The description focuses on a system using magnetic fields and passive tags for detection, with no mention of AI/ML terms, image processing, or data-driven learning processes.
No.
The device is described as a detection system for locating retained surgical items, not for providing therapy or treatment.
No
The device's stated purpose is to locate retained surgical sponges and other tagged items within a surgical site. This is a detection function, not a diagnostic one. A diagnostic device would typically aid in identifying a disease, condition, or the nature of an existing problem, often by analyzing biological samples or imaging internal structures for medical conditions. This device identifies the presence of an object, not a medical condition.
No
The device description clearly outlines multiple hardware components: a Power/Control Console, a Transponder/Tag, and a Detection Wand. While software is mentioned as being validated, it is part of a larger system that includes physical hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to locate retained surgical items within a surgical site. This is a direct interaction with the patient's body (in vivo), not the examination of specimens derived from the human body (in vitro).
- Device Description: The components described (console, transponder/tag, detection wand) are designed for physical interaction with the surgical site and the tagged items within it.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, urine, etc.), using reagents, or providing diagnostic information based on the analysis of such samples.
The device is clearly designed for a surgical setting to aid in preventing retained surgical items, which is an in-vivo application.

Device Description
The RF Surgical Systems Inc. Detection System consists of:
- The Power/Control Console contains the electronics that power and control the detector/scanner. The console also includes the user interface for system operation and communication of the system status, operation and alarms to the user.
- The Transponder/Tag is a single use electrically passive device that is designed to radiate a magnetic signature when stimulated by magnetic impulses from the detector/scanner. The tag does not store or communicate any information or unique code and is to be mechanically attached to guaze sponges at the manufacturing site and processed as part of the item
- The Detection Wand is a transceiver type antenna designed to stimulate the transponder tag assembly with magnetic impulses and then detect the resultant magnetic signature from the tag. The Power/Control Console provides the power and control to the detection scanner. The detection scanner is intended and designed to be a single-use disposable device and will be supplied in a sterile condition as it will enter the surgical field.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical testing included simulated use in patient models that represented worst case biological situations as well as manufacturing process situations and in all cases the RF Surgical Detection System performed as intended. Animal studies using large swine species further substantiate the satisfactory performance of the detection system. Biocompatibility of the transponder tag was illustrated and is comparable to the commercially available predicates. The validated software functioned as intended under simulated use, properly locating all tags. This testing supports a determination of substantial equivalence to products and technologies previously cleared by FDA.

(a)
Identification. A surgical sponge scale is a nonelectrically powered device used to weigh surgical sponges that have been used to absorb blood during surgery so that, by comparison with the known dry weight of the sponges, an estimate may be made of the blood lost by the patient during surgery.(b)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in § 880.9. The device also is exempt from the current good manufacturing practice requirements of the quality system regulation in part 820 of this chapter, with the exception of § 820.180, with respect to general requirements concerning records, and § 820.198, with respect to complaint files.

Intended Use: The RF Surgical Systems Inc. Detection System is intended to provide a noninvasive means of locating retained surgical sponges, gauze and other tagged items within a surgical site. It is to be employed as an adjunctive detection method to current surgical sponge and gauze counting systems and methods
Technological
The indications are similar those of the predicate devices i.e. "for efficient counting and containment of lap sponges, and for constant visibility for assessing blood loss and counting of sponges."
Characteristics: The RF Surgical Systems Inc. Detection System is analogous to the predicate devices. The Transponder Tag identifies the sponge or gauze to the detection system via a specific radio frequency signal through the single use detection wand. The detection wand can read the tag signal through blood, bodily fluids and the body wall. The 3 element detection system is designed to detect tagged objects(s) within a minimum range of 16" from the detector aperture surface into a patient of average size Tags outside of the patient and more than 36" outside of the scan area must not result in false positives. The console is a durable electro-mechanical assembly that is powered by standard line voltage: 120V. 60Hz and has been designed to work in standard operating rooms or other clinical environments. The console has also been designed to meet the following electrical safety standards and electromagnetic compatibility standards:
IEC 60601-1 Medical Electrical Equipment - Part 1: General Requirements for Safety
IEC 60601-1-2 (Second Edition, 2001) Medical Electrical Equipment - Part 1: General Requirements for Safety; Electromagnetic Compatibility -Requirements and Tests
The wand is a transceiver type antenna designed to stimulate the transponder tag assembly with magnetic impulses and then detect the resultant magnetic signature from the tag. The Power/Control Console provides the power and control to the detection scanner.The detection scanner is intended and designed to be a single-use disposable device and will be supplied in a sterile condition as it will enter the surgical field. The Scanner consists of two-part plastic handle that encloses a wire loop antenna, a capacitor and a fuse. The antenna consists of and arrangement of multiple turns of a copper magnet wire with a specific diameter. The copper magnet wire is insulated with an enamel coating. An electrical fuse and series capacitor is wired between the ends of the antenna winding. The antenna is attached to a standard RG-58 50Ω coaxial cable with a standard 50Ω BNC Connector.
The tag is an electrically passive device that is designed to radiate a magnetic signature when stimulated by magnetic impulses from the detector/scanner. The tag does not store or communicate any information or unique code, rather it responds at its resonant frequency, which by design falls within a specific band of operation and which the detection system is designed to identify . All tags resonate at the same frequency within the band of operation, and only the presence of a tag is indicated even should more than one be present.
