The ClearCount Medical Solutions SmartWand-DTX™ System is indicated for use in counting and displaying the number of RFID-tagged surgical sponges, laparatomy sponge, and towels detected by the device and providing a noninvasive means of locating retained RFID-tagged surgical sponges, towels, and other tagged items within a surgical site.
The SmartWand-DTX™ System is based on radio frequency identification (RFID) tags. The RFID tags are provided to manufacturers of surgical disposables for inclusion into their surgical sponges, laparotomy pads and surgical towels. The disposable manufacturer permanently attaches the RFID tags to the gauze or fabric of the disposables. The tags are then programmed to contain information about the type and number of disposables in the package. This allows the sponges, pads, and towels to be individually recognized by an RFID reader. The RFID tag function is the same as that for the SmartSponge Plus System.
The SmartWand-DTX is a device comprised of a handheld scanning antenna that is attached to an electronics box that contains an RFID reader and supporting electronics. Integrated RFID technology allows the capture of the information coded on the unique RFID tags in the sponges, pads and towels. When the tagged sponges, pads, and towels are detected by the scanning wand, the device displays the type and number of each type of item that is detected. The system recognizes RFID-tagged items that may be inside the surgical site.

Study Information:
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated. The text mentions "simulated use" and "verification and validation testing," but no specific number of cases or items tested is provided.
- Data Provenance: The testing was "Non-Clinical," conducted in a "laboratory setting." There is no mention of human subject data, retrospective, or prospective studies in a clinical environment.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Not explicitly stated. Given the non-clinical, laboratory setting, ground truth would likely refer to the known presence and location of RFID tags placed by the testing personnel rather than expert clinical consensus.
4. Adjudication Method for the Test Set
- Not applicable/Not stated. Since the testing was non-clinical and involved detecting pre-placed tags, a formal adjudication method by experts (like 2+1 or 3+1) is not relevant in this context. The "ground truth" would be the known, objective presence/absence/location of the tags.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
- No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This device is a standalone detection system, not an AI-assisted diagnostic tool for human readers. It's intended to replace manual counting and provide localization, not enhance human interpretation of images. Consequently, there's no mention of "human readers" or "AI assistance."
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Yes, a standalone performance assessment was conducted. The device (SmartWand-DTX System) is described as "algorithm only without human-in-the-loop performance" in terms of its core detection and counting function. It directly detects RFID tags and displays information. The testing involved the device's ability to "properly locating all tags" in simulated use.
7. The Type of Ground Truth Used
- The ground truth in the non-clinical testing was based on the known, objective presence and location of RFID-tagged items placed by the testing personnel in a simulated environment. It was not expert consensus, pathology, or outcomes data, as those are relevant to clinical diagnostic devices.
8. The Sample Size for the Training Set
- Not specified. The document primarily discusses verification and validation testing, not the training of a machine learning algorithm. While the device contains a "proprietary software operating on a microcontroller unit," specific "training set" data for an AI model is not detailed. The system is based on RFID technology and reading unique identifying numbers, which implies a more deterministic operating principle rather than a continuously learning AI model that requires a discrete training set.
9. How the Ground Truth for the Training Set Was Established
- Not applicable/Not specified as a distinct "training set" in the context of an AI algorithm. The device relies on reading pre-programmed RFID tags. If there was any internal calibration or refinement, it's not described in terms of a formal training set.

- The SmartWand-DTX™ System is based on radio frequency Device Description: identification (RFID) tags. The RFID tags are provided to manufacturers of surgical disposables for inclusion into their surgical sponges, laparotomy pads and surgical towels. The disposable manufacturer permanently attaches the RFID tags to the gauze or fabric of the disposables. The tags are then programmed to contain information about the type and number of disposables in the package. This allows the sponges, pads, and towels to be individually recognized by an RFID reader. The RFID tag function is the same as that for the SmartSponge Plus System.
The SmartWand-DTX is a device comprised of a handheld scanning antenna that is attached to an electronics box that contains an RFID reader and supporting electronics. Integrated RFID technology allows the capture of the information coded on the unique RFID tags in the sponges, pads and towels. When the tagged sponges, pads, and towels are detected by the scanning wand, the device displays the type and number of each type of item that is detected. The system recognizes RFID-tagged items that may be inside the surgical site.

