• Is the MS-139 Electronic Muscle Stimulator designed for single-use or can it be reused across multiple patients or sessions?

  The MS-139 is explicitly labeled as a reusable medical instrument, meaning it is intended for repeated use without requiring sterilization between sessions. Since it does not require sterilization, it is suitable for both clinical and home settings where trained professionals or patients under guidance may operate it over time.

• What types of clinical settings or patient needs is this device primarily intended to support, based on its FDA clearance?

  The MS-139 received FDA 510(k) clearance under the Physical Medicine advisory committee, indicating its primary use is for rehabilitation, pain management, or muscle strengthening through controlled electrical stimulation. It is not restricted to specific MRI environments or patient sizes, making it versatile for general therapeutic applications.

• How is the MS-139 supplied, and are there any special handling requirements for storage or maintenance?

  The MS-139 is supplied as a reusable device, so no sterilization is required between uses. While the device data does not specify storage conditions, typical reusable medical instruments should be stored in a clean, dry environment away from direct sunlight or extreme temperatures. Maintenance instructions are not provided in the data, but proper care—such as cleaning per manufacturer guidelines—would be necessary to ensure safe, prolonged use.

• Does the MS-139 come in different sizes or models, or is it a single-unit device?

  The provided data does not mention any variations in size or model numbers for the MS-139, suggesting it is likely offered as a single-unit device without modular or adjustable components. If specific configurations are needed, they would need to be confirmed directly with Electro Med Supply, Inc.
