Intended Use
The IntraOp Alignment System is intended for use in applications where a mobile C-arm fluoroscope is incorporated to aid in diagnosis and treatment during spinal surgery. The IntraOp Alignment System is also intended to assist healthcare professionals in viewing, storing and measuring spinal alignment assessment images at various time points during surgery as well as planning spinal surgical procedures. The IntraOp Alignment System is intended for use with patients aged 18 years and older.
Device Description
The subject IntraOp Alignment (IOA) System consists of an optical tracking sensor, touchscreen computer, a mobile cart (stand) including an extension arm, and an electronics box with frame grabber, ports for video cables, power cables and external storage devices. The subject IntraOp Alignment System is a software-based system that from one end interfaces with a mobile C-arm fluoroscope through a video cable and a frame capture device to receive fluoroscopic images as they are acquired, and from the other end connects to an optical position tracking sensor to track the position and orientation of a C-arm in real-time. By using subject IntraOp Alignment System along the side of mobile C-arm fluoroscopy equipment, the user of the system can combine multiple fluoroscopic images, as they are being acquired, into stitched long bi-planar radiographic images for intraoperative visualization and assessment. The user is required to identify the location of the spine in both bi-planar views to scale the image content and provide information regarding the depth of the operative anatomy. The user can then use the measurement tools available on the subject IntraOp Alignment System to visualize and assess the spinal alignment for intraoperative planning of the surgical procedure. The subject IntraOp Alignment System has an optional capability to connect to a hospitalprovided Wi-Fi to import pre-operatively planned alignment parameters from an Alphatec cloud database. The subject IntraOp Alignment System also has the capability to export the post-operative alignment parameters to the cloud database. The subject IntraOp Alignment System sits outside the sterile field and is provided non-The subject device is intended for use by trained healthcare professionals, and sterile. appropriately trained clinical and non-clinical personnel. The subject device is intended for use in operating room environments of hospitals and surgical centers. System setup may be performed by trained non-clinical personnel.
More Information

No
The summary describes image processing, tracking, and measurement tools, but does not mention AI or ML algorithms being used for these functions.

No.
The device is intended to aid in diagnosis and planning of spinal surgical procedures by viewing, storing, and measuring spinal alignment assessment images. It provides information to assist healthcare professionals but does not directly treat a condition.

No

The device is intended to aid in diagnosis and treatment, and assist in viewing, storing, measuring, and planning, but its primary function as described is visualization, assessment, and planning of spinal alignment using fluoroscopic images and tracking C-arm position. While it "aids in diagnosis," it doesn't independently diagnose conditions. Its main purpose is to provide tools for visualization and measurement to assist healthcare professionals.

No

The device description explicitly states that the system consists of hardware components including an optical tracking sensor, touchscreen computer, mobile cart, and electronics box with frame grabber. While it is a "software-based system" in terms of its core functionality, it is not software-only as it includes necessary hardware for operation.

Based on the provided information, the IntraOp Alignment System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Intended Use: The IntraOp Alignment System's intended use is focused on aiding in diagnosis and treatment during spinal surgery by providing visualization, measurement, and planning tools based on fluoroscopic images. It does not involve the analysis of biological specimens.
  • Device Description: The device interfaces with a C-arm fluoroscope to process images and track its position. It does not interact with or analyze patient samples.

The device is clearly intended for use in a surgical setting to assist with image-guided procedures and surgical planning, which falls outside the scope of In Vitro Diagnostics.
