## Indications for Use

The Halcyon radiotherapy delivery system is intended to provide stereotactic radiosurgery and precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation treatment is indicated.

## Device Story

Halcyon is a medical linear accelerator (linac) for Image Guided Radiation Therapy (IGRT), Intensity Modulated Radiation Therapy (IMRT), and Volumetric Modulated Arc Therapy (VMAT). It delivers radiation via a single 6MV flattening filter-free energy beam. The system comprises an accelerator and patient support couch within a shielded treatment room, operated from an external control console. Key design features include a ring-gantry with enclosed moving parts and a stacked dual-bank multi-leaf collimator (MLC) that replaces traditional beam-limiting jaws. The device provides 3 degrees of freedom for couch movement. It is used by clinicians to treat tumors and lesions, with output used to guide and deliver precise radiation doses, potentially improving treatment accuracy and patient outcomes.

## Clinical Evidence

Bench testing only. Verification and validation testing conducted per FDA Quality System Regulation (21 CFR 820), ISO 13485, and ISO 14971. Electrical safety and EMC testing performed per IEC 60601-1 and IEC 60601-1-2. No clinical data presented.

## Technological Characteristics

Medical linear accelerator; single 6MV flattening filter-free energy; ring-gantry design; stacked dual-bank MLC; 3-degree-of-freedom couch. Conforms to AAMI/ANSI ES60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-1, IEC 60825-1, IEC 60976, IEC 61217, IEC 62274, IEC 62304, IEC 62366, ISO 10993-1, IEC 60601-2-68, and ISO 15223-1.

## Regulatory Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

|                      | accelerator and patient support within a radiation shielded treatment room |
|                      | and a control console outside the treatment room.                          |
| Intended Use         | The Halcyon radiotherapy delivery system is intended to provide            |
|                      | stereotactic radiosurgery and precision radiotherapy for lesions, tumors,  |
|                      | and conditions anywhere in the body where radiation treatment is           |
|                      | indicated.                                                                 |
|                      | The intended use is the same as the predicate.                             |

#### Indications for Use:

Halcyon is indicated for the delivery of stereotactic radiosurgery and precision radiotherapy for lesions, tumors and conditions anywhere in the body where radiation is indicated for adults and pediatric patients.

### Significant differences:

The significant differences compared to the predicate are:

- Multi-leaf collimator (MLC) consists of two sets of opposed leaf banks that are stacked. The upper leaf bank replaces beam-limiting movable jaws.
- . Ring design of gantry and stand; moving gantry parts are enclosed within panels
- . One Treatment Energy and MV Imaging Energy: 6MV, Flattening Filter Free
- 3 Degrees of Freedom of couch movement, compared with 4 or 6 in the predicate.

### Non-clinical Testing

Hardware and software verification and validation testing was conducted according to the FDA Quality System Regulation (21 CFR §820), ISO 13485 quality Management System standard, ISO 14971 Risk Management Standard and the other FDA recognized consensus standards listed below. Test results showed conformance to applicable requirements specifications and assured hazard safeguards functioned properly.

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "major" level of concern, since a failure or latent flaw in the software could directly result in serious injury or death to the patient or operator.

Electrical safety and electromagnetic compatibility (EMC) testing was conducted on this medical device. The system complies with the IEC 60601-1 standards for safety and the IEC 60601-1-2 standard for EMC.

### Standards Conformance

Halcyon conforms to the following standards. For full details refer to document: "Introduction to Standards Conformance Forms and Summary Reports."

- AAMI/ ANSI ES60601-1: 2005 IEC 60601-1-2: 2007 & 2014 IEC 60601-1-6: 2013 IEC 60601-2-1: 2014 IEC 60825-1 Ed. 2.0 2007 IEC 60976 Ed. 2.0 2007 IEC 61217: 2011 IEC 62274: 2005 IEC 62304: 2006 AAMI / ANSI / IEC 62366:2007/(R)2013 ISO 10993-1:2009 IEC 60601-2-68:2014 ISO 15223-1:2012
#### Conclusion of Non-Clinical testing

The outcome was that the product conformed to the defined user needs and intended uses and that there were no DRs (discrepancy reports) remaining which had a priority of Safety Intolerable or Customer Intolerable. Varian therefore considers Halcyon to be safe and effective and to perform at least as well as the predicate device.

#### Argument for Substantial Equivalence to the Predicate Device

A subset of technological characteristics and features of the current device is different to the predicate. These differences are all considered by Varian to be enhancements of the Intended Use remains unchanged. There are no new sites or tumor types listed in the Indications for Use compared with the predicate. There are no changes in the principle of operation of the device. The Verification demonstrates that the device is as safe and effective as the predicate. Varian therefore believes that Halcyon is substantially equivalent to the predicate.
