Dear Vince Chen:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Comparison to Predicate: The Indications for Use of the subject device are comparable to those of the predicate device. The main difference is that the predicate device specifically calls out use of the device with a particular ICG product (SPY AGENT GREEN), while the indications of use for the subject device denote use of ICG consistent with its approved label. It is also noted that the intended use population for the subject device includes adults only, while that of the predicate device includes adults and pediatrics. These differences do not raise concerns of safety or effectiveness.
# VI. Comparison of Technological Characteristics with the Predicate Device
The subject device (SIM 1000H) and the predicate device (SPY-PHI) share the same fundamental technological characteristics. Both include a handheld camera and a processing unit, use near-infrared excitation with indocyanine green (ICG) for fluorescence imaging, and provide white-light illumination for visible imaging. Both capture fluorescence and reflected signals, process them in real time, and output intraoperative images.

## VIII. Conclusions
The SURGIMAGE SIM 1000H Fluorescence Imaging Platform is the same or similar in intended use and fundamental technological characteristics to the predicate device. The non-clinical data support the safety of the device, and the comparative performance testing demonstrates that the SIM 1000H performs comparably to the predicate device. The combination of these data demonstrates that the subject device is the same or similar, with respect to safety and effectiveness, to the legally marketed predicate device.
