Ultrasound therapy is available from the HF54 and indicated for: Applying therapeutic deep heat within body tissues for the treatment of selected chronic and sub-chronic medical conditions such as: Relief of pain; joint contractures. This can be done using One or two ultrasound applicators. The second ultrasound applicator is optional. Ultrasound therapy, either alone or in combination with interferential therapy or premodulated therapy can be used in a scanned manner (where the therapist moves the applicator) or for specific treatment areas identified in the operator's manual, the applicator can be used in a hands-free manner (where the applicator remains stationary). An Infrared Therapy Probe is available as an optional accessory (HF023) for use with the Hill Laboratories HF54 Combination Ultrasound Interferential and premodulated stimulation system or for stand-alone use with an optional external medical grade, isolated power supply. It is used to provide topical heating for: Temporary increases in local blood flow and circulation; Temporary relief of minor muscle and joint aches; Temporary relief of pain and stiffness; Relaxation of muscles; Temporary relief (or relaxation) of muscle spasms; Temporary relief of minor pain and stiffness associated with arthritis. ## Device Story HF54 is a combination system providing ultrasound, interferential, and premodulated electrical stimulation; optional infrared probe (HF023) provides topical heating. Device used in clinical settings by qualified therapists. Ultrasound applicators (one or two) deliver therapeutic deep heat; can be operated in manual scanned mode or stationary hands-free mode. System monitors treatment parameters; operator must remain present to ensure patient safety and prevent overheating. Output affects clinical decision-making by providing physical therapy modalities for pain management and tissue heating. Benefits include non-invasive pain relief and muscle relaxation. ## Clinical Evidence Bench testing only. Thermal measurements confirmed that ultrasound applicator surface temperature does not exceed 45 °C during stationary use. Thermal index calculations and measurements verified that tissue and bone temperatures remain below 45 °C at intensities ≤ 10W. No clinical data provided. ## Technological Characteristics Combination system for ultrasonic diathermy, interferential/premodulated stimulation, and infrared therapy. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-5, and IEC 60601-2-10. Ultrasound output is pulsed. Features optional hands-free stationary ultrasound application. Materials and display parameters are identical to predicate K062256. ## Regulatory Identification An ultrasonic diathermy for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body ultrasonic energy at a frequency beyond 20 kilohertz 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. ## Predicate Devices - HF 54 ([K062256](/device/K062256.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Standards #### 11.1 Mandatory Standards 21 CFR 1050.10 is applicable to therapeutic ultrasound. The HF54 Combination Ultrasound Interferential and Premodulated Stimulation System with ontional hands-free operation complies with this mandatory standard. #### 11.2 Consensus Standards The HF54 Combination Ultrasound Interferential and Premodulated Stimulation System with optional hands-free operation is designed to comply with the following Consensus Standards: | STANDARD NO. | TITLE | |----------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------| | IEC 60601-1 +A1, +A2 | Medical Electrical Equipment- Part 1: General Requirements for

Name | Manufacturer | Class | |---------------|---------------------------------------|-------------------|-------| | K062256 | HF 54 | Hill Laboratories | 2 | {3}------------------------------------------------ #### Substantial Equivalence (SE) Rationale 12.1 ## 12.1.1 Technology The HF54 with optional hands-free operation offers the same electrical stimulation, ultrasonic therapy and/or combination of the two and shares the same characteristics including waveforms, operating frequencies and the same use in physical medicine and neurology as the predicate device. The device with its proposed extended indications for use is intended to be used only by a qualified therapist. ## 12.1.2 Standards The ultrasound output and electrical stimulation currents are consistent with FDA guidance and international standards. The new device is in compliance to the same standards. ## 12.1.3 Materials The materials used in construction of the device and the method of information display are identical. The measured parameters for the proposed HF54 are the identical to those displayed on the device cleared under K062256. The software has not been changed from the cleared device. ## 12.1.4 Risk Analysis The expanded indications for use (stationary ultrasound) needed a review of the risks posed by a stationary technique. The primary risks were identified as: - a) Temperatures in tissues above 45 °C - b) Temperature rise in bone - Standing waves c) - d) Self-heating of the ultrasound applicator - The patient falling asleep during hands-free operation possibly leading to e) overheating of tissues. #### Temperatures in Tissues and In Bone 12.1.4.1 From Measurement and Thermal Index Calculations, it was shown that with an intensity of ≤ 10W, the temperature of Tissue or Bone would not rise above 45 °C when used as directed. See Attachment C-1. There is no new safety issue. #### 12.1.4.2 Standing Waves The ultrasound output is pulsed and will not support standing waves. There is no new safety issue. #### 12.1.4.3 Self Heating of the Ultrasound Applicator Measurements made during the original submission for the HF54 included thermal measurements of the ultrasound applicator surface. The tests demonstrated that the applicator surface temperature did not exceed 45 °C when stationary, over the whole treatment time. Measurements were made at equal distances across the surface of the treatment surface. There is no new safety issue. HF54 With Optional Hands-free operation {4}------------------------------------------------ #### Patient falling asleep during treatment 12.1.4.4 The operator's manual requires that the operator remain in the same area as the patient and must monitor the patient to ensure that the patient has not fallen asleep. There are no new treatment modes, identical circuitry and software are used. The changes therefore do not change the effectiveness of the device. ## 12.2 Conclusion The proposed HF54 with Optional Hands-free operation when used as directed in the operator's manual presents no new safety or effectiveness concerns and is Substantially Equivalent to the current version of the HF54 cleared under K062256. {5}------------------------------------------------ Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
