No
The device description lists standard medical device components and a personal computer running Windows XP, with no mention of AI/ML algorithms or capabilities. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
Yes
The device is indicated for the treatment of fibroadenomas and for general surgery procedures involving incision, excision, ablation of soft tissues, and coagulative necrosis, which are all therapeutic interventions.
No
This device is described as a "Therapy System" indicated for the "treatment" of fibroadenomas and for general surgery "procedures including incision, excision and ablation of soft tissues". Its components and described functions, such as laser sources and infusion pumps, are consistent with therapeutic interventions rather than diagnostic processes.
No
The device description clearly lists multiple hardware components including laser probes, temperature probes, a syringe infusion pump, a laser diode source, and a storage cart, in addition to a personal computer.
Based on the provided information, the Kelsey Interstitial Laser Therapy System is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly describes a therapeutic procedure performed directly on the patient's body (treatment of fibroadenomas, general surgery procedures, soft tissue ablation and coagulation). IVDs are used to examine specimens taken from the body (like blood, urine, tissue samples) to provide information about a patient's health status.
- Device Description: The components listed are all designed for delivering energy (laser) and monitoring temperature within the body, or for supporting this process. There are no components mentioned that would be used for analyzing biological samples.
- Performance Studies: The performance studies described focus on the safety and effectiveness of the device for tissue ablation, which is a therapeutic outcome, not a diagnostic one.
Therefore, the Kelsey Interstitial Laser Therapy System is a therapeutic device, not an IVD.

Dear Mr. Ketteridge:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
