Intended Use

The BTL Elite is intended for use in applying therapeutic deep heat for selected medical conditions by applying electromagnetic energy in the radio frequency band of 27.12 megahertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies.

Device Story

BTL Elite is a shortwave diathermy system delivering 27.12 MHz electromagnetic energy to generate deep tissue heat. System comprises a power supply, electromagnetic generator, control unit with 5.7-inch touch screen, and various capacitive/inductive applicators. Operated by clinicians in a clinical setting. Capacitive method uses high-frequency electric field between insulated electrodes; inductive method uses induction to create high-frequency currents in tissue. Operator manually sets and saves treatment parameters. Safety features include a neon check light for capacitive energy verification, continuous output monitoring, and a patient-operated safety switch to terminate energy emission. Device aims to provide therapeutic deep heating for pain relief, muscle spasm reduction, and increased joint mobility.

Clinical Evidence

No clinical data provided; substantial equivalence is based on bench testing and comparison of technical characteristics to predicate devices.

Technological Characteristics

Shortwave diathermy system; 27.12 MHz RF energy source. Capacitive and inductive applicator configurations. Cabinet-mounted with wheels. 5.7-inch color touch screen interface. Microprocessor-controlled output. Continuous and pulsed modes (up to 400W pulsed, 200W continuous).

Indications for Use

Indicated for applying therapeutic deep heat to body tissues to relieve pain, reduce muscle spasms, increase range of motion of contracted joints via heat and stretch techniques, and increase blood flow to treatment areas.

Regulatory Classification

Identification

### IV. Intended Use

The BTL Elite is intended for use in applying therapeutic deep heat for selected medical conditions by applying electromagnetic energy in the radio frequency band of 27.12 megahertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies.

#### V. Device Description

The BTL Elite is a shortwave diathermy system intended for the therapeutic application of deep heating. The control unit consists of the control system and the electronic system. The control system contains the main microprocessor and software for control of the entire equipment; the electronic system contains the complete electronics for electromagnetic field generation. The device is operated via a 5.7 inch color touch screen and graphic user interface that allows for maximum operator comfort. A large control knob is provided to increase and decrease output power.

A neon check light is provided to verify that radiofrequency energy is being transmitted between the capacitive applicators. If such energy is transmitted, the indicator illuminates. If the initial energy is set too low, the check light will not illuminate. The check light is not designed for the use with inductive applicators.

For therapeutic procedures, various capacitive and inductive applicators are available. Applicators of various size are available to accommodate different size treatment areas. Applicators are connected to the rear of the main unit using the connector cable and are affixed to the adjustable arm.

With the capacitive field method, the treated body part is located in the highfrequency electric field between two insulated electrodes. The body and the applicators together form a capacitor. The transformation of electromagnetic energy into heat occurs in tissues of low blood circulation. Thus, the major amount of heat is generated in areas near the surface. While contact application causes intensive warming of superficial tissues, contactless application causes deeper warming. The inductive field method produces high-frequency electric currents within the body tissue by means of induction. These currents increase with increasing electric conductivity of the corresponding tissue region. The danger of excessive heating of the outer layers of tissue is therefore significantly reduced.

Individual treatment parameters can be manually set and adjusted by the operator. All treatment parameters can be set and saved as a reference for future therapy sessions.

The BTL Elite control unit continuously monitors the output of the system for safe operation. In addition, output can be terminated at any time during a treatment session by the patient pulling the safety switch. If the therapy is stopped by pulling the safety switch, the applicator immediately stops emitting electromagnetic energy and the unit switches to a pause mode. Patient safety is assured through a number of ways including proper maintenance of the system, operator training, and adherence to the general safety precautions and instructions provided in the user manual.

#### VI. Performance Data

The review of the technical characteristics, indications for use, and verification and validation information provided in the 510(k) Premarket Notification demonstrates that the BTL Elite system is substantially equivalent to its predicate devices.

### VII. Substantial Equivalence

The BTL Elite System is substantially equivalent to its predicate devices when used according to its intended use. This is based on the information provided in this 510(k) Premarket Notification which demonstrates that the BTL Elite System shares the same technological characteristics, mechanism of action, intended use and physical properties when compared to its predicates.
