperhidrosis. Special electrodes also allow treatment of axillary hyperhidrosis. Tap water iontophoresis also can extend symptom -free intervals in dyshidrotic palmar eczema. The mechanism action is most likely a functional disturbance of the secretory mechanism of eccrine acini. During the induction phase, treatments are carried out once daily. Current direction may be switched before each treatment or, even better, kept constant until one side, preferably the dominant hand on the anode, is sweating normally. Then polarity is switched until both hands are adequately treated. During the weekly maintenance therapy, current direction is switched before each treatment. The most comfortable means of iontophoretic treatment employs pulsed direct current of high frequency (5-10 kHz) which is better tolerated than continuous direct current. Side effects are minimal and transient. Only slight skin irritation or sensations of discomfort may occur during treatment. Electric burns and shocks can be avoided by following routine precautions. Contraindications for tap water iontophoresis are metallic implants, such as cardiac pacemakers, or orthopaedic joint or bone implants, if they are within the electric circuit.

Device Description:

HIDREX iontophoresis devices are primarily intended for treating hyperhidrosis1 (excessive sweating) of hands and/or feet. Provided the optional axillary applicators are utilized, the system can also be used for treating axillary hyperhidrosis.

Function:

The HIDREX treatment concept comprises two treatment phases:

Phase 1: The initial phase (therapy initiation) is conducted under a doctor's supervision with the doctor's or the patient's device. During this stage, patients learn to administer treatments. For therapy initiation, three weekly treatments of approximately 15 minutes each should be scheduled (not more than one treatment per day). Sweat secretion will normalize after approximately 10 treatments.

Phase 2: Long term treatment (maintenance therapy) is necessary because the HIDREX treatment effect is reversible. Patients should conduct maintenance therapy sessions by themselves at home and with their own unit. Depending on the severity of the condition, maintenance therapy involves one to three weekly sessions of approximately 15 minutes each.

The Hidrex PSP1000 with changeable pulse-width allows the innovative adjustment of the pulse-intensity.

Extensive trials showed that the efficiency of pulsed current could be increased dramatically. The effectiveness is not reduced at all compared to direct current when the pulse-width is 90%. The possible pulse-widths are 50%, 60%,70%, 80%, 90% and 100%

Application:

Difference's Analysis

These technical differences were identified:

Subject device (sd)Predicate device (pd)
1.DC-current output max. 35mADC-current output 0-10 and 0-50mA
The pd has two output ranges because it uses an analog Ampere-meter. It is very
likely to make reading-mistakes using a wide-range-scale while operating in a low-
current mode. Therefore, the manufacturer suggests to use the low-range-scale (0-
10mA), while using the device in the low-current-mode. However, it is still likely to
make mistakes.
The sd has a display that shows digital digits. No matter what the current-mode is, it
is unlikely to make reading-mistakes. Therefore there is no need to have separated
scale-ranges.
2.DC and pulsed-current outputOnly DC-current output
A pulse-width of 100% (no pause) is corresponding to the classical DC method.
However, pulse-width-method makes the sensation for the user more present because of
the physiological 10kHz frequency. The pulsed current output modes are more sensitive.
So the risk of skin-irritation is reduced.
3.Automatic current regulation and over-
current protectionOver-current protection
The pd, due to its basic concept with analog technology, has a manual current
adjustment. The patient/user has to read continuously the analog meter to stay with
the appreciated settings.
The sd has a microprocessor that is able to watch physical conditions. The sd can
automatically adjust the current and keep the therapeutic settings based on the
patient's settings. Physical changes caused by the patient, like position or
movements, can automatically be compensated.
4.Timer
The pd has no timer. The patient has to measure and check the time span for the
treatment-session by himself.
The sd has a timer that automatically starts the countdown when the treatment
starts. The patient's benefit is the automatic ending of the treatment session. The risk
for an overdose is reduced.
5.DisplayAnalog meter
The pd has an analog Ampere-meter. It is very likely to make reading-mistakes using
a wide-range-scale while operating in a low-current mode. It is also necessary to
have god visibility to be able to read the relatively small numbers on the meter.
Reading mistakes are likely.
The sd has a display with big digital digits. The display shows the setting as well as
the current. The possibility to make reading mistakes is unlikely.
6.microprocessorAnalog technology
The pd operates based on analog technology.
The sd operates based on digital technology. The advantage is to be able to check
and control the treatment-parameter during the session, to reduce the weight of the
device and offer more adjustment for treatment-parameter.
7.Digital MonitorAnalog meter
The pd has an analog Ampere-meter. It is very likely to make reading-mistakes using
a wide-range-scale while operating in a low-current mode. It is also necessary to
have god visibility to be able to read the relatively small numbers on the meter.
Reading mistakes are likely.
The sd has a display with big digital digits. The display shows the setting as well as
the current. The possibility to make reading mistakes is unlikely.
8.Soft sensor buttonsAnalog switch/knob
Analog switches and knobs are subject to corrosion. It is likely that their precision
and even functionality is reduced after a few years of use.
The sd has foil-insulated micro-switches. They last much longer and it is unlikely that
they loose their functionality at all.
9.Application accessory axillary-spongeNo axillary-sponge
Some patients suffer also from axillary hyperhidrosis. To offer effective treatment
also for these patients the sd has specialized accessory.
10.External power supplyInternal Power supply
The pd has an internal power supply while the sd has an external power supply.
There are no significant differences concerning safety or comfort. A break in the
power supply can be fixed more easily with an external one.

