The description focuses on the mechanical and electronic control of a radioactive source for brachytherapy, with no mention of AI or ML for tasks like treatment planning, image analysis, or device control.
Yes
The device is described as an afterloading brachytherapy device used to apply a radionuclide source into or onto the body for radiation therapy, providing a predetermined dose of radiation to tissue and organs. This directly indicates a therapeutic function by delivering radiation for treatment.
No
The device is described as a brachytherapy device used to apply a radionuclide source for radiation therapy, not for diagnosis. Its purpose is to deliver a predetermined dose of radiation to tissue and organs.
No
The device description clearly outlines numerous hardware components including a radioactive source, shielded safe, motors, indexer, position encoders, electronic control circuit boards, battery pack, power supply, source capsule, source cable, source tube, tungsten shielding, electro-mechanical key lock, source guide tubes, applicators, simulation source assembly, emergency hand crank, and an optional transportable trolley. This is a complex hardware system with integrated software for control, not a software-only device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The GammaMedplus 3/24 is a brachytherapy device that applies a radionuclide source into or onto the body for radiation therapy. It directly interacts with the patient's body to deliver treatment.
- Lack of Sample Analysis: The description does not mention any analysis of biological samples. The device's function is to deliver radiation, not to test or analyze samples.
Therefore, the GammaMedplus 3/24 falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

Intended Use / Indications for Use
The GammaMedplus 3/24 is a remotely controlled afterloading brachytherapy device used to apply a radionuclide source into the body or to the surface of the body for radiation therapy. The system is designed to provide a predetermined dose of radiation to tissue and organs by means of manipulating a radioactive source from a shielded position within in the device into a catheter, applicator, or needle, which has been placed within or on a patient. The remote afterloading device must be contained in a shielded facility during extension of the radioactive source. The GammaMedplus 3/24 may optionally be configured as a transportable device.

Device Description
The GammaMedplus 3/24 is a remote afterloading system used to deliver a radioactive source for use in high-dose rate brachytherapy. The Gammamed 3/24 is loaded with sources no greater than 10 curies. The GammaMedplus 3/24 differs from its predicate device in that it has only five treatment channels.
The GammaMedplus 3/24 consists of a remote afterloading device, an optional transportable trolley, and operator console. The GammaMedplus 3/24 remote afterloading device contains a radioactive source, a shielded safe in which to park the source when not in use, motors to drive the source, an indexer to determine the treatment channel for the source, position encoders for the source, electronic control circuit boards, a battery pack for backup power, and a power supply.
The radioactive material is sealed inside a stainless steel source capsule. The source capsule is attached to the source cable to form the source assembly. The source cable is also fabricated from stainless steel. The source assembly is housed inside a source tube. The source tube assembly is surrounded by tungsten metal which is used as shielding material. The radiation dose rate at a distance of one meter from the GammaMedplus 3/24 afterloading device when containing a source of the maximum activity is less than 3μGy/h.
An electro-mechanical key lock is provided to prevent actuation of the source when the afterloading device is not in use.
The source quide tubes attach to the afterloading device by means of a special quick connector. The source may be exposed through a particular channel only if the source guide tube is properly attached to this channel. The applicators to be employed in a particular treatment are connected to the GammaMedplus indexer by way of the source quide tubes.
The afterloading device also contains a simulation ("dummy") source assembly. This simulation source assembly is identical to the actual source assembly except that it does not contain radioactive material. The simulation source makes it possible to test the condition and location of the source guide tube and the applicators and their connections before carrying out the actual treatment. The device is equipped with 5 access channels, through which the single iridium192 source can be manipulated. The source exit port can be raised or lowered into a position that is optimal in relation to the particular patient. The position of the exit port of the afterloading device can be varied from 900 millimeters (34 inches) above the floor to 1800 millimeters (51 inches) above the floor. A wide range of flexible and rigid applicators is available for a wide variety of brachytherapy techniques.
The afterloading device is equipped with an emergency hand crank to permit the emergency retraction of the source. The hand crank is a "one way" hand crank, which allows only retraction of the source. It is not possible to expose the source using this hand crank.
The afterloading device can be installed onto a trolley for transportation. The GammaMed trolley consists of a rectangular chassis with four large casters for easy movement of the equipment. It has a manually operated brake that reliably maintains its position during treatment.
