The OneMark Breast Localization Marker is intended to be placed percutaneously in soft tissue (>30 days) to mark a biopsy site or soft tissue intended for surgical removal. Using imaging guidance (such as ultrasound, MRI, or radiography) or detection imaging (OneMark Detection Imaging System), the OneMark Breast Localization Marker is located and may be surgically removed with the target tissue. The OneMark Detection Imaging System is intended only for the detection of the OneMark Breast Localization Marker.

Device Description

OneMark is an integrated localization system consisting of the OneMark Detection Imaging System and the OneMark Breast Localization Marker preloaded in an injector device. The OneMark Detection Imaging System is an ultrasound-based intraoperative inspection tool used by clinicians to localize the OneMark Breast Localization Marker, a hydrogel pellet implanted in tissue to mark the site of a lesion. The primary goal of the system is to aid a surgeon in resection of a marked cancer lesion. The system may be used to inspect the marked tissue in all typical workflow situations from initial implant post-biopsy through resection and ex-vivo specimen review.

AI/ML Overview

This FDA 510(k) summary for the OneMark Breast Localization Marker and OneMark Detection Imaging System does not contain information about specific acceptance criteria, a study that proves the device meets those criteria, or details regarding test sets, ground truth establishment, or clinical studies (MRMC or standalone algorithm performance).

The document primarily focuses on non-clinical testing to demonstrate substantial equivalence to predicate devices. It lists various non-clinical tests performed but does not provide specific performance metrics, acceptance criteria, or results from these tests beyond stating that they indicate substantial equivalence.

Therefore, the requested information cannot be extracted from the provided text. The document does not describe:

A table of acceptance criteria and the reported device performance: No specific performance metrics or acceptance criteria are mentioned for the device's function (e.g., accuracy of localization, sensitivity/specificity).
Sample size used for the test set and the data provenance: No information about a test set, its size, or origin (country, retrospective/prospective).
Number of experts used to establish the ground truth for the test set and the qualifications: No details on expert involvement or ground truth establishment.
Adjudication method for the test set: Not applicable as no test set data is presented.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, or the effect size of human readers improving with AI vs. without AI assistance: No MRMC or clinical effectiveness study is described. The device is a localization marker and detection system, not an AI diagnostic tool that assists human readers in interpreting medical images.
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable as the "OneMark Detection Imaging System" is an ultrasound-based intraoperative inspection tool designed for clinical use, implying human operation and interpretation. The "algorithm" mentioned (processing phase shift into a vibrant color image) is part of a system used by clinicians, not a standalone diagnostic AI.
The type of ground truth used: No ground truth for an efficacy study is described.
The sample size for the training set: No information on a training set.
How the ground truth for the training set was established: Not applicable.

The "Non-clinical performance bench testing" is listed, but no details about its methodology, specific acceptance criteria, or results are provided. The "GLP animal testing" is also mentioned, but again, without specific performance data relevant to the device's localization accuracy or effectiveness.

DEVICE DESCRIPTION

INDICATIONS FOR USE

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

View Point Medical believes that OneMark is substantially equivalent to the predicate devices based on the information summarized here:

The subject device has the same intended use as the primary predicate. Both the subject device and the primary predicate are intended as an aid in resecting a marked cancer lesion by providing a marker to be implanted in the suspected tissue and a detection system for the implanted marker during resection surgery.

The subject device has a similar design as the primary predicate. Both the subject device and the primary predicate feature similar components to achieve the intended effect: a marker, a marker delivery system, a handpiece/probe and a display console. The subject device has similar materials for the delivery system, the handpiece/probe and the display console components as the primary predicate device (e.g., molded plastics, stainless steel).

The main technological differences of OneMark, as compared to the primary predicate, are:

. Type of energy/Principle of operation. OneMark Breast Marker is a passive implant that includes silica microspheres as compared to a micro-impulse radar (SAVI Scout System). The silica microspheres do not emit any form of energy. Instead, they reflect a phase shift when exposed to ultrasound energy which can be processed into a vibrant color image to visualize the marker's location. The amount of ultrasound energy necessary for the OneMark Detection System to locate the OneMark Breast Marker is similar to the amount of ultrasound energy necessary to locate the reference predicate marker

{5}------------------------------------------------

(SignalMark Breast Marker). This difference with the primary predicate does not introduce any new or different questions of safety and effectiveness.

Marker materials. Materials for the marker component of the subject device are different than for the primary predicate device but are similar to the materials for the reference devices (SignalMark Breast Marker, HydroMARK Breast Biopsy Site Marker). Materials for the OneMark Breast Marker have undergone testing to ensure the marker is as safe and effective as the predicate markers (SAVI Scout Reflector, SignalMark Breast Marker, HydroMARK Breast Biopsy Site Marker).
. Marker dimensions. The marker for the subject device is smaller in size than the marker for the primary predicate device, but its dimensions are similar to the dimensions of the reference predicate marker (HydroMARK Breast Biopsy Site Marker). This difference with the primary predicate does not introduce any new or different questions of safety and effectiveness.
. Marker sterilization. Gamma radiation was used to achieve a SAL of 10° for the Marker, compared to ethylene oxide for the primary predicate. Gamma radiation method was also used for the reference device (SignalMark Breast Marker).

These technological differences have undergone testing to ensure the subject device is as safe and effective as the predicate device.

SUMMARY OF NON-CLINICAL TESTING

The following tests were performed to demonstrate safety based on current industry standards:

Biocompatibility testing per ISO 10993-1
Gamma radiation sterilization validation per ANSI/AAMI/ISO 11137-2
Shelf-life validation testing
Packaging validation testing per ISTA 2A-2011 and ASTM F2096-11
Software testing per IEC 62304
Electrical safety testing per IEC 60601-1 and IEC 60601-2-37
EMC testing per IEC 60601-1-2
Non-clinical performance bench testing
GLP animal testing

The results of these tests indicate that OneMark is substantially equivalent to the predicate devices.

CONCLUSION

Based on the testing performed, including sterilization, packaging and shelf-life validation, biocompatibility, software validation, electrical safety, EMC testing, non-clinical performance bench testing, and GLP animal testing, it can be concluded that the subject device (OneMark Biopsy Site Marker — K241762) does not raise new issues of safety or effectiveness compared to the predicate device (Cianna Medical Scout Reflector and Scout System – K181007). The indications for use, technological characteristics, and performance characteristics for the proposed OneMark are assessed to be substantially equivalent to the predicate device.
