The description focuses on 3D printing and patient-specific design based on imaging data, with no mention of AI or ML algorithms for analysis, decision-making, or design generation. The design is generated by "3D Bolus Software Application (K213438)" and verified by a professional, not an AI/ML system.
Yes.
The device is used to attenuate and/or compensate external beam radiation during cancer treatment, which directly contributes to the therapeutic effect of radiation therapy.
No
This device is a bolus accessory used in radiation therapy to attenuate and/or compensate external beam radiation, not to diagnose a condition. It aids in delivering treatment, not in identifying a disease.
No
The device description explicitly states that the device is a "3D printed patient-matched radiation therapy accessory" and describes the manufacturing process involving 3D printing and silicone filling, indicating it is a physical device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic or monitoring purposes.
- Device Function: The TrueFit/TrueFlex Bolus is a physical accessory placed on the patient's skin during radiation therapy. Its purpose is to modify the radiation dose distribution, not to analyze biological samples from the patient.
- Intended Use: The intended use clearly states it's an accessory to attenuate and/or compensate external beam radiation during cancer treatment. This is a therapeutic application, not a diagnostic one.
The device interacts with the radiation beam and the patient's external anatomy, not with internal biological samples for diagnostic testing.

Device Description
TrueFit/TrueFlex Bolus is a 3D printed patient-matched radiation therapy accessory that expands the application of external beam radiation therapy by providing a patient-specific fit.
Patient imaging data from the treatment planning system (TPS) are used as inputs to generate digital design of the radiation therapy bolus (TrueFlex) by 3D Bolus Software Application (K213438), previously developed by Adaptiv. The resulting output Stereolithography (STL) file is compatible with the third-party 3D printers. A TrueFit Bolus is 3D printed by MJF technology using polyamide or polyurethane material. A Final TrueFlex Bolus device is manufactured by filling a mould with silicone.
The bolus is used in radiation therapy when a patient requires the total prescription dose to be delivered on or near the skin surface. The bolus acts as a tissue-equivalent material placed on the patient skin to account for the buildup region of the treatment beam.

Indications for Use Comparison
The referenced submission (K213438) includes both software components: stand-alone desktop applications, 3D Bolus and 3D Brachy, and corresponding patient-matched 3D printed radiation therapy accessories. The scope of current submission is limited to the patient-matched boluses under a new Indications for Use statement. The Indications for Use statement has been updated to increase the clarity. It is merely a documentation update, no actual change in the substance or meaning in the intended uses of predicate devices has been implemented.
Technological Comparison
Patient-matched 3D printed radiation therapy accessories are divided into two devices under specific brand names depending on the qualities of material.
TrueFit Bolus: The matter of the design change is addition of new material (polyamide) using the same printing technology referred as applicable for predicate device (K213438) that can be used for manufacturing of TrueFit Bolus. The addition of polyamide as a material expands the potential clinical use of the device due to:
- Compared to TPU01 (MJF): Higher rigidity of the material. It increases safety and effectiveness of the device in clinical cases when immobilization is beneficial.
- Compared to PLA (FDM): Similar level of rigidity, but higher consistency of printing technology in terms of radiological properties. It increases safety and effectiveness of the device in clinical use ensuring uniformity of radiological density and as a result - accurate delivery of radiation during the treatment.
TrueFlex Bolus: The design change involves the addition of a new manufacturing method for the device, using the following materials:
- Silicone - manufacturing of TrueFlex Bolus.
- . Polylactide (FDM), polyamide (MJF), photopolymer resin (SLA) – production of manufacturing accessories (moulds).
The addition of silicone as a material expands the potential use of the device due to its higher flexibility. It increases safety and effectiveness of the device compared to the predicate device (K213438) due to the following reasons:
- Silicone bolus conforms to convex and concave surfaces as well as fill shallow cavities, reducing air gaps and ultimately delivering a more accurate treatment.
- Due to the flexibility of the material, it facilitates comfortable placement on the patient.
As a part of the design changes, nonclinical assessments were performed to ensure the technologies and materials compatibility with device design in facilitating of radiation therapy accessories. All tests verified that the chosen methods performed as intended and did not affect the overall safety and effectiveness of the device and are equivalent compared to the ones covered by referenced submission.
