The description focuses on radiofrequency energy delivery, a microprocessor-driven control unit, and a user interface, with no mention of AI or ML terms or functionalities.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated to be used for applying therapeutic deep heat in body tissues for the treatment of selected medical conditions."
No
The device's intended use and function are described as applying therapeutic deep heat to body tissues for treatment, not for diagnosis.
No
The device description clearly states it is comprised of a device unit and applicator that deliver radiofrequency energy, indicating it is a hardware device with software control, not a software-only device.
Based on the provided information, the BTL-703 is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly describes a therapeutic device that applies deep heat to body tissues for treating various medical conditions like pain relief, muscle spasm reduction, and increasing range of motion and blood flow. This involves direct interaction with the patient's body.
- Device Description: The device description details a system that delivers radiofrequency energy to targeted tissue via an applicator. This is a physical intervention on the body.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. The BTL-703 does not perform any such analysis of specimens.
The BTL-703 is a therapeutic device that delivers energy to the body for treatment purposes, which is distinct from the function of an IVD device.

Animal Testing
In order to demonstrate the device is able to maintain temperature in the range of approx. 40-45°C in vivo, study in porcine model has been conducted. The results of this evaluation confirmed the ability of the BTL 703 device to maintain the temperature in the range of approx. 40-45°C in vivo.
Technological Characteristics
The BTL-703 device has similar technological characteristics compared to its predicate. Both devices comprised of a system console and applicator(s). The system console consists of the RF generator, computer, and the touch-screen control panel.
Both devices use high-frequency electromagnetic current for a purpose of deep heating of tissue. The BTL-703, compared to the predicate device, does not included pulsed mode of operation and inductive type of applicator. Output power of BTL-703 is divided into two outputs for more even energy distribution. Nevertheless, total maximum power output stays the same (200W) as by the predicted device. The working frequency is identical for both devices.
The BTL 703 is using neqative pressure for applicator fixation compared to the predicate device using mechanical arm. Negative pressure under silicone applicator sleeves ensures uniform coupling between the capacitive electrodes and patient. The BTL-703 device also differs in the shape and dimensions when compared to its predicate. Nevertheless, these differences does not rise any new safety or effectiveness questions compared to the predicate.
Therefore, the BTL-703 has similar technological characteristics compared to its predicate device. A device comparison table comparing characteristics of the BTL-703 with the BTL Elite including the indications for use, is provided below.
