Image /page/8/Picture/0 description: The image shows the logo for BTL Industries. The logo consists of a blue geometric design on the left and the text "BTL Industries" on the right. The geometric design is made up of three squares, each nested inside the other, with the letters "BTL" inside the innermost square.
The HPM-6000 device has the same indications for use and similar technological characteristics and principles of operation as its predicate device.
One of the technological differences between the subject and predicate devices includes pulse repetition rate. Therefore, K952089, a powered muscle stimulator cleared under the IPF product code (predicate of the predicate or K952089) has been submitted to demonstrate that safety and effectiveness are not adversely affected. K952089 or Rich-Mar CM-II Muscle Stimulator has pulse repetition range rate of 2-200 Hz, compared to 0-150 Hz for HPM-6000, the subject device. The mechanism of action of the electrical stimulator and this kind of magnetic device is the same. The nerve gets stimulated by electrical current and while the method of delivery is the different (magnetic induction), it is still the same current delivered to the tissue that stimulates the nerve endings on a similar frequency.
The technological differences between the HPM-6000 and predicate device, do not raise new types of safety or effectiveness questions.
The non-clinical test results confirm that the depth of tissue penetration does not differ and pulse repetition rate works in a similar manner compared to the predicate. Thus, the HPM-6000 is substantially equivalent to the predicate devices.
## Substantial Equivalence
Based upon the intended use and known technical information provided in this pre-market notification, the HPM-6000 device has been shown to be substantially equivalent to currently marketed predicate device.
## Conclusion
Based on the aforementioned information, the HPM-6000 is safe and effective and substantially equivalent to the identified predicate device.
