Intended Use
The VariSource iX is indicated, in the treatment of both benign and malignant disease, for both curative and palliative intent, in the delivery of remote-controlled high dose-rate Brachytherapy for conditions anywhere in the body when brachytherapy treatment is indicated.
Device Description
The VariSource iX Series High Dose Rate Afterloader system is a computer controlled remote electro/mechanical system used for medical purposes, for placing a NiTiNol wire incorporating an irradiated iridium seed internally or close by, a malignant tumor or tumor bed in a practice known as brachytherapy. The device has up to 20 channels for treatment.
More Information

Not Found

No
The summary does not mention AI, ML, or related terms, and the device description focuses on electro/mechanical control for brachytherapy.

Yes
The device is used for the "treatment of both benign and malignant disease" and "delivery of remote-controlled high dose-rate Brachytherapy," which are therapeutic applications.

No

The device description indicates it is used for treatment delivery (brachytherapy), not for diagnosing conditions.

No

The device description explicitly states it is a "computer controlled remote electro/mechanical system" and mentions placing a wire and seed, indicating significant hardware components beyond just software.

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

Here's why:

  • Intended Use: The intended use clearly describes a system for delivering radiation therapy (brachytherapy) directly to a tumor or tumor bed within the body. This is a therapeutic procedure, not a diagnostic test performed on samples outside the body.
  • Device Description: The description details a system for placing a radioactive source internally or close to a tumor. This aligns with a therapeutic device, not a device used for analyzing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device's function is to deliver treatment, not to perform such analysis.

    1. Description of the Device: The VariSource iX Series High Dose Rate Afterloader system is a computer controlled remote electro/mechanical system used for medical purposes, for placing a NiTiNol wire incorporating an irradiated iridium seed internally or close by, a malignant tumor or tumor bed in a practice known as brachytherapy. The device has up to 20 channels for treatment.

Hardware Platform and Operating System

The console control application runs on validated PCs under a Microsoft®¹ windows operating system. The firmware controlling the High Dose Rate Afterloader runs on an embedded Intel 188 processor.

Peripherals and Accessories

The iX Series control console provides real time information of wire position and system status and interfaces with a printer in order to provide a hard copy of a treatment prescriptions and delivery records. In addition the iX Series control console can receive treatment plans from a treatment planning application (not part of this submission), this information is transferred either manually using a USB2 drive, or via a network interface.

    1. Intended Use Statement: The VariSource iX System is a computer controlled remote HDR Afterloader used to place a high activity radioactive source within a needle(s) or applicator(s) which have previously been placed for a specified clinical purpose in a patient.
      The radioactive source (enclosed within the wire/cable) is driven via coupling catheters (Transfer Guide Tubes) from the Afterloader into needles or applicators within or on the patient.

The length of time and position that the High Dose Rate source spends within the needle or applicator is controlled in accordance with an Irradiation Treatment Prescription.

    1. Summary of the Technological Characteristics: The Substantial Equivalence Comparison Chart provides a comparison of the technological characteristics to those of the predicate device. This chart is located in Tab 9 of the submission.

Dear Ms. Tran:

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 (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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
