No
The summary describes a fluorescence imaging accessory for a surgical microscope that visualizes blood flow using a fluorescent agent. There is no mention of AI, ML, image processing beyond basic visualization, or any data processing that would suggest the use of such technologies.
No
The device is used for "viewing intra-operative blood flow" and "depicts the distribution of the infra-red dye," indicating it is a diagnostic or imaging accessory, not a therapeutic device.
Yes
Explanation: The device allows for viewing of intra-operative blood flow to "depict the distribution of the infra-red dye in the patient's blood vessels during the operation (fluorescence video angiography)," which provides visual information to the surgeon to help diagnose blood flow issues or confirm successful bypass grafts.
No
The device is described as an "accessory to the Leica surgical microscopes" and allows the microscope to "produce excitation light and resolve fluorescence light." This clearly indicates the presence of hardware components that interact with the physical world (light generation and detection), not just software processing.
Based on the provided information, the Leica FL800 is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The Leica FL800 is used to visualize blood flow within the patient's body during surgery. It does not analyze samples taken from the patient.
- The intended use describes direct visualization during surgical procedures. The device is an accessory to a surgical microscope and is used for real-time viewing of blood flow in vivo.
- The device description focuses on generating and resolving fluorescence light from a fluorescent agent within the patient. This is an in-vivo imaging technique, not an in-vitro diagnostic test.
Therefore, the Leica FL800 falls under the category of an in-vivo imaging device used during surgery, not an IVD.

Dear Ms. Conway-Myers:
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 (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. 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

Standards Used in Demonstrating Conformance
The Leica FL800 device is an accessory to the Leica surgical microscopes and as an accessory was not individually tested to any recognized standard. However, this accessary was tested in combination with the Leica surgical microscopes to demonstrate that it did not neqatively impact the safety and effectiveness of the Surgical Microscope.
For Electromagnetic Compatibility (EMC) the Leica FL800 ULT has been tested and showed conformance to standard IEC 60601-1-2 Edition 3:2007.
For Electrical Safety the Leica FL800 ULT has been tested and showed conformance to standard IEC 60601-1 Edition 3:2005.

Conclusion
The modification of the Leica FL800 (variant) consists of the relocation of this accessory from an external configuration to an internal configuration which services 2 distinct advantages:
- It decreases the likelihood of any external disturbances to the Leica FL800 either by the surgeon . or the operating room staff.
- . The aesthetically pleasing design makes the device more ergonomic which is a value to the surgeon.
There is no alteration to either the intended use or the device's fundamental scientific technology and for this reason, Leica Microsystems seeks a Special 510k for the clearance of this device.
