The description focuses on mechanical components (ball screw drive, digital scale) and manual operation (hand crank) for positioning and measurement. There is no mention of algorithms, data processing for learning, or any terms associated with AI/ML.
No
The device is described as an "accessory to powered radiation therapy patient support assemblies" that "verifies and describes...the set-up of the couch/patient prior to treatment." It measures position and does not directly provide therapy.
No
Explanation: The device is described as an accessory that verifies and describes the set-up of a couch/patient prior to radiation therapy treatment by providing X, Y, and Z coordinates. It measures the movement of the couch top and displays values using a digital scale. This function is for alignment and verification of treatment setup, not for diagnosing medical conditions or diseases.
No
The device description clearly details physical components like interface plates, clamps, foot brakes, ball screw drive positioning tables, hand cranks, and digital scales, indicating it is a hardware device with integrated measurement capabilities.
Based on the provided information, the NOMOS® CRANE II is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "verify and describe, via a set of X, Y and Z coordinates, the set-up of the couch/patient prior to treatment." This relates to the physical positioning of a patient for radiation therapy, not the analysis of biological samples or substances from the human body.
- Device Description: The device description details mechanical components (ball screw drive positioning tables, digital scales) used for physical positioning and measurement. There is no mention of analyzing biological samples, reagents, or any other elements typically associated with IVD devices.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analysis of biological samples (blood, urine, tissue, etc.)
- Detection or measurement of analytes
- Use of reagents
- Diagnosis, monitoring, or screening of diseases based on biological samples
The NOMOS® CRANE II is clearly a device used in the physical setup and positioning of a patient for a medical procedure (radiation therapy), which falls under the category of medical devices, but not specifically In Vitro Diagnostics.

Device Description
The NOMOS CRANE II is an accessory to powered radiation therapy patient support assemblies. The NOMOS CRANE II attaches to the stationary base of the treatment table through a permanently installed interface plate and clamps to the accessory rails of the moveable couch top. A treatment table foot brake is also installed, if not already part of the treatment table, to further stabilize the stationary base. The treatment table foot brake is typically an accessory that can be purchased from the treatment table original equipment manufacturer (OEM). In cases where the foot brake is not an OEM accessory, one will be adapted or custom designed for the application. The CRANE II can be removed from the treatment table with only the interface plate remaining on the stationary base of the treatment table.
The CRANE II uses precision ball screw drive positioning tables, one for the Y-axis and one for the X-axis, to position the couch top relative to the stationary base of the treatment table. The positioning tables are operated using a small hand crank.
Each axis of the CRANE II incorporates a battery powered digital scale that measures the movement of the positioning table and therefore, the movement of the couch top itself. The digital scale may be set to display the value in inches, however, the operator's manual instructs the user to set the digital scale to display millimeters With the CRANE II attached, the couch top can be manipulated over a range of 12 inches (304.8 mm) in both the Y and X axis with no impedance on the couches range of travel in the Z-axis.

Dear Mr. Chishko:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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 redassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). 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 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a dassification for your device and thus, permits your device to proceed to the market.
