The summary describes a linear accelerator for radiotherapy and does not mention any AI or ML components or functionalities.
Yes
The device is described as an electron linear accelerator for intra-operative radiotherapy (IORT) used for the treatment of malignant and benign conditions by delivering high doses of radiation, which directly addresses a medical condition.
No
The device description clearly states it is an electron linear accelerator used to perform radiation therapy, which is a treatment, not a diagnostic procedure.
No
The device description clearly outlines physical hardware components: a Mobile Unit (STAND) which emits radiation, a Control Unit, and applicators, all connected by cables. This is not a software-only device.
Based on the provided information, the LIAC S device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the body (in vitro - "in glass"). They are used to diagnose diseases, monitor conditions, or screen for health issues by examining things like blood, urine, tissue, etc.
- The LIAC S is a device that delivers radiation to the body (in vivo - "in the living"). Its purpose is to treat tumors directly within the operating theatre.
The description clearly states its function is to deliver radiation for intra-operative radiotherapy, which is a therapeutic procedure performed directly on the patient. It does not involve the analysis of samples taken from the patient.

Device Description
LIAC S is an electron linear Accelerator used to perform radiation therapy during surgical procedures in an operating room on a patient from whom the Surgeon has just removed a tumor. This technique is known as Intra-Operative Radiation Therapy (IORT) and it is used for the treatment of malignant and benign conditions. IORT allows delivering of high doses of radiation directly to turnour site, while normal tissues are protected against dosage impact.
The available version of LIAC S is the 12 MeV one, with selectable energies of 6, 8, 10, 12 MeV and with electrical power requirement of 230 V, 50 Hz and 3kVA.
LIAC S model employs the same technology as its predicate, LIAC HWL, with the following differences:
-
- The Control Unit frame;
-
- The total length of the applicator;
-
- The design of the remote controller.
All the differences have no impact on the product performances.
The Equipment, LIAC S, is a system for Intraoperative Radiotherapy comprised of two main parts, Control and Mobile Unit, and the applicators.
The main parts, connected by a ten meters-long cable which transfers the signals and the power are:
- MOBILE UNIT (STAND). The Mobile Unit is a mobile component which emits the radiation. It is placed in the operating room near the patient with a remote-control device;
- CONTROL UNIT. The Control Unit is a mobile component too. It is connected to the mobile unit through a group of cables. It is the part of the device that controls the equipment.
Both the above listed components, the mobile unit (1) and the control unit (2), are joined by a cable of about 10 meters, to allow positioning the mobile unit in the operating theatre close to the patient, while the console control unit remains outside of the operating theatre allowing the operator to control the radiation.
The equipment can perform its action only if the Mobile Unit and the Control Unit are connected adequately and the applicator is installed.

3. Predicate Device
The LIAC S is substantially equivalent to the following predicate device, which is legally marketed in the US.
| Applicant | Device name | 510(k) Number |
|---|---|---|
| SIT SORDINA IORT | ||
| TECHNOLOGIES SPA. | LIAC HWL | K172961 |
LIAC S and its predicate device LIAC HWL (K172961) are both electron linear accelerators used for radiation therapy during surgical procedures in an operating room and they are both Class II devices.
5
LIAC S and the predicate LIAC HWL, at the same time, are both regulated under the regulation number 892.5050 and product code IYE.
LIAC S has the same intended use of the predicate device LIAC HWL (K172961). Both devices are electron accelerators that produce beams of electrons used in the radiation therapy treatment of both malignant and benign conditions.
The identified intended use is the radiation therapy treatment of both malignant and benign conditions, during surgical procedures. This technique is also known as "Intraoperative Radiation Therapy (IORT)" and it allows delivery of high doses of radiation directly to tumours or other sites while protecting surgically mobilized normal tissues against dosage impact.
LIAC S and its predicate LIAC HWL are equivalent devices. The only design differences between LIAC S and LIAC HWL are:
-
- Radiation performance parameters
- a) Dose Rate
- b) The surface dose
- c) Stray X-radiation
- d) Surface Surface Distance (SSD)
- e) Uniformity or Field Flatness
-
- Mobile and Control Unit mechanical design
-
- Components Applicator
- a) Applicator length
The differences listed above resulted not relevant for the device safety and effectiveness because, as stated into the comparison discussion, they are substantially equivalent to the predicate device LIAC HWL.
All the characteristics and/or performances have been validated with the same methods (i.e. standard compliance) used for the predicate device.
Thus, LIAC S is substantially equivalent to the predicate device LIAC HWL (K172961).
The differences between LIAC S and the predicate device are summarized in the following comparison table:
