Yes
The device is intended for radiation therapy to apply a radionuclide source into or onto the body for treatment, clearly indicating a therapeutic purpose.
No
The device is a brachytherapy afterloading system, which is used for delivering radiation therapy to treat conditions like cancer, not for diagnosing them.
No
The device description clearly outlines multiple hardware components including the Treatment Delivery Unit (TDU) which houses the radioactive source, driving mechanism, and channel selector, the Treatment Communications Console (TCC), and the Treatment Control Panel (TCP). While software is involved in controlling these components, the device is fundamentally a hardware system with integrated software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for applying a radionuclide source into or onto the body for radiation therapy. This is a therapeutic procedure performed directly on a patient, not a diagnostic test performed on a sample taken from the body.
- Device Description: The description details a system for delivering radiation to a patient's body, including a radioactive source, a driving mechanism, and control systems. This aligns with a therapeutic device, not a diagnostic one.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on in vitro testing.
In vitro diagnostics are devices used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device's function is to deliver radiation for treatment, which is a therapeutic application.

Device Description
Flexitron is a computer controlled medical device for brachytherapy treatment.
The Flexitron Remotely Controlled Brachytherapy Afterloading System comprises subjoined listed subsystems:
- . TDU - Treatment Delivery Unit It houses the radioactive source in its built-in shielding safe, the microcomputer controlled driving mechanism and channel selector mechanism.
- . TCC - Treatment Communications Console For treatment program data entry, data storage and data displaying.
- TCP Treatment Control Panel . It comprises the basic operator elements for start and stop treatment and for displaying device status and used and remaining treatment time.
The TDU houses the shielding safe for storage of the radioactive source and the source drive mechanism for moving the radioactive source into treatment positions within an applicator and back into the safe. There is a channel selector mechanism for selecting one out of 40 treatment channels.
The TDU source drive mechanism and the channel selector mechanism are controlled by microprocessor based electronics. Sensors are applied and their signals are input for the embedded microprocessor for safe and reliable operation. The TDU is connected to mains via a built-in high isolation transformer and an AC/DC power supply converting the mains voltage level to 28 volt for internal machine operation.
The TDU is designed for positioning the source at 401 separate dwell positions in each of the 40 treatment channels and together with dwell time settings for each individual dwell position it enables the creation of isodose shapes targeted to the patients anatomy and geometry in order to irradiate the target patient body site and spare the healthy surrounding tissue.
Dwell positions can be programmed at 1 mm intervals. The maximum source outdrive distance is 1400 mm from the channel selector front plate.
Dwell times are programmable with increments of 0.1 second. Maximum dwell time is 999.9 seconds per position. Minimum dwell time is 0.1 second per position. A dwell position is skipped if its dwell time is 0 seconds.
Before the radioactive source is moved into a treatment channel a check cable is first moved into it. A check cable is of a similar construction of a source cable but without radioactive isotope. It is a measure to check the treatment channel for free passage of the source immediately after the check.
The TDU is connected to TCC via a serial data communications link to receive the patient treatment program and to return data of the performed patient treatment.
TCC allows for manually entering a patient treatment program or for electronically transferring a patient treatment program from Brachytherapy Treatment Planning Software (Treatment planning software is not subject of this 510(k) PreMarket Notification).
During patient treatment TCC displays treatment progress and logs patient treatment data and machine performance data in separate log files.
TDU is connected via another serial communications port to TCP.
TCP is a touchscreen device which is directly controlled from the TDU embedded microprocessor. TCP allows for starting the patient treatment when all conditions are fulfilled.
