Intended Use
ZDi Z-Tilt is intended for use by trained medical professionals for patient support and immobilization during external beam radiation therapy in clinics and hospitals. The Z-Tilt and accessories provide patient comfort and stability in various positions for radiation treatment. The Z-Tilt and is used in the treatment of cancer under the supervision and administration of licensed doctors and clinical staff.
Device Description
The Z-Tilt is a patient-positioning device designed specifically for applications within Proton Therapy. The Z-Tilt features a thin, low-stopping power backboard able to hold the heaviest of patients treated with proton therapy. The Z-Tilt offers a scoop feature that acts as a seat for patients to rest against. This seat allows an easily reproducible, fixed hip position. The scoop prevents the patient from sliding down the tilt, and also ensures thoracic alignment in the treatment area. The Z-Tilt is sixteen inches wide at its widest point, tapering into a ten-inch square to receive another ZDi device, the Z-Square. The Z-Square easily indexes to the Z-Tilt backboard to securely lock and index the custom foam patient molds to the device. The Z-Tilt is designed to be strong and sturdy, but with minimal amounts of material in critical areas of potential beam passage. The Z-Tilt backboard is attached to a slim, strong base. The base is narrow in the middle to allow beam passage, but wide enough to prevent wobble. The cranial end of the base is also a ten-inch square, holding hinged support legs to brace the backboard at various positions equaling four, eight, and twelve degrees; the most commonly needed patient tilt positions. The Z-Tilt base is designed with indexing holes to index to any standard index bar used on treatment tables. It is designed to remain within sixteen inches wide to prevent interference with table edges, table tracks, and CT bores. The Z-Tilt will have marks on each hole for accurate reproducibility of the Z-Square indexing system and for the leg supports for the incline. The patient will be in contact with their custom mold used on top of the Z-System. The associated accessories include: - Z-Square Indexing System for patient mold reproducibility - Z-Bar Index Bar for Z-Square mounting - Z-Box for custom formation of patient molds - Z-Pulls for arms-down reproducible arm positioning - Z-Foam for various foam patient supports under the custom patient molds - Z-Scoop for thoracic positioning on the Z-Tilt and table - Z-Roll for lateral positioning of the Z-Tilt
More Information

No
The device description and performance studies focus on mechanical properties, material testing, and biocompatibility of a patient positioning device. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.

No.
The device is a patient-positioning device used to support and immobilize patients during radiation therapy, not to provide therapy itself. The device is used as an aid for aligning the patient and supporting the patient while receiving their treatment.

No

The device is a patient-positioning and immobilization device used during radiation therapy. It does not collect or analyze medical data to diagnose a condition.

No

The device description clearly outlines a physical patient-positioning device made of materials like carbon fiber, with mechanical components like a backboard, base, legs, and indexing systems. It also includes various physical accessories. There is no mention of software as a component of the device itself.

Based on the provided information, the ZDi Z-Tilt is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly states that the device is for "patient support and immobilization during external beam radiation therapy." This is a therapeutic application, not a diagnostic one.
  • Device Description: The description details a physical device used for positioning and stabilizing a patient during treatment. It does not involve the examination of specimens from the human body.
  • Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. The Z-Tilt's function is entirely focused on supporting and positioning the patient for a therapeutic procedure (radiation therapy).

VI. Comparison of Technological Characteristics with the Predicate Device

Patient positioning for Radiation Therapy treatments is the technological principle for both the subject and predicate devices. The devices must support the patient in various positions to ensure the accurate delivery of a radiation therapy treatment. At a high level, the subject and predicate devices are based on the following same technological elements:

  • . Base Plate with adjustable legs for backboard support
  • Backboard for overall patient support
  • Arm positioning system
  • Thoracic Indexing System
  • Table Indexing System
  • Alignment marks
  • Mainly carbon fiber design, some plastic and metal components

The following technological differences exist between the subject and predicate devices, but in no way alter the safety or effectiveness of the subject device

VIII. Conclusions

Since the predicate device was cleared based on substantial equivalence to previously cleared, comparable devices, using the same materials, design, and having the same intended uses and manufacturing processes, the ZDi, Solutions, LLC Z-Tilt and accessories should be cleared based on their similarities to the predicate device and other devices. Technological, safety, effectiveness, biological, and all other factors of the subject Z-Tilt device are all substantially equivalent to the predicate device.
