The summary describes a manufacturing service for physical apertures used in proton therapy. There is no mention of AI or ML in the device description, intended use, or any other section. The device is a physical component designed by a separate treatment planning system.
No
The device, an aperture, is a passive component used in proton therapy to shape and focus the proton beam. It is not directly involved in delivering the therapeutic effect itself but rather modifies the therapeutic delivery. The therapeutic device is the proton therapy system.
No
The device is described as an aperture manufacturing service that produces solid apertures used to shape and focus a proton beam during cancer treatment. Its purpose is to guide radiation to the targeted area and block it from healthy tissue, which is a therapeutic function, not diagnostic.
No
The device description explicitly states that the device is a "manufacturing service" that produces "solid apertures" which are physical brass plates. This indicates a hardware component is being manufactured and provided.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens derived from the human body. The description clearly states that this device is a physical aperture made of brass, used to shape a proton beam for external radiation therapy. It does not interact with or analyze any biological samples.
- The intended use is for external beam proton radiation therapy. This is a therapeutic procedure, not a diagnostic one. The device is used to deliver treatment, not to diagnose a condition or provide information about a patient's health status based on biological samples.
- The device is a physical component of a larger treatment system. It's a beam-modifying device used within a proton therapy machine, not a standalone diagnostic test.
The device is a medical device used in the delivery of radiation therapy, but it does not fit the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
.decimal's Aperture manufacturing service manufactures the solid apertures for intensity modulation of external beam proton radiation therapy. The apertures are designed by the customer's treatment planning system to block radiation from hitting critical structures and healthy tissue while guiding the radiation to the targeted area.
In proton therapy for cancer, a proton beam is aimed at the cancerous tissue using a large "snout". The "snout" is rotated around the patient using a large, three-story gantry. While the patient lies on a treatment table, the gantry rotates around and points the snout at pre-determined positions to maximize efficiency and dose delivery to the tumor volume. Each gantry angle, or "port", requires two custom-made, beam modifying, patient specific devices: a range compensators and apertures.
The apertures are inserted into the gantry's snout to shape and focus the beam as it exits the gantry en route to the targeted area. The aperture is a brass plate with a 2D pattern/hole cut out of it, which defines the area that is to be treated with the proton beam. Apertures are generated out of the treatment planning system and are unique to each patient and each gantry angle (most patients will have 2-3 different gantry angles.) The outer dimensions/specifications are vendor specific, based upon the manufacturer of the proton delivery machines.

Intended Use:
.decimal's Aperture manufacturing service manufactures the solid apertures for intensity modulation of external beam proton radiation therapy. The apertures are designed by the customer's treatment planning system to block radiation from hitting critical structures and healthy tissue while guiding the radiation to the targeted area.
Summary of Technological Characteristics:
The device features of .decimal's Apertures are similar to the predicate device .decimal Tissue Compensator and Intensity Modulator. They both are used for external beam radiation therapy treatments, they both are used to block radiation and guide it to affected areas. The target population is identical and the use parameters are also very similar.

Dear Mr. Bennett:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may. therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