Each of these logos also has an orange graphic to the left of the text.

The above mentioned differences between the subject device and the predicate device are due to technological progress. The subject device and its modern technology increase the comfort and benefit for the patient in using the device. Misuse or misunderstanding by using an analog meter is impossible with the clear digital-display of the subject device. All settings are protocolled and displayed in the display. This avoids mistakes in the user-setting. The additional benefit of the pulsed-current is demonstrated in several clinical trials. The safety of the device was demonstrated in non-clinical tests according to recognized standards.

Comparison between materials and principles of use

The HIDREX PSP1000 as well as the predicate device MD-1A GALVANIC UNIT by R.A. Fischer Co. (K964208) use a standard housing made from ABS-Plastic. This housing material is non-toxic and used with many other devices. The same is true for the trays/cases that are used to apply the therapy. None of these materials is in direct contact with the skin for medical purpose. Both devices, the subject device as well as the predicate device, use standard-household-towels that are in direct contact with the patients skin.

The system components are the same. Both systems consist of a central-unit and application components. The subject device has in addition to the foot- and hand-applicator also an axillary applicator. Therefore the subject device offers more benefit to the user than the predicate device.

The principles of use are basically the same. The subject device uses a modern technology like LCD-display to display the setting etc., micro-buttons to adjust and digital controlled processes, while the predicate device has analog technology, like an analog meter to display the current, analog resistor-knob for adjustments and no digital control. Therefore the subject device offers higher comfort and control and advanced usability.

The performance of the subject device and the predicate device are similar concerning the standard dc-current-therapy. The subject device offers a pulsed current in addition, which makes the sensation for the user more present because of the physiological 10kHz frequency.

To the right of the logo are three other logos, MED, VET, and REHA. Each of these logos has a small orange circle to the left of the word, and the words are written in blue except for VET which is green.

In conclusion the differences between the subject device and the predicate device don't lead to any harm of the patient or third persons. Comfort and usability is increased with the subject device compared to the predicate device.

Comparison between principles of use

The HIDREX PSP1000 has nearly the same system components as the predicate device Drionic by General Medical Company (K831320). Both systems consist of a unit for hand and foot treatment and an application component for underarm treatment.

The principles of use are basically the same. The subject device uses a modern technology like LCD-display to display the setting etc., micro-buttons to adjust and digital controlled processes, while the predicate device has old technology like an analog control wheel to adjust the intensity, a light to display the operating state and no digital control. Therefore the subject device offers higher comfort and control and an advanced usability.

The performance of the subject device and the predicate device are the same concerning the standard dc-current-therapy. In addition the subject device offers a pulsed current which makes the sensation for the user more present because of the physiological 10kHz frequency.

Difference's Analysis

These technical differences were identified:

Subject device (sd)Predicate device (pd)
1.DC-current output max. 35mA
The pd has two output ranges because it has no Ampere-meter.
The sd has a display that shows digital digits. No matter what the current-mode is, it
is unlikely to make reading-mistakes. Therefore there is no need to have separated
scale-ranges.DC-current output 6-14mA and 1-2,5mA
2.DC and pulsed-current output
A pulse-width of 100% (no pause) is corresponding to the classical DC method.
However, pulse-width-method makes the sensation for the user more present because of
the physiological 10kHz frequency. . The pulsed current output modes are more
sensitive. So the risk of skin-irritation is reduced.Only DC-current output
3.Polarity reversal (to alternate POS and
NEG application)
The pd has no possibility to change the polarity.
The sd provides a manual adjustable reversible polarity. The user is able to change
between positive and negative application.--
4.Automatic current regulation and over-
current protection
The pd has a manual adjustment. The patient/user has to advance the control wheel
until there is a comfortable tingle. During the treatment-session the patient/ user is
responsible for the intensity by himself without any technical help.No automatic regulation or protection

The above mentioned differences between the subject device and the predicate device are due to technological progress. The subject device and its modern technology increases the comfort and benefit for the patient in using the device. Because of the automatic current regulation and protection the risk of a harmful high intensity and of an overdose is reduced. All settings are protocolled and displayed in the display. This avoids mistakes in the user-setting. The additional benefit of the pulsed-current is demonstrated in several clinical trials. The attached trial is an explanation as to why the higher levels of voltage and current do not affect safety and effectiveness of the subject device. Furthermore, the safety of the device was demonstrated in non-clinical tests according to recognized standards.