A SmartTag is a disposable RFID tag that is approximately the size of a business card. Like the RFID-tagged sponges, the SmartTags contain unique identifying numbers and are distinguishable by the system software. The SmartTag is placed on the operating room table before the patient is brought into the room and is covered by the standard sheets or drapes used in surgery, thus not making contact with the patient. The SmartTag provides feedback to the user that the detection wand is being held close enough to the patient to ensure proper scanning.
Intended Use: The ClearCount Medical Solutions SmartWand-DTX System is indicated for use in counting and displaying the number of RFIDtagged surgical sponges, laparatomy sponges, and towels detected by the device and providing a non-invasive means of locating retained RFID-tagged surgical sponges, towels, and other tagged items within a surgical site.
The indications are a subset of those of the ClearCount SmartSponge® Plus predicate device in that it provides a noninvasive means of identifying retained RFID-tagged surgical sponges, towels, and other tagged items within a surgical site. This indication is also consistent with the RF Surgical Systems Detection System.
The ClearCount Medical Solutions SmartWand-DTX System, like the SmartSponge Plus System, relies on permanently affixed radiofrequency identification (RFID) tags to convey unique identification information about each item, unlike the RF Surgical Detection System which uses resonant frequency tags which creates a field disturbance that may indicate the presence of an item.
The addition of unique identifying information allows the SmartWand-DTX to identify specific attributes, such as the type and quantity of sponges, in an identical manner to the ClearCount SmartSponge Plus predicate device. The ability to distinguish tags uniquely also enables the operation of the SmartTag for aiding in the effective scanning of the surgical site.
Technological Characteristics:
The RFID tags attached to surgical disposables identifies each item to the SmartWand-DTX which reads the tag information with an RFID reader controlled by proprietary software operating on a microcontroller unit. The wand can read the tag through a human body. The device software uses the scanned information to display the type and number of each type of item detected during a scan.
{2}------------------------------------------------
The ClearCount SmartWand-DTX System, like the SmartSponge Plus predicate, has a tethered detection wand that uses the same power and control system and same display as the SmartSponge Plus detection wand. The detection wand is used in a similar manner to the RF Surgical Detection System. However, the ClearCount detection wand is provided as a permanent device rather than a single-use disposable. A disposable sterile sheath will be provided for covering the detection wand and the portion of the wand cable that may contact the sterile field.
The SmartWand-DTX System, like the SmartSponge Plus System predicate device, uses RFID technology to communicate unique identification data from tagged items to the reader. This technology is also similar to that of the RF Surgical Detection System predicate, (K062642). Both systems rely on passive tags, which hold no electric charge and remain inactive until energized by a reader in close proximity. RF Surgical tags resonate when excited by a specific radio frequency, causing a specific frequency response which is detected by the RF Surgical Detection Wand. The presence of a resonant tag then alerts the system that a tagged item is within the specified range of the RF Surgical Wand. The ClearCount System also uses a specific radio frequency which causes its passive tags to resonate when within the range of the ClearCount Wand. In the ClearCount System, these tags contain unique identifying information which is stored and used by the device to detect the presence of a tagged item as well as provide descriptive information about the detected items.
The system has also been designed to meet the following electrical safety standards and electromagnetic compatibility standards:
UL 60601-1 Medical Electrical Equipment - Part 1: General Requirements for Safety
IEC 60601-1-2 (Edition 2.1 - 2004-11) Medical Electrical Equipment - Part 1-2: General Requirements for Safety -Collateral Standard: Electromagnetic Compatibility -Requirements and Tests
Non-Clinical
Non-Clinical testing included simulated use of the device in a Performance Data: laboratory setting. The SmartWand-DTX uses the same RFID technology and hardware as the SmartSponge Plus. The performance of the SmartWand-DTX is actually enhanced over the SmartSponge Plus scanning wand in that the wand is pre-tuned
{3}------------------------------------------------
thereby making the software algorithm less complex such that the scanning speed is increased. The SmartWand-DTX System performed as intended in the verification and validation testing. 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.
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Conclusions: The data and information demonstrates that the ClearCount SmartWand-DTX™ System provides an added measure of safety and effectiveness to the current methods of gauze and sponge detection presently used in the surgical environments.
