Device Story

Biofusionary Bebe is a shortwave diathermy device for deep tissue heating. It uses a hand-held coil-shaped antenna to generate electromagnetic energy at 27.1 MHz, inducing eddy currents in tissue that produce localized heat via resistance. The system includes a main console (RF generator, control module), footswitch, recirculating chiller, and hand piece with a 3 cm tip. Operated by clinicians in a clinical setting, the device requires manual positioning (no hands-free operation). The clinician uses timer settings and protocols to manage treatment. Patient feedback is essential to monitor sensation and prevent excessive warming. The device provides therapeutic heat to aid in pain management, muscle spasm reduction, and joint contracture treatment.

Clinical Evidence

Bench testing included heating characterization on tissue phantoms and ex vivo porcine skin, demonstrating therapeutic temperatures (40°C) reached within 5-13 minutes at depths of 0-2 cm. In vivo rat studies and two feasibility clinical studies were conducted to evaluate safety and effectiveness. A usability study with naive users confirmed that instructions were adequate for safe device operation. Occupational safety was verified against IEEE 95.1-2005 standards.

#### Summary of Substantial Equivalence

The Rocky Mountain Biosystems, Inc, Biofusionary Bebe™ is equivalent to the predicate product. The indications for use, basic overall function, methods of manufacturing, and materials used are substantially equivalent. The results of heating studies also support the substantial equivalence of the Biofusionary Bebe with the predicate device.

#### Technological Characteristics

The predicate product, the Chatanooga Intelect, is supplied with two different electrodes: the Monode (Drum) Electrode is an induction coil for treatment of mid-sized areas. The Diplode is a capacitive coupled set of electrodes for treatment of large areas and for treatment of suitable body parts that can be warmed from three sides at the same time. The device may be operated in pulsed or continuous mode.

The drum electrode, an induction coil, has a 14 cm diameter. It is fixed in size and attached to a boom that allows it to be positioned at a single location on the patient. The fixed nature of the electrode allows the operator to provide hands-free treatment of a 14 cm diameter area of the skin.

The operation of the Biofusionary Bebe device is most similar to the use of the Intelect Monode Electrode used in continuous mode

The Biofusionary Bebe device has a hand piece with 3 cm diameter tip. The device operates in continuous mode at 170W. The device allows the operator to treat a 12 cm diameter area by choosing timer settings and protocols. Hands-free operation is not possible.

#### Power delivery

Both devices operate at 27.1 MHz.

The Intelect allows for operation in a pulsed mode (200 W) with a variable duty cycle, or a continuous mode (100 W) with variable power settings. The Biofusionary Bebe operates in a fixed continuous mode at 170W.

The operation of the Biofusionary Bebe device is most similar to the use of the Intelect Monode used in continuous mode operation.

#### Applicator

The Intelect is supplied with a drum electrode, the induction coil, which has a 14 cm diameter. It is fixed in size and attached to a boom that allows it to be positioned at a single location on the patient. The fixed nature of the electrode allows the operator to provide hands-free treatment of a 14 cm diameter area of the skin.

The Biofusionary Bebe device has a hand piece with 3 cm diameter tip. The device allows the operator to treat a 12 cm diameter area by choosing timer settings and protocols. Hands-free operation is not possible.

{4}------------------------------------------------

#### Heating Capabilities

Two different electrode configurations are available for the Intelect. The Monode (Drum) Electrode is an induction coil for treatment of mid-sized areas. The Diplode is a capacitive coupled set of electrodes for treatment of large areas and for treatment of suitable body parts that can be warmed from three sides at the same time.

The devices manage deep or shallow heating capabilities in similar manner:

Both devices heat to therapeutic temperatures for a minimum of 1 minute, and the maximum recommended treatment time is 30 minutes. Both devices provide therapeutic heating for the duration of the treatment cycle, once the therapeutic temperature is reached.

Both devices provide instructions and warnings for variable depth heating.

The Intelect User Manual directs: "The Electrode-Skin Distance (ESD) must be small for surface warming and large for depth warming. A larger Electrode-Skin Distance (ESD) is necessary for patients with a thick layer of subcutaneous fat in order to achieve the necessary warming of deep-lying tissue."

The Biofusionary Bebe provides protocols in the User Manual that aid the operator in applying heat to the tissues appropriately.

#### Safety Precautions:

Patient treatment criteria and warnings are provided in the User Manuals of both the Intelect and Biofusionary Bebe to assure safe and effective treatment:

The Intelect manual recommends four different dosage levels for operation using patient feedback to accommodate patients with different pain sensation levels, the lowest level being used for those who cannot sense pain.

The Biofusionary Bebe requires user feedback to determine the appropriate conditions of treatment. The User Manual provides warnings and protocols to address patients with little or no sensation of pain.

Both devices rely on patient feedback to avoid the risk of excessive warming, and both devices provide similar warnings, cautions and contraindications in their User Manuals.
