#### Device Description:
AMD 6605 TENS portion: is designed to provide electrical stimulation, for the following:
· Symptomatic relief and management of chronic (long-term), intractable pain and as an adjunctive treatment in the management of post-surgical pain and post-traumatic acute pain.
The AMD 6605 NMES portion: is a portable Neuromuscular Muscular Electrical Stimulator device for the following:
- · Relaxation of muscle spasms
- · Prevention or retardation of disuse atrophy
- · Increasing local blood circulation
- · Muscle re-education
- · Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis and
- · Maintaining or increasing range of motion
The AMD 6605 is a 2 channel TENS/NMES stimulator device that is used to help reduce pain, with each channel being isolated from the other. The AMD 6605 is a programmable device that come equipped with 10 preset programs along with 10 user programs. The user programs are adjustable and can be changed to best help the patient at the doctor's recommendation and prescription settings. The program modes are preset programs that a clinician can conveniently choose from should they desire. This device has a special masking program to make the unwanted programs unavailable to the patients while locking the device in the needed relief setting. This way the patient does not receive the knowledge or ability to change the doctor's prescription settings without a clinician's consent. The AMD 6605 is programmed to default to program P-10 which contains the most common setting.
The device gives the clinician ability to store frequencies or to choose from a set of many frequencies that allow quick and easy selection, for prescription of stimulation regimen that can be later stored in any of the many available memory slots. However once the program is set the patients does not have the ability to alter the program from what the doctor or licensed practitioner has deemed to be the most appropriate program for their patient's needs.
The AMD 6605 has the following specifications: There is pulse mode with a bi-phase retangular pulse, the pulse frequency is 1 Hz to 3.65KHz, the pulse width is 30us, and the pulse amplitude is 140 levels(less than 70mA peak into 1000 ohms load to each channel). The power supply of AMD 6605 is 6.0V DC; this is supplied by four AAA type batteries.

7. Full package carrying case.
8. Personal carrying device.
#### Waveform Description
See attached Waveform pages that show different waveforms that are available for different protocols as the physician/clinician sees to be most appropriate for the patient.
Note: In order to name these modes and variations, we simply label them as variations P1, P2, P3... P 10. All wave variations have same indications of use. See waveform charts enclosed.
Note: The AMD 6605 has been preset to default to the pre-programmed mode of P-1 0 and cannot be changed unless under the orders of the treating physician or medical practitioner. This was decided for simplicity in operation, training, and operation for the patient need only turn the unit on and turn the intensity up to the desired comfort level that is best relieving the pain symptoms. The characteristics of the device can be varied and changed however only if the other programs are unmasked or unhidden by the medical practitioner.
### Indications for use
#### Indications for TENS function:
· Symotomatic relief and management of chronic (long-term), intractable pain and an adjunctive treatment in the management of post-surgical pain or post-traumatic acute pain.
#### Indications for NMES function:
- · Relaxation of muscle spasms
- · Prevention or retardation of disuse atrophy
- · Increasing local blood circulation
- · Muscle re-education
- · Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
- · Maintaining or increasing range of motion
There is no clinical basis or benefit for selecting one variation over the other. It is up to the physician to choose the correct placement, regimen and program to be used for chronic or acute pain relief along with whatever muscle function therapy that is being delivered to the patient ..
It is AMD's belief that this should be for distribution by Rx only by order of a physician or a medical practitioner. The predicated devices that have been shown to be like products are marketed in the same manner.
This is a Class II medical device by FDA standards and believed to be the standard format that should be followed in classification and prescribing methods.

The design of both the applied for device and the predicate device are substantially equivalent to each other in almost every way. The AMD 6605 has basic technological characteristics that are substantially equivalent to the TENS and NMES (Powered Muscle Stimulator) predicate devices. They all have presst output energy levels selectable by depression of a button. All units store and recall the desired treatment as selected by the physician or medical . practitioner. All units have biocompatible shrouded cables that comply with the FDA's Final Rule "Medical Devices: Establishment of Performance Standards for Electrode Lead Wires and Patient Cables". All of the units are power sourced by battery. All of the devices also deliver the stimulation inpulses through biocompatible electrodes that have a contact membrane that is made from an Amgel product (US mainufactured) or equivalent materials. The predicate device uses a 9 volt battery and the AMD 6605 uses 4ea. AAA alkaline batteries.
Both devices have two independently controlled channels, with a retangular wave form, a pulse width of 300 uS. The predicate device has a stronger output current (100mA) than the AMD 6605's (70mA). The AMD 6605 gives a muscle contraction that is not quite as intense as the predicate device and is considered an equivalent device in working on relieving pain and muscle re-education ability. We have evaluated both devices side by side matching the specifications and outputs as they relate to the AMD 6605
