No
The device description focuses on laser technology, operation modes, and hardware components. There is no mention of AI, ML, image processing, or data-driven decision-making.
Yes
The device is marketed for "Laser Therapy System" and its indications for use (incision, excision, vaporization, ablation, coagulation) are therapeutic procedures.
No
The device description clearly states it is a "surgical device" used for "surgical and cosmetic procedures" and for "dispose tissue and lesion" through "Incision, Excision, Vaporization, Ablation, Coagulation." These are all therapeutic actions, not diagnostic ones.
No
The device description clearly outlines hardware components such as a semiconductor diode laser source, flexible fiber, handpiece, footswitch, and semiconductor refrigeration technology. It is a physical surgical device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states "intraoral use for the following soft tissue applications: Incision, Excision, Vaporization, Ablation, Coagulation." These are all surgical procedures performed directly on the patient's tissue.
- Device Description: The description details a surgical laser device that delivers energy to tissue for cutting, removing, or modifying it. It describes the laser source, power delivery, and operation modes, all consistent with a surgical tool.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (like blood, urine, or tissue) to diagnose a disease or condition. IVDs are designed for testing samples outside the body (in vitro).
Therefore, the DenLase Diode Laser Therapy System is a surgical device, not an In Vitro Diagnostic device.

Device Description
The DenLase is a surgical device designed with compactness, portability, reliability and user-friendliness. It provides the operator with a tool for surgical and cosmetic procedures on oral soft tissue. The Denlase utilizes a semiconductor diode with invisible infrared radiation as a laser source (810nm or 980nm). The laser power is delivered to the treatment area via a flexible fiber, which has a handpiece. The emission laser is activated by a footswitch.
The Denlase adopts advanced semiconductor lasers (AIGAAs) and semiconductor refrigeration technology. By laser sent out by optical fiber, it can fast and accurately dispose tissue and lesion. The device includes three operation modes as continuous. single pulse and continuous pulse, and each operation mode is adjustable respectively by three parameter of emitting power, pulse width and pulse interval. The user can save total five groups of operation mode parameter combination under different mode.
