Intended Use
The Indigo 830e LaserOptic ™ Treatment System is intended to be used in the contact mode to photocoagulate, vaporize/ablate soft tissue (muscle, connective tissue, organ), and in the contact or non-contact mode for cutting, excision, incision, and coagulation of soft tissue in both open or closed surgical procedures. The Índigo 830e LaserOptic™ Treatment System with Diffuser-Tip™ Fiberoptic is indicated for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH) in men over the age of 50 with prostates with median and/or lateral lobes ranging in total volume from 20-85 cc and for general surgery, general urological and gastroenterological procedures including the incision, excision, and ablation of soft tissues; and coagulative necrosis and interstitial laser coagulation of soft tissues.
Device Description
The Índigo Diffuser- Tip™ Fiberoptic is a sterile, single-use, disposable fiberoptic which is 3 meters in length with a light-diffusing section at the distal tip. The device is designed to deliver energy from the Indigo Model 830e diode laser only and bears a unique connector for coupling to the 830e laser at the proximal end. Modifications have been made to increase the resistance to breakage of the fiberoptic and improve the manufacturability of the device. None of the changes affect the function, intended use, or overall design of the fiberoptic or of the Indigo LaserOpticTM Treatment System.
More Information

No
The document describes a laser treatment system and fiberoptic, focusing on its physical characteristics, intended use for tissue treatment, and performance studies related to temperature profiles and lesion size. There is no mention of AI, ML, image processing, or any data-driven decision-making components.

Yes

The device is intended for the photocoagulation, vaporization/ablation of soft tissue, cutting, excision, incision, and coagulation of soft tissue in surgical procedures, and specifically for the treatment of symptoms of benign prostatic hyperplasia (BPH), which are therapeutic interventions.

No
Explanation: The device is described as a "Treatment System" intended to "photocoagulate, vaporize/ablate soft tissue," "cut, incise, and coagulate soft tissue," and for "coagulative necrosis and interstitial laser coagulation of soft tissues." These are all therapeutic actions, not diagnostic ones.

No

The device description explicitly mentions a "sterile, single-use, disposable fiberoptic" which is a physical hardware component designed to deliver energy from a laser. This is not a software-only device.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical treatment system that uses laser energy to directly interact with and modify soft tissue within the body (photocoagulation, vaporization/ablation, cutting, excision, incision, coagulation). This is an in vivo procedure.
  • Device Description: The device description details a fiberoptic designed to deliver laser energy for these surgical procedures.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, urine, tissue samples, etc.) outside of the body to provide information for diagnosis, monitoring, or screening.

IVD devices are used to perform tests on samples taken from the body, while this device is used to directly treat tissue within the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Testing was performed in order to compare the modified Diffuser-Tip™ Fiberoptic with the existing fiberoptic for equivalence of the tissue temperature profiles and the resulting lesion size. The lesion size, temperature accuracy, internal heating of the fiber, time to reach operating temperature, fiber intensity profile, and total energy delivered were measured and compared. The results indicated that the modified Diffuser-Tip™ Fiberoptic had an equivalent tissue temperature profile, and that the lesion size created by the modified fiberoptic is equivalent to the lesion size created by the current Diffuser-Tip™ Fiberoptic. A reliability assessment was conducted to evaluate the robustness and resistance to breakage of the modified fiberoptic as compared to the current Diffuser-Tip™ Fiberoptic. Results indicated a significant improvement.

Comparison of Technological Characteristics: The technical and functional characteristics of the modified Diffuser-Tip™ Fiberoptic are essentially identical to the existing Diffuser-Tip™ Fiberoptic. The modifications to the components incorporated in the design are refinements to the manufacturing process and to the design which do not represent technological changes. The laser source is the Model 830e diode laser in both cases and the output and resulting lesion size have not changed.

Nonclinical Tests: Testing was performed in order to compare the modified Diffuser-Tip™ Fiberoptic with the existing fiberoptic for equivalence of the tissue temperature profiles and the resulting lesion size. The lesion size, temperature accuracy, internal heating of the fiber, time to reach operating temperature, fiber intensity profile, and total energy delivered were measured and compared.

Dear Ms. Hughes:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
